Using DGP20E24T5/15โ€™s DC DC Converter with Isolated Module for High-Performance Applications

DGP20E24T5-15

DGP20E24T5/15 is a DGP20 series of DC DC Converters from the stable of Bel Power Solutions. The manufacturer made it into an isolated module; a module that further enhances the converterโ€™s performance.

In this article, we will share with you, some of the important attributes of this DC DC Converter.

What is a DC DC Converter?

First, let us start with an understanding of how a DC DC Converter works. A DC DC Converter is a type of device used to change the direct current voltage input level of an Integrated Circuit (IC) into another that has a direct current voltage output level.

By making this change, it enables the converter to optimize the performance of the target applications or devices, as per the required levels (output or input).

DGP20E24T5/15 is based on the DGP20 series of DC DC Converters manufactured by Bel Power Solutions.

The DC DC Converters in this series are known for the following:

1. Extended Input Voltage

The DGP20 DC DC Converter series use an extended input voltage, with a ratio of 2:1. This allows for the extended or improved operations of the converter to interface with multiple resources. These varieties of resources can be anywhere between 9 and 72 volts.

2. The Tri-Output Design

DGP20E24T5/15โ€™s architecture is based on a triple output model; a model that allows for the converterโ€™s improved functions via the high-performance 20-watt triple output.

Considerations for the Performance

Although DGP20E24T5/15 is rated a high-performance DC DC Converter, it does rely on certain parameters to get to that level.

By default, it doesnโ€™t necessarily need an external capacitance, but you want to consider that under a special circumstance.

If you are looking at getting the most maximum performance possible, it is worth it to use a capacitor with the DGP20E24T5/15. That way, you would be able to derive sufficient ripple current capacity, which is typically connected across the converterโ€™s input pins.

Likewise, DGP20E24T5/15 doesnโ€™t necessarily need an external output capacitance. However, considerations for this are to be made if there is a need to further reduce the system noise.

System Flexibility

DGP20E24T5/15 is one of the most flexible DC DC Converters you can come across. The systemโ€™s flexibility is derivable from the up to 11 watts of cubic inch for the power densities.

Increased Noise Filtration

DGP20E24T5/15 supports noise reduction during operation. However, there is also a chance to further the reduction, especially along the lines of filtration.

To do that, an additional output capacitance is to be added to work alongside the existing 10ยตF of tantalum and up to 0.1ยตF of ceramic capacitance.

To that end, it is possible to add up to 400ยตF of additional tantalum, just to filter the noise further.

DGP20E24T5/15 has Remote Operation

DGP20E24T5/15 is a DC DC Converter with remote operation, especially for supporting the On and the Off operations.

The Remote ON/OFF operation is one of the key mechanisms in the converterโ€™s low-power operation, as it can be used to switch the voltages. For example, the Remote ON/OFF operation/pin can be pulled down to the -INPUT to activate the low-power drain state.

While making the switch, make sure that the pin doesnโ€™t have more than +8 volts or be above 0.3 volts below the -INPUT.

DGP20E24T5/15โ€™s Isolated Module: What Is It?

An Isolated Module, according to DigiKey, helps in regulating the electrical separation of input and output voltages โ€“ which is what the DGP20E24T5/15 DC DC Converter does.

By creating the isolation, the isolated module helps to prevent the presence of a direct conduction path of metallic property between the two circuit parts (input and output).

Thus, if you are not sure of the relevance to the DGP20E24T5/15 DC DC Converter, here are some of the benefits:

3. Noise Segmentation

Although DGP20E24T5/15 uses an external output capacitance for noise filtration and reduction, it does have some other ways of getting around it.

The isolated module plays an important role in this regard, through the breaking up of the ground loops. This activity leads to the separation of the circuit parts that are more susceptible to noise.

4. DGP20E24T5/15โ€™s Isolated Module Offers Different Levels of Isolation

The isolation of the input and the output voltages is the basic process. The isolated module also extends the isolation to the applicationโ€™s protection, whereby it prevents the isolated circuit parts from posing danger.

For example, it has what is called the Reinforced Insulation. This type of insulation offers double protection for the isolated circuit parts.

There is the Operational or Functional Insulation; an isolated module that doesnโ€™t offer shock protection, but makes up for that by offering operational security.

The Basic and Supplementary Insulation methods are also on the list. The former works by offering a single layer of insulation, which also offers shock protection. The latter, supplementary insulation, is ideal for adding more redundancy to the basic insulation model.

However, using the isolated module may come with some trade-offs, especially size-wise. The size of the module is higher than the other variant (the non-isolated module). Thus, it tends to take up more spaces in the target applications or circuit boards.

Conclusion

DGP20E24T5/15โ€™s combination of the extended input voltage range and the high-performance, 20-watt triple output combine to give the converter a higher operating voltage.

Now that you know about some of the properties, make sure that the application or use case is either for telecom consumer electronics or battery-powered applications. That is because those two are the major use cases for the DGP20E24T5/15 DC DC Converter.

How Does the AT24CM02-SSHM-B EEPROM Memory Function?

AT24CM02-SSHM-B

Consumer electronics are using memory to store information and to transmit the same. The EEPROM memory is one of the popular memory types. In this article, we discuss the workings of AT24CM02-SSHM-B, one of the popular EEPROM memories from Integrated Circuit (IC) manufacturer, Microchip Technology.

How Does an EEPROM Memory Work?

EEPROM is a format of semiconductor device, optimized for storing information/data on the Integrated Circuit (IC). It is a non-volatile memory designed to process data transfer via the I2C memory interface.

AT24CM02-SSHM-Bโ€™s Writing Operations and Error Detection Capabilities

Error detection is now an integral component or feature in most Integrated Circuits (ICs). AT24CM02-SSHM-B is not lagging in that respect, either. The built-in error detection capabilities interface with the writing operations.

First, let us talk about the writing operations. AT24CM02-SSHM-B uses a Start Condition, which the host uses to initiate a data transfer sequence. Upon the activation of the said condition, it would then be up to the built-in Error Detection and Correction (EDC) logic scheme to find the โ€œfaults.โ€

The EDC logic scheme then reads the 38-bit of Error Correction Codes (ECCs) in the EEPROM Array. By reading these codes, the EDC finds out if there is anything out of place by comparing the 6 ECC bits from the EEPROM with the four connected 8-bit bytes from the EEPROM Array.

The comparison reveals whether there has been any incorrect reading of any of the bytes from either section (the EEPROM Array and the EEPROM).

In the case of an incorrect data reading, what the Error Detection and Correction (EDC) logic does is to use a correct or updated value to replace the incorrect bit. That way, everything relating to the data would be uniform by the time it is serially clocked out.

AT24CM02-SSHM-B has Higher Data Reliability

Everything relating to data must not be treated with kidโ€™s gloves, especially when it is used in consumer electronics. Microchip Technology, the manufacturer of AT24CM02-SSHM-Bโ€™s EEPROM Memory function takes that into consideration.

It maintains the highest data reliability standards by first using the endurance rating up to 1 million write cycles. It also keeps the data or information safe with the 100-year data retention.

AT24CM02-SSHM-B Attributes

AT24CM02-SSHM-B Pin Considerations

Pins play an essential role in the functions of an Integrated Circuit (IC). Careful considerations are to be made when working with these pins. AT24CM02-SSHM-Bโ€™s pins are important elements in the data writing capabilities.

Up to eight (8) different pins are supported, namely:

  • VCC
  • NC
  • WP
  • A2
  • SCL
  • GND
  • SDA

These pins cut across different ball compositions and functions, such as:

  • Device power supply
  • No connect
  • Ground
  • Write-protect
  • Device address input
  • Serial clock
  • Serial data

The SDA and SCL Pins: Whatโ€™s the Difference?

The Serial Clock (SCL) and the Serial Data (SDA) pins appear to share the same function, but there is a thin line differentiating one from the other.

On the one hand, SDA is an open-drain bidirectional Input and Output (I/O) pin meant to make serial transfer or movement of data to and from the (target) device.

On the other hand, the Serial Clock (SCL) provides a clock to the (target) device. The clock helps regulate the movement, transfer or flow of data to and from the (target) device.

Thus, the difference between the two is that despite aiding data transfer to and from the target device, the SDA differentiates from the SCL because it is an Input and Output (I/O) pin, while the latter provides a clock for the data transfer.

Device Address Input (A2)

This type of pin is used primarily for connecting two or more Serial EEPROM devices. For that to work, the Device Address Input (A2) is first hard-wired either to the VCC or to the GND pins.

Either way, the hard-wiring paves the way for the creation of compatible interfacing between the GND or the VCC pins with the additional two-wire Serial EEPROM devices. That way, multiple devices can be addressed or connected via a serial bus system.

Write-Protect (WP)

The Write-Protect or WP pin is used to enable the normal writing operations in the AT24CM02-SSHM-B EEPROM memory.

For the writing to be enabled, AT24CM02-SSHM-B is first connected to the Ground (GND) pin.

However, it provides protection for the data in the form of prohibited access. To enable this, the Write-Protect (WP) is connected directly to the Device Power Supply or VCC pin. By making this direct connection, Write-Protect (WP) prevents the memory from exposure, especially for the write operations.

How the VCC and the GND Pins Work in AT24CM02-SSHM-B

The remaining pins to analyze are the Ground (GND) and the Device Power Supply (VCC) pins.

They work together in the sense that the VCCย is the major supply voltage to the device, while the GND serves as the โ€œground reference for the power supply.โ€

The Data Transfer Process

Data transfer is done via AT24CM02-SSHM-Bโ€™s I2C-compatible two-wire digital serial interface. Through this interface, the memory communicates or interfaces with the host controller. For emphasis, the host controller is the core initiator and manager of the client devicesโ€™ read and write operations.

It also oversees the enablement of the two-way data transfer process, allowing the client devices and the host (bus host) to transfer and receive data on the same bus.

The data transfer process typically involves the reception of the clock from the host through the Serial Clock (SCL). Once this has been done, the next stage would be the reception and transfer of the data information and command from the Serial Data (SDA) pin.

Conclusion

AT24CM02-SSHM-B is an excellent EEPROM memory required for surface-mounted devices needing excellent command and data transfer to and from the target devices/circuit boards.

Using light-based sensors, they generate biometrics, which can be useful for determining health problems and detecting abnormalities. Wearable devices also provide insight into physiological systems, which can lead to improved treatment options. Approximately 85% of healthcare costs are related to chronic illnesses, so this technology can be a great ambulatory solution for monitoring physiological parameters.

Wearable technology is also helpful for preventing diseases. The use of health monitors helps detect symptoms early and encourages healthier lifestyles. In addition, these devices help patients compare their results to goals, and they can track progress against those goals. With the help of modern technology, healthcare providers can monitor patients around the clock, identifying early signs of serious illnesses and offering preventive care.

Fashion and Smart Clothing

Fashion and smart clothing uses of wearable technology are emerging, and consumers have a mixed reactions. The rejection of smart clothing is often due to a lack of consumer understanding or an unwillingness to invest in new products. However, it does not necessarily mean that consumers will not adopt new products if the design is not appealing. This study used a preliminary interview to gather data on consumer perceptions of smart clothing and then conducted in-depth interviews with 30 consumers from different demographics. The research focused on consumer attitudes, preferences, and opinions about smart clothing and whether or not they would purchase the product.

The development of smart clothing is a complex process. First, designers must ensure the clothing is practical and attractive and should consider the characteristics of consumers. For example, color choice must take into account the age group of the target consumer. Older consumers will want to wear conservative, muted colors, while the young prefer vibrant ones. In addition, children’s clothing should be designed to focus on novelty and fun. While wearing smart clothing, however, designers must consider the concealment of electronic components.

Although most developments of smart clothing are still taking place in research labs, there are several examples of the integration of wearable technology into clothing. For example, Levis recently introduced a denim trucker jacket with Google software. This jacket allows users to read messages, respond to notifications, and play music. These devices target urban cyclists, but smart clothing can be useful for various purposes.

Performance monitoring and navigation tracking

Wearable technologies provide information about human performance by collecting various metrics. These metrics can be based on running speed, the inclination of the terrain, and heart rate. Some wearable devices are capable of estimating the workload based on these metrics. These devices are suitable for both ambulatory and clinical settings.

Wearable technologies can be worn on the body or embedded within clothing or other semi-rigid structures. These devices can communicate through the human body using appropriate transmission mediums, such as BLE, Wi-Fi, and cellular data. You can store the collected data from wearable devices for long-term analysis. The devices may not process the data locally but instead, send it to a remote computer equipped with powerful processing capabilities.

Wearable technology is gaining popularity in both elite and general populations. Its widespread use in the health and fitness industry has led to significant growth in the market. A recent study examined the effectiveness of five wrist-worn devices against a respiratory gas analysis method. The authors found that most of these devices had a mean absolute percentage error greater than 10% and often underestimated the amount of oxygen a person is breathing. Nevertheless, this study highlighted the potential benefits of wearable technology for health and fitness.

PCB manufacturing and assembly services

Wearable PCBs are often made using flex PCB technology, a type of flexible PCB used in many medical devices. These PCBs have a low ripple effect that reduces system noise and are compact. These PCBs also enable clean signal transmission. However, one of the biggest challenges in the PCB manufacturing process for wearable devices is dielectric constant tolerance. Many devices require a +2% tolerance, but some require a higher one.

PCB manufacturing services for wearable devices are becoming increasingly important as technology improves. These devices are becoming compact, fast, and stylish and should follow strict standards during manufacture.

Wearable devices and PCB manufacturers

Wearable PCB manufacturers face numerous challenges in designing the electronics that go into such devices. The primary constraints are the reduced footprints and low-profile packages. The circuit boards used in these products must be moisture-proof, and the materials used should be durable and reliable. PCBs manufactured for wearable devices must comply with safety and quality standards.

Wearable PCBs can range in structure from two to eight layers, with two to four being the most popular. However, when creating a PCB for a wearable device, it is crucial to use a multilayer structure to minimize electromagnetic interference and crosstalk. Additionally, wearable PCBs can include a ground plane between power and signal planes. This prevents crosstalk and enhances electromagnetic compatibility.

The manufacture of PCBs for wearable devices should use advanced technologies that can handle the high-performance demands of these devices. The materials used should have a minimum solution thickness and exhibit low laminate loss. Wearable PCBs are typically small-sized and can be as small as the size of a penny.

EVA-M8M-0-10 RF Receiver

EVA-M8M-0-10

Ever wondered how an RF Receiver works? More especially, how the EVA-M8M-0-10 works as an RF Receiver? We are going to talk exclusively about all that in this article.

But before we proceed, we are going to talk about some of the things you need to know about this device. First, EVA-M8M-0-10 is an RF Receiver and it is primarily used with devices or applications requiring a modulated radio frequency.

When we are talking about these applications, we are specially mentioning the likes of USB, UART, Pads for Pins and Solder Pads. EVA-M8M-0-10โ€™s RF Receiver is also used with I2C, I2S, Serial Interfaces and Parallel Interfaces.

With that being said, let us dive right into the article and talk about other things you need to know about the EVA-M8M-0-10.

How EVA-M8M-0-10 Works

Like most RF Receivers out there, EVA-M8M-0-10 works by taking in a modulated radio frequency. Once the frequency is taking in, it demodulates the radio frequency before passing the obtained data along for onward processing inside the system.

u-blox manufactures this EVA-M8M-0-10 and made it available for a wide range of applications, including but not limited to data-logging and space-sensitive applications. The idea is that can be used for a variety of purposes or applications, because it is a general-purpose RF Receiver.

EVA-M8M-0-10โ€™s GNSS Module

EVA-M8M-0-10 uses the GNSS Module or protocol, alongside other modulations like GPS, BeiDou and GLONASS.

What is a GNSS Module and what role does it play in the EVA-M8M-0-10 RF Receiver? The full name is Global Navigation Satellite System (GNSS). It is a type of device used to form a constellation of the different satellites that provide signals from space. These signals are then pushed to or transmitted to the GNSS receivers; providing a combination of timing data and positioning in the process.

In terms of the EVA-M8M-0-10 RF Receiver, the GNSS Module aids in the simultaneous acquisition and capture/obtaining of the multiple satellite constellations. These would then be used for navigation, positioning and tracking applications.

As a general-purpose RF Receiver, the applications or use cases can also be extended to the space-centric applications.

1. Concurrent GNSS Module

Agreed, EVA-M8M-0-10 uses a GNSS Module, but there is another upside to it โ€“ it is concurrent. The concurrency of the module delivers the highest accuracy while ensuring that the processes are seamless.

It is worth pointing out that the GNSS Module relies on some of the best component-parts, including but not limited to BeiDou, GPS, GLONASS, and Galileo.

EVA-M8M-0-10 Supports Several Interfaces

Although the GNSS Module makes up for most part of the signal obtaining and delivery, a lot still relies on other peripherals. It is in light of it that the several interfaces provisioned on EVA-M8M-0-10 come in handy.

For one, these interfaces combine to deliver the highest signal delivery possible. While the embedded firmware is primarily used for protocol-based specifications/applications, the others are used for memory, and data communication purposes.

This is a breakdown of how each of the interface work:

2. Interface Selection (D_SEL)

This is a dedicated interface for interfacing or choosing the best communication medium. When the D_SEL interface is activated, it can choose among the GND, DDC and UART interfaces for the communication.

For example, the GND interface is selected after the D_SEL pin has been set to the logical โ€œ0โ€. The setting permits the Ground (GND) interface to become the default communication interface.

Otherwise, the D_SEL pin can be set to the logical โ€œ1โ€ to enable the duo of the DDC and UART interfaces to be used as the default communication interfaces.

3. UART Interface

Although it is used in the former reference for communication interfacing, the use case of the UART interface is primarily for communication. In this case, it has to be configured to support the configurable baud rates, as that is the basis for the usage as a communication interface to the host.

4. Serial Quad Interface (SQI)

This type of interface is used when looking to connect (multiple) interfaces to the EVA-M8M-0-10 RF Receiver.

How it works? It uses an optional external flash memory to make the connection. The memory referenced now can also be used for other purposes, ranging from data logging and making updates to the firmware.

5. Power Mode

EVA-M8M-0-10 uses a power-optimized architecture, which offers the best power performance, while cutting down (excessive) power, where possible.

To get the best power performance, EVA-M8M-0-10 has been optimized to work with multiple modes, such as the Power Save Mode and the Continuous Mode.

If you are working with the Power Save Mode, the use case is mainly to optimize the RF Receiver for the lowest power usage. On the other hand, you can activate the Continuous Modeย if you are looking to get a mix of balanced power and low-power optimizations.

6. Ease-of-Integration

Consumer electronics now have several integrated components, including RF Receivers. EVA-M8M-0-10 is not an exception.

The ease-of-integration is drawn from the QFN-like package/case, which allows for the flexible integration in a wide range of devices.

Most importantly, the package allows for the production and availability of the GNSS Modules in both 500 reels and pieces. That way, it becomes easier to integrate the receiver into the target applications โ€“ especially in the small form-factor devices.

7. EVA-M8M-0-10 is a Product-Diverse RF Receiver

The general-purpose optimization aside, EVA-M8M-0-10 is also ideal for several use cases, thanks to the product diversity. The diversity in this case refers to the optimization of the receiver to work across different facets. It is also because of the following considerations:

8. Excellent Timing Solutions

EVA-M8M-0-10โ€™s GNSS Module solutions support the configuration of applications or devices with a focus on precise timing, standard precision, dead reckoning and high precision solutions.

9. Customized Solutions

u-blox, EVA-M8M-0-10โ€™s manufacturer, uses the โ€œsilicon,โ€ thus making the general-purpose applicationsโ€™ support more impressive. By using the companyโ€™s exclusive architecture, there is every assurance that stabilized product life cycles, controlled quality, excellent customer support and the highest performances are assured.

Conclusion

To sum it up, EVA-M8M-0-10 is a high-precision, optimized-cost and easily integrable RF Receiver for general-purpose applications.

Ensuring Optimized Power Consumption with the ATMEGA1284P-AU Microcontroller

ATMEGA1284P-AU

ATMEGA1284P-AU uses an AVR-enhanced RISC architecture combined with the 1 Million Instructions Per Second (MIPS) per Megahertz (MHz) to balance the power consumption with the processing speed.

We have made this blog post to help you understand how the ATMEGA1284P-AU Microcontroller (MCU) works.

The MIPS Architecture

MIPS stands for Million Instructions Per Second (MIPS). Essentially, it refers to the number or volume of instructions that can be processed with the ATMEGA1284P-AU Microcontroller. Like every other Microcontroller, ATMEGA1284P-AU works by storing data inside the circuit board.

By processing up to 1 million instructions per Megahertz (MHz), it sure is the go-to MCU for faster transactions.

Interestingly, not all Microcontrollers (MCUs) balance the performance with the processing speed. That is one feature that sets ATMEGA1284P-AU apart from the others โ€“ it balances processing speed with power consumption, through the MIPS.

Cross-Section of Peripherals

ATMEGA1284P-AU Microcontroller

ATMEGA1284P-AU uses some of the best peripherals you can find out there. From the PWM to the Brown-out Detector, it uses most of these peripherals to deliver the best performances.

Below is a breakdown of how each of the peripheral works:

PWM Channels

PWM stands for Pulse Width Modulation. According to Wikipedia, it is a โ€œmethod of reducing the average power delivered by an electrical signal.โ€ The average power reduction is facilitated by the bit-by-bit segmentation of the signals, typically into discreet parts.

Pulse Width Modulation performs many functions, ranging from voltage regulation, and controlling the amount of power delivered to a load. In this regard, the power delivery is done in a way that it doesnโ€™t trigger voltage issues resulting from the delivery of linear power through resistive means/channels.

ATMEGA1284P-AU comprises 6 PWM Channels.

Non-Volatile Memory Segments with High Endurance

ATMEGA1284P-AUโ€™s memory segments are not only non-volatile, but also have one of the highest levels of endurances.

The following are some of the attributes in that regard:

Programming Lock

ATMEGA1284P-AU protects the software through the Programming Lock feature.

Boot Code Selection

ATMEGA1284P-AU allows for an optional selection of the boot code, especially if independent lock bits are to be used.

The attributes in this regard include a True Read-While-Write Operation and an In-System Programming via the On-Chip Boot Program.

Data Retention Capabilities

The internal data storage function of a Microcontroller (MCU) helps to protect the circuit board against losing most of the configurations.

For that purpose, digital circuit designers look for the MCU with the best-possible data retention capabilities.

ATMEGA1284P-AUโ€™s data retention capability is enabled through the high endurance, non-volatile memory segments. It can retain data for 20 years at 85หšC or for 100 years at 25หšC.

QTouch Library Support

Digital circuit designers looking to use the ATMEGA1284P-AU Microcontroller (MCU) are further empowered by the QTouch Library.

It is a dedicated platform for getting royalty-free software needed for configuring the ATMEGA1284P-AU MCU. The library comprises both the IAR and GCC; both used for developing the โ€œtouch applicationsโ€ based on the Microchip AVR Microcontrollers (MCUs) and the AT91SAM standard.

The supported QTouch Library also includes support for up to 64 sense channels and the combination of capacitive touch buttons, wheels and sliders.

Special Features

Besides the data retention, lowered power consumption and the support for the QTouch Library; ATMEGA1284P-AU also offers some other attributes.

Called the special microcontroller features, they are dedicated attributes offered for special purposes or functions.

The following are some of the special features:

1. Programmable Brown-Out Detection

Also called the BOD, the Brown-Out Detection is a dedicated facility inside a Microcontroller (MCU), serving the purpose of monitoring the dip or a drop in the MCUโ€™s voltage supply.

Super User noted that a voltage is considered to be in an undervoltage condition, when the Alternating Current (AC) drops below the nominal or predefined below. In most case, the drop is highlighted when there is a 10% drop below the predefined value.

So, what the Brown-Out Detection (BOD) does in the ATMEGA1284P-AU MCU is to find out when this nominal value drops. It is also programmable, meaning that it can be configured to meet different applicationsโ€™ requirements.

2. Internal Calibrated RC Oscillator

Oscillators are popularly used in Microcontrollers (MCUs), but that of ATMEGA1284P-AU is based on the Internal Calibrated RC design. According to the manufacturer, Microchip Technology, this type of oscillator is delegated when the internal RC oscillator is to be used as the CPU clock source.

3. Support for Several Sleep Modes

The ATMEGA1284P-AU is โ€œput to sleepโ€ when not in use. However, putting it to sleep might cause most of the components to stop working for the time being. This can, however, be tackled with the multiple sleep modes it provides.

Choices can be made from any of the following:

  • Extended standby mode
  • Idle sleep mode
  • Standby mode
  • ADC noise reduction mode
  • Power-down mode
  • Power-save mode

Each of those modes can be further programmed to adapt to the target applicationsโ€™ power-saving requirements.

Programmable Watchdog Timer

ATMEGA1284P-AU uses a programmable watchdog timer. A watchdog timer is the dedicated timer monitoring the operations of a Microcontroller (MCU), just to find out if the MCU is operating normally or not.

Therefore, it is to be regarded as the โ€œwatcherโ€ that โ€œkeeps an eye onโ€ the Microcontroller (MCU)โ€™s operations.

ATMEGA1284P-AUโ€™s watchdog timer is not just programmable, but also comes with the separated on-chip oscillator.

Here are some of the attributes making up ATMEGA1284P-AUโ€™s programmable watchdog timer:

Selectable Time-Out

Due to the configuration for fault or abnormal operation detection, the watchdog timer might be unable to give the Microcontroller (MCU) the space to function beyond a lapse.

That informs the reason behind the integration of a programmable feature called the selectable time-out function on ATMEGA1284P-AUโ€™s watchdog timer. It offers up to 16ms to 8s of timeout; giving the MCU some time to recover after a lapse.

Hardware Fusion

ATMEGA1284P-AUโ€™s watchdog time also has a possible hardware fuse Watchdog Always on (WDTON) function. It works best for the fail-safe mode.

The other attributes of the watchdog timer are:

  • Interrupt and system reset
  • Interrupt mode
  • System reset mode

Final Words

ATMEGA1284P-AU regulates power consumption to the barest minimum, keeps the MCU active through the programmable watchdog timer and regulates electrical signal transmission via the Pulse Width Modulation (PWM) function.

DAC80508ZRTET: A Pin-Compatible Buffered-Voltage-Output Digital-to-Analog Converter

DAC80508ZRTET

DAC80508ZRTET is a Digital-to-Analog Converter (DAC) with support for the buffered-voltage-output. Manufactured by Texas Instruments, it is the ideal DAC for low-power applications.

Perhaps, one of the most outstanding features is the composition of a 2.5-volt, 5-ppm/หšC internal reference; a composition that eradicates the need for an external precise reference.

The DAC Family

DAC80508ZRTET belongs to the broader DAC80508 family of Digital-to-Analog Converters (DACs). This family of DACs is reputed for the optimization for low-power applications.

By this classification, DAC80508ZRTET also offers a balanced power for the DAC outputs via the power-on-reset circuit.

Small Form-Factor

If you are looking for a DAC with the most-minimized real estate, DAC80508ZRTET has to be on the list.

It supports form-factors, through the availability in smaller packages. For one, it is available in the 16-pin WQFN package with a body size of 3.00 mm by 3.00 mm. It is also available in the 16-pin DSBGA small package, with a body size (NOM) of 2.40 mm by 2.40 mm.

The small package optimization makes it ideal for the following applications:

  • Data Acquisition Systems (DAS)
  • Optical networking applications
  • Industrial automation devices
  • Wireless infrastructure

The Low-Power Design

DAC80508ZRTET is one of those Digital-to-Analog Converters (DACs) with a premium placed on power optimization. The low-power design is based on the use of the low-power 0.6 mA/Channel, which operates at 5.5 volts.

To that end, it offers an integrated power-on-reset circuit, which aids the power up or booting of the DAC, especially in the absence of midscale or zero scale. In that light, you can rely on it to maintain the base outputs of the DAC, and hold the same until a valid code is written to the target device or application.

The low-power channel is just a tip of how it is low-powered. The other aesthetics include the per-channel power-down function. This function is responsible for reducing the deviceโ€™s power consumption to the barest minimum of 15 ยตA.

The operation of the 0.6 mA per channel is also a great customization that makes DAC80508ZRTET an ideal DAC for the battery-operated devices or applications.

DAC80508ZRTET Uses an Internal Reference

DAC80508ZRTETโ€™s internal reference paves the way for the DAC to expunge the need for external, precision interfaces.

At the core of the internal referenceโ€™s functionality is the low drift operation with a typical 2 ppm/หšC. It also features an initial accuracy of ยฑ5 mV maximum.

Flexible Interfaces

The flexibility of an Integrated Circuit (IC)โ€™s interfaces can make or mar the functionalities. DAC80508ZRTETโ€™s interfaces are flexible as they allow for the customization and or further optimization of the DAC.

The flexible interfaces enable the operation or functioning of the DAC, as per the industry-standards for both Microcontrollers and Microprocessors.

To get an idea of the customization, its serial interface operates up to 50 Megahertz (MHz) of clock rates and a serial interface operation of 5.5 volts (maximum) via the VIO pin.

The flexibility of the peripherals is not limited to the interfaces, as DAC80508ZRTET is flexible with the output configurations. The configurations here include:

  • A clear output function
  • User Selectable Gain of ยฝ, 1 and 2.
  • The DAC80508ZRTET DAC can be reset to either the midscale or the zero scales.

The Benefits of DAC80508ZRTETโ€™s DAC

Digital-to-Analog Converters (DACs) pave the way for the conversion of transmission of a digital data or signal to a corresponding audio signal or data. Ordinarily, a digital data cannot take the place of an audio data because the two arenโ€™t the same โ€“ and vice-versa.

Through the Digital-to-Audio Converter (DAC), it becomes possible to convert or make a digital data stream into an analog audio signal or data stream.

Here are some of the benefits to leveraging DAC80508ZRTETโ€™s DAC:

1. Limited Noise

DAC80508ZRTETโ€™s DAC doesnโ€™t generate much noise because of the thermal noise design created by the passive components, including resistors.

The thermal noise design makes DAC80508ZRTETโ€™s operation seamless, as it can potentially cut down the noise to less than 21 bits. From the information in the datasheet, the noise level is rated as 16-bits.

2. The Buffered-Voltage-Output Design

DAC80508ZRTETโ€™s buffered-voltage is based on the Digital Buffer, which Wikipedia describes as an โ€œelectronic circuit element used to isolate an input from an output.โ€

The isolation keeps the different elements (input and output) independent and fully operation. Wikipedia also confirms that the digital buffer doesnโ€™t necessarily have to make changes to the original state of the input and the output, because it allows the two to work in isolation without attenuation or amplification.

The buffered-voltage-output design in the DAC80508ZRTET is ideal for increasing the DACโ€™s maximum output range from 0 V to VDD.

In addition to the load-driving potential of up to 2 kโ„ฆ, the buffered-voltage-output also makes the driven load to be parallel to the 10 nF to Ground (GND).

3. DAC80508ZRTET Supports Wide Operation

Not all DACs support a broader operation, but there is an exception with DAC80508ZRTET. It supports a wide range of operations, including an operating temperature up to 125หšC.

Factors to Consider when Choosing a (DAC80508ZRTET) DAC

With the several functions it performs, it is not a doubt that DAC80508ZRTET is one of the best Digital-to-Analog Converters (DACs) to buy.

But it is not better to make the buying decision based on assumptions. Here are some of the factors that are worth considering to influence that decision:

What is the Dynamic Range?

A DACโ€™s dynamic range is the distance or the difference between the smallest and the largest signals received by the converter. The shorter the distance or the difference, the better.

Resolution

Also called the โ€œnoise levelโ€ the resolution of a Digital-to-Analog Converter (DAC) infers to the output noise production level(s).

Already, we mentioned that DAC80508ZRTETโ€™s resolution or noise level is 16-bits, as the output levels of the noise is represented in specific numbers of bits.

Total Harmonic Distortion and Noise

The acronym for this is THD+N. It also has to do with the (output) noise levels, only that this time, the focus is on the measurement of both the noise and distortion created by the Digital-to-Analog Converter (DAC).

Conclusion

The best way to choose a Digital-to-Analog Converter (DAC) is by checking the functions and some of the integral properties. That way, you are better informed on how the DAC works.

Although the DAC80508ZRTET has a lower or limited use case, it makes up for that with the improved architecture and the support for multiple peripherals and interfaces.

What Does Wireless Charging Mean and How Does it Work?

Wireless Charging

Wireless charging has been existing since the late 1800โ€™s. Around this time, Nikola Tesla, an electricity pioneer explained what magnetic resonant coupling was all about. Magnetic resonant coupling refers to the capability to transfer electricity through air by building a magnetic field between a transmitter and a receiver.

However, for about 10 decades, this technology didnโ€™t really have practical applications. It only worked for a few electric toothbrush models. Things are now better these days. Also, there are now various wireless charging technologies being used today. The major aim here is to cut cables from every appliance like smartphones, laptops, and even vehicles.

Wireless charging is becoming popular across several industries like manufacturing, automotive, and medical. This is because it promises to provide enhanced mobility and development that could enable Internet of Things (IoT) devices to receive power several feet away.

A wireless charging device is a piece of tech gear you can have. Furthermore it is very convenient and easy to use. Regardless of where you keep a wireless charger, you can charge your devices effortlessly. Whether it is on your desk or attached to your carโ€™s vent, this charger can make charging very convenient. People even take it for granted since it is very easy.

You may not fully understand what wireless charging does and how it functions. Also, you might use a wireless charger everyday but you are yet to understand its full capability. It is crucial to understand how wireless charging works and other capabilities they offer.

In this article, we will be explaining how wireless charging functions. Also, we will provide some reliable wireless charging phone accessories you can use.

What is Wireless Charging?

APPLE Wireless Charging

Wireless charging is available in a wide selection of phone accessories.  A wireless charger is a free station or pad with no messy cables. Also, using this charger entails placing a matching wireless charging device on it. Smartphones like Androids and iPhones can use wireless chargers. These devices can work with wireless charging if there are internal components and tech to help them accomplish such.

As an effective way of charging devices, wireless charging has become popular in recent years. Many people are beginning to know more about wireless charging and how they can use them daily.

The Basics of Wireless Charging

When you hear of wireless charging, it seems like one of those modern developments of 21st century. This is not the case as the basic principle behind wireless charging has been existing before the 21st century.

The science of wireless charging is similar to the resonant inductive coupling process of Nikola Tesla. This scientist used this process to light up his laboratory in the late 19th century. Also, Nikolaโ€™s inductive charging created a magnetic field between a receiver and a transmitter. Electricity transmission occurred via the airwaves.

Fortunately, Tesla was able to create the Tesla coil tower that transmitted electricity across a space. He hoped this invention could help to build a wireless power grid one day. This could help him integrated his inductive charging. Although, he couldnโ€™t achieve this before he died, but we are very close to achieving this in our modern world.  What he planned to achieve is close to how we use wireless chargers for our phones today.

In our world today, a wireless charging device features an electromagnetic coil. This electromagnetic coil is an induction coil in a charging base that builds a magnetic field which transmits energy to your device.

The question here is how does your phone receive electromagnetic energy? Well, there is an electromagnetic coil in your phone. This coil gets the energy discharged by the induction coil and then transmits that energy back to the battery of your phone. This is exactly how wireless charging works when you place a device on the wireless charger.

Wireless Charging Standards

There are two standards of wireless charging. These standards are the PMA standard and Qi standard. It is important to know how these standard works and the differences between them. Although the two wireless charging standards integrate the same inductive charging, they use different amount if wavelength.

Qi wireless charging

The Wireless Power Consortium (WPC) created the Qi wireless charging standard. This charging standard is more common than PMA wireless charging. Also, the Qi wireless charging method is widely integrated inside wireless charging devices. It is highly preferred among electronic device and phone manufacturers. This charging standard features a 100-205 KHz band.

PMA wireless charging

PMA simply refers to Power Matters Alliance. It is a wireless charging standard that utilizes wavelengths between the range of 277 to 357 KHz band.

What is Qi Charging?

In this section, we will discuss how Qi charging works. Qi charging is simply an optimized inductive charging. This charging method enables wireless charging. Also, it can only charge the batteries of compatible devices by integrating induction transfer. Furthermore, there are no separate cables, adapters, or chargers. Your device must be compatible with the wireless pad. All you just need to do is to place your compatible device on the wireless pad.

Qi is known as the standard for wireless charging. Qi is a Chinese word which means โ€œair energy flow.โ€ This word is usually pronounced as โ€œchee.โ€ The Wireless Power Consortium (WPC) developed Qi in 2008. Also, this standard was primarily developed to transmit inductive electrical power over about 1.6 inches.

In 2009, the WPC published the Qi low-power specification. The WPC worked on expanding the specification of the medium power.

System Overview

FULL PCB MANUFACTURING Quote

Furthermore, a Qi system includes:

  • Power conversion
  • Base station
  • Communication
  • Mobile devices

Power conversion

The base station has a transmitter which features a power conversion unit. The power conversion unit helps in converting electrical  power to wireless power. The receiver in phones has a power pick-up unit that helps to convert back wireless power signal to electrical power.

Base station

This comprises a power transmitter that has a transmitting coil. The transmitting coil produces an oscillating magnetic field. Also, the base stations comprise flat surfaces where you can place multiple devices.

Communication

The control and communication units are in power receivers and there is a technique known as modulation. Also, the receiver in the device switches the modulation capacitor or modulation resistor to modulate the load. Furthermore, the transmitter present in the base station senses primary coil voltage or primary coil current to demodulate reflected load.

Mobile devices

Mobile devices consume inductive power. Also, these devices can be tablets or smartphones. They have a receiver coil that features a power receiver. However, the receiver in the devices provides the battery power. Control and communication units are available in power receivers.

How does it work?

An electromagnetic field transmits energy between two objects. This is similar to the magnetic induction technology in physics. This same method is what inductive charging integrates. As it was earlier discussed, two coils are available. There is one coil in the receiver and the other coil in the transmitter. In the transmitter coil, you can generate a magnetic field  with an alternating current. Also, this magnetic field helps to induce voltage.

In reality, the receiver in the phone gets power from the electromagnetic field and then transforms it into electrical current. This will help to charge the battery. There are some mobile device manufacturers that are integrating this standard. These manufacturers include Nokia, Sony, LG Electronics, Asus, and Motorola Mobility among others. All devices having the Qi logo are compatible with wireless chargers.

How to Align the Coils

There are two ways to align the receiving and transmitting coil to ensure power transfer.

Free positioning

This method requires mobile devices shouldnโ€™t be placed on a particular position on the surface of the base station. Also, you donโ€™t need to align the coil directly. However, this method allows the integration of several transmitting coils at the location of the receiving coils. Therefore, it can produce a magnetic field and charge batteries inductively.

Guided positioning

You have to place the mobile device on a particular position on the base stationโ€™s surface. Also, this is because the receiver coil is in the mobile device while the transmitter coil is in the base station.

Modes of Wireless Charging

There are two modes of charging Qi receivers. These are resonant mode and inductive mode. Also, the transmitter determines the operation mode.

Inductive mode

This mode considers tightly-coupled systems for inductive charging. To achieve the best outcome, the transmitter should function at a frequency that differs slightly from the resonant frequency. Also, this mode limits the distance between receiver and transmitter to a few millimeters. Furthermore, you can achieve high power efficiency with these tightly-coupled systems.

The coils are tightly coupled when the coils have similar size and their distance is less than their diameters.

Resonant mode

Charging occurs in resonant mode when the system features loosely-coupled coils. Also, there is a decrease in the magnetic coupling between coils when the distance between the receiver and the transmitter  coils is more than their coil diameters.

Which is better: resonant mode or inductive mode?

Tightly-coupled system is ideal for heat-sensitive applications since it has low heat production and high power transfer. Therefore, heat-sensitive devices like smartphones will benefit from this system. However, the downside of tightly coupled coils is that they are very sensitive to misalignment.

On the loosely-coupled system transfers power efficiently. Such type of system is ideal for applications that feature electromotive force or tight electromagnetic induction. Above all, your needs determine the type of mode to choose.

Qi Charging power

Qi wireless charging can deliver about 5 watts at the receiver output. On the other hand, with medium power, Qi charging can deliver about 120 watts. Furthermore, the relationship between the receiver and transmitter should occur during charging. Also, without interoperable communication, the charging process wonโ€™t commence.

When compared to traditional charging, you will realize wireless charging is slower. However, wireless charging is harmless to humans since it doesnโ€™t emit non-ionizing radiation. Also, this makes it environmentally friendly.

Drawbacks of Wireless Charging

Above all, wireless charging provides a convenient way to charge your phone and other devices. Also, this charging method gives you a free cable environment. You donโ€™t need to worry about cables or wires in your space.

Also, wireless charging offers several benefits. Due to these benefits, there are several phone accessories compatible with wireless charging around us. Also, wireless charging is becoming more popular across industries and in our world in general.

Despite the benefits of wireless charging, there is only one major drawback. The major drawback of wireless chargers is that they donโ€™t perform efficiently like wired chargers. Also, these chargers tend to be slower than fast-charging cable. Although there are ways to prevent inefficiency in wireless charging if you take certain measures.

Distance is a crucial factor too in terms of efficiency and speed. When the receiver of your device is far away from the transmitter of the wireless charger, the charging rate will be very slow. In this scenario, the magnetic field will have to struggle to transfer power to the device. Also, the device has to be directly on the wireless charger for fast power transmission. If it stays at a few millimeters, the charging process may slow down.

This major drawback can easily be prevented. Since you now understand the basic principle behind wireless charging, then you should build a larger transmitter. Also, this may not be as simple as that. If you would be creating a bigger transmitter, this means your phoneโ€™s wireless charging receiver must be very large. With a large wireless charging receiver and a bigger transmitter, the charging rate will be faster.

Is Wireless Charging Fast Enough?

Wireless Charging pcba

If the wireless charging isnโ€™t as fast as when you plug a device directly in the cable, then how fast is wireless charging? Also, what are the things you should expect from the wireless charging device, and is there a way you can make the charging process faster?

First, there is a need to consider that the deviceโ€™s maximum charging speed is about 10 watts. The average is 10 watts, although you can find some chargers of 15 watts and stronger. Fast chargers are usually something else. Normally, fast chargers can offer10 to 65 watts making use of the Qi standard and Quick Charge Technology.

  However, for wireless charging, it finds it difficult keeping up with this speed level. Rather, working with a wireless charger will give some challenges. For example, the materials and physical design, which prevents efficient and proper charging.

Otherwise, its inner transmitting coil will work effectively without any issue. Consider it like this. There was a time when a wireless charger will not work using a phone case. However, these days, this is not a problem. Therefore, as wireless charging continues to gain wide recognition, the efficiency and speed of the wireless charger will keep getting better, regardless of the aligned coils

As of today, you can get different fast chargers that help you charge your device quickly and in no time. Though it isnโ€™t as fast as the direct cable, there are companies that offer wireless and fast chargers, which can reach 15 watts.  

What You Should Expect With Phone Cases and Wireless Chargers

Will wireless chargers work with a phone case? Of course, an accessory for wireless charging can also work with phone cases. Moreover, there are caveats and considerations that you must take note of before you buy a phone case.

Bulky cases have become better

For the beginners, the bulky cases may work against you with respect to wireless charging. This doesnโ€™t happen for all thick cases. At times, it becomes difficult for the thicker case materials to come in contact with the inductor of the wireless charger. Moreover, many brands have considered this and have designed thicker phone cases in a special way that ensures they are compatible with the wireless chargers.

Go for Plastics Rather than Aluminum Cases

Metal and Aluminum-backed phone cases could hinder your device from getting the required boost. Although they are robust and durable, the aluminum cases could disrupt the charging. Take note that one of the Iphone models discontinued its aluminum casing or shell to go for a glass backing. This allowed it to conduct a specific charge on the recent wiring charging accessories and devices.

Why MagSafe Phone Cases are Important?

For those who love the wireless charging abilities of a phone, the MagSafe phone cases provide an advantage. What exactly does the MagSafe phone case do? The compatible devices of MagSafe, whether a battery pack or phone case all have different magnets, which helps to snap to the internal coil of a phone for wireless charging.

Due to the fact that MagSafe magnets are usually designed to help snap in place, this makes sure that the phone doesnโ€™t slide off or stray from your wireless charging disc, platform, or whatever stand for wireless charging is provided. In addition, whenever a MagSafe phone case is paired with the wireless charger that is Qi-enabled, you will be able to achieve faster charge.

Unfortunately, just a few phones presently available offer the MagSafe internal coil. These include the Iphone 13 and Iphone 12 series. Let us hope that with time, MagSafe becomes the norm for Android and Apple phones. However, for now, these devices offer unique snapping. Until these, if any of these devices are in your possession, then check out the MagSafe phone cases.

Collection of Wireless Chargers

If you wish to have a wireless connection that is good, then there is a need to consider two accessories. These include a phone case that has been outlined already and a wireless charging accessory. There are companies that offer high-quality phone cases that are designed for connecting the wireless charging device easily to the wireless charger.

Moreover, it ensures a compatible and well-made wireless charger that helps in keeping the internal transmitter coil of your phone on target. You donโ€™t need to worry about your device going off by some millimeters or to fidget with it so as to position it the right way. This is just exactly what a very good wireless charger offers. Below is a wireless charger collection. Letโ€™s consider each of them in detail.

Power Discs

The power disks provide a round and flat pad which rests on a countertop, deskspace, and tabletop. You can place it wherever you please. With other designs, you will be able to add a colorful and beautiful touch and look to your space. Also, you will find the Twinkle design in this Power Disc collection showcasing your phone, as well as a fabric design that is grey in color for a minimal look.

Furthermore, operating the power discs is easy. All you need to do is to drop the device on the pad and then allow it to charge. Regarding charging speed, expect Samsungs and Apple devices to have a value of 10W and 7.5W respectively. This convenient light indicator letโ€™s you know that your device has been properly placed on the pad and it its charging.

In addition, it provides a USB-C port for other devices that you might have or the Android device of a family or friend.

Furthermore, an Apple Watch stand has a magnetic layer that helps in positioning the watch and ensuring that it charges effectively. In addition, every area of wireless charging is Qi-compatible and provides quick charging that can reach 15W.

Wired Charging vs Wireless Charging: Which Is Better?

Wireless Charging pcb BOARD

For some years now, people have been using wireless charging and every day, it keeps gaining more popularity. However, have you ever wondered why wireless charging has become so popular? Is it going to take the place of the traditional wired charging method? Letโ€™s consider why wireless charging will most likely substitute wired charging.

Reasons why Wireless Charging may Substitute Wired Charging

Explaining in a simple way, wireless charging indicates that your handset device can be dropped on your charging dock. It then charges without having to plug it in your phone. The process we just explained is much easier compared to wired charging. Letโ€™s consider the benefits that wireless charging have over wired charging.

You wonโ€™t have to handle cables compared to the wired charging

Just imagine this situation. You donโ€™t have to plug and unplug any cable whenever there is a need to charge your device. All you need to do is to drop your device on your charging pad, and then it begins to charge without you doing anything else. Furthermore, everything will look neat and elegant. Sure, you donโ€™t have to be worried about the location of your charger or cable. However, not all wires will be gone. The charging base will need a wire to connect to the power supply.

Reduces wear and tear on devices

As we have mentioned before, you donโ€™t need cables for wireless charging. USB ports are not needed either. This means no strain will be placed on the charging port of the phone, charging plug, and cable. In addition, completely dustproof and waterproof cables are possible.

It makes the simultaneous charging of multiple smartphones possible rather than taking different kinds of cables along with you

For people owning different phones, they need to carry different chargers and cables when traveling. However, if these devices can feature wireless charging, then the charging pad will become an option that fits all. In general, the wireless chargers and cell phones from different manufacturers usually comply with the standard of Qi wireless charging. Therefore, just one wireless charger will be able to charge all the Qi-enabled devices.

Transferring Power to your device is safer. This avoids you putting your data and safety at risk

In contrast to plugging a device in, the wireless charging method helps in transmitting power without touching the electrical connectors that are exposed. What this means is that it reduces the possibility of electric shocks and connection failure.

Lots of deaths and injuries are caused by not using Cellphones or cables properly while charging. This sounds scary, but it actually happens. However, wireless charging could be much safer because one you pick it up, it stops charging.

Also, there is a lesser risk linked with plugging inside public USB chargers. One issue with this is that these public hubs for charging could collect some personal data when you arenโ€™t aware. This is one good reason why you should use wireless charging.

Wireless Charging is very neat

Just a few wires can cause your table to become very messy. This also includes the risks of someone tripping over the cables. However, with wireless charging, you have everything arranged in order.

Why is Wireless Charging Not Yet Everywhere

Wireless charging is usually less efficient and slower compared to wired charging

It was discovered that Samsung Galaxy S6 has the ability to charge full within 1.48 hours if plugged and charged over a specific wired connection. However, wireless charging can take 3.01 hours, which is twice the time it takes for wired charging to complete the task.

Also, it was discovered that wireless charging can take additional time to top your phone up and it takes additional power to be able to  charge your device completely too.

Wireless charging can cause overheating for your phone, which can bring harm to your battery

Lots of discussions exist regarding the heat of a wireless charger bringing harm to your battery among those who have begun wireless charging of their phones. It has been revealed that wireless charging generates some waste heat. It could even cause overheating for your phone battery in contrast to the traditional cable charging.

A part of this wasted power then transforms into heat and the additional heat will result in more tear and wear on your battery. This causes the batteryโ€™s aging to speed up each time you expose the phone battery to very high temperatures.

The wireless charger is a bit expensive compared to the common cables

Visit Amazon, and check the prices for wireless chargers and cables. You will discover that the majority of cables are below $10. Wireless chargers on the other hand cost an additional $20 or less. This difference is quite large.

By now, you know how wireless charging works. You also know its benefits and drawbacks. ย Each passing day we see more people adopting this new charging method, and only time will tell if the corded method of charging will be completely abolished for this new method. Also, if working with the wireless charging method, make sure that your device is well fitted with the MagSafe magnetic component and also search for some compatible accessories as well.

Wireless charging has gradually gained popularity across several industries like manufacturing, automotive, and medical. Also, wireless charging is harmless to humans since it doesnโ€™t emit non-ionizing radiation. Individuals and companies are beginning to know more about wireless charging and how they can use them daily.

With much being discussed, we can boldly say that wireless charging will change a lot in the electronics industry. It will change how people perceive technology. Also, it intends to make things easier for people and the world at large.

CYUSB3014-BZXC: An Application-Specific Microcontroller with External Program Memory

Application-specific Microcontrollers (MCUs) are specific types of Microcontrollers used primarily for the processing of data in a single device.

Unlike a typical Microcontroller, it works extensively to combine as many resources as possible in the target device or application. These resources range from peripherals like UARTs, clocks and converters; the main processing unit, a Microcontroller (MCU); and different memory types, such as RAM, EEPROM, ROM and Flash.

Today, we discuss the CYUSB3014-BZXC application-specific Microcontroller with a special focus on the features.

How Does CYUSB3014-BZXC Work?

It is an application-specific Microcontroller, meaning that the use case is mostly for specified applications or devices. In this case, it is used with most consumer electronics, such as data acquisition devices, digital cameras and printers. It is also used with data loggers, scanners, industrial cameras, surveillance cameras, digital still cameras.

Important Information about the Series and Application

CYUSB3014-BZXC Microcontroller

CYUSB3014-BZXC belongs to the EZ-USB FX3 series of application-specific Microcontrollers (MCUs) by Infineon Technologies. It then supports the SuperSpeed USB Peripheral Controller, which doubles as the primary architecture.

Making the most out of the SuperSpeed USB Peripheral Controller involves the use of the EZ-USB FX3 Software Development Kit (SDK). Through this SDK, it becomes possible to maximize all that the controller has to offer.

Support for Multiple Interfaces

Besides the support for several peripherals, CYUSB3014-BZXC also supports multiple interfaces. The most popular ones are the JTAG Interface and the Slave FIFO Interface. The others are the UART Interface, the SPI Interface and the I2C Interfaces.

Below is a breakdown of how each of those interface work:

1. JTAG Interface

This is the interface used for connecting CYUSB3014-BZXC to the JTAG Debugger. It comprises standard five-pin interfaces, which are used for debugging firmware via the core on-chip-debug circuitry of CYUSB3014-BZXCโ€™s Central Processing Unit (CPU).

2. I2C Interface

This interface is not just compatible with the I2C Bus Specification Revision 3. It is also ideal when connecting the CYUSB3014-BZXC for operations with the I2C Master. Through this connection, the interface opens up the pathway for communicating with or connecting to the other slave I2C devices.

3. SPI Interface

This is the larger hub for more bit-sized transactions. Based on the Serial Peripherals Port, the SPI Master Interface can process transaction sizes up to 32 bits.

Worthy of mentioning is that it also supports a couple of other modes, most especially the Start-Stop Lock.

4. Watchdog Timer

Watchdog timers are in place to monitor the performances of Microcontrollers (MCUs). CYUSB3014-BZXC uses a 32-kHz watchdog timer clock input, which plays a relevant role in regulating the MCU and monitoring the overall performance.

For example, the timer runs on a 32-kHz clock, which may also be supplied via an external source on a dedicated FX3 pin.

In terms of the sleep mode, the watchdog timer automates the waking of the FZ-USB FX3 when on a Standby Mode.

The watchdog timer can also perform other functions, such as interrupting and resetting the ARM926EJ-S core.

5. Maximum Power Performance

CYUSB3014-BZXC derives the power performances from different peripherals. There are the I2C operation at the 1.2-volt to the 3.3-volt levels, and a combination of the UART, SPI and I2C power operations running between the 1.8-volt and 3.3-volt regions. That is for the independent power domains for both the Input and Output (I/O) pins and the core.

On the other hand, we have the low-power options facilitated via the less than 60 ยตA with VBATT on. It also offers the low-power through the 20 ยตA with VBATT off.

The SuperSpeed Explorer Board

FULL PCB MANUFACTURING Quote

CYUSB3014-BZXC also supports the SuperSpeed Explorer Board; a board dedicated to the rapid prototyping of the applications.

The components of the board include but are not limited to:

6. CPLD Board

This board is used to test the concept or design, before starting the initial phases of the boardโ€™s development.

7. Adapter Boards

These are dedicated boards meant for the development of Field Programmable Gate Arrays (FPGAs) and Xilinx circuit boards.

8. Adapter Board

CYUSB3014-BZXC also has another adapter board, but this time, it is to be used for video development.

What You Need to Know about CYUSB3014-BZXCโ€™s Low-Power Modes

The low-power modes used here are essentially designed to reduce the power consumption on this microcontroller. To do that effectively, the manufacturer incorporated several low-power modes, with each functioning differently.

Here are some of the low-power modes and how they contribute to CYUSB3014-BZXCโ€™s low-power consumption:

9. Core Power Down Mode

Also called the L4 power mode, the Core Power Down Mode is where the โ€œcoreโ€ of CYUSB3014-BZXCโ€™s power lies. Here, individual activation and deactivation (turning on and off) of the different power modes is activated.

Note that when the core power down mode is active, the combination of the Program RAM, buffer memory and configuration registers wouldnโ€™t maintain their original states.

To reactivate these respective states, the firmware must be reloaded as soon as the Core Power Down Mode is turned off.

10. Suspend Mode

This low-power mode works with the USB 3.0 PHY Enablement. It works by allowing the I/Os to maintain their previous states, but on the condition that the other power modes (with the exception of the wakeup source) must be turned on and off, as the case might be.

Although the original states of the internal RAM, configuration registers, and the buffer memory are maintained; the pending register configurations must be completed. This is because the activation of the Suspend Mode might wipe off the current data or configurations in the registers.

But when these configurations are saved, the FX3 can safely enter the Suspend Mode.

11. Standby Mode

In the Standby Mode, CYUSB3014-BZXC protects the configurations of the data RAM content and that of the previous register settings.

However, it doesnโ€™t guarantee a preservation of the configurations in the respective data paths. That is why it is imperative to read and store the data pathsโ€™ information before putting the CYUSB3014-BZXC Microcontroller in the Standby Mode.

Final Thoughts

CYUSB3014-BZXC is a specified Microcontroller, delegated for use when configuring specific applications. Therefore, maximize the attributes by considering the different power modes before using.

BLL9G1214L-600U is an Ideal LDMOS Power Transistor for L-Band Radar Applications

BLL9G1214L-600U

BLL9G1214L-600U is a Laterally-Diffused Metal-Oxide Semiconductor (LDMOS), designed for use with the L-band radar applications. The most outstanding attribute is its 600-watt power transistor capability, enabling the increment of the target applicationsโ€™ frequency range up to 1.4 Gigahertz (GHz).

The Signal Switching Capabilities

BLL9G1214L-600U can switch signals because it is one of the devices categorized under RF Transistors, MOSFETs and FETs.

By design, the FETs, RF Transistors and MOSFETs are families of devices meant to regulate current flow through devices. These devices help to control the current flow, using an electric field.

LDMOS, being of those devices, is used in BLL9G1214L-600U to switch and amplify signal and power flow through the L-band radar applications.

ESD Protection

Device protection with Electrostatic Discharge (ESD) is offered to help increase BLL9G1214L-600Uโ€™s security. In that case, we are looking at a combined protection via the Air Gap Discharge and the Contact Discharge.

Both discharge variants aim at checking the discharge or removal of pulse from the Device Under Test (DUT).

BLL9G1214L-600Uโ€™s ESD protection is based on an integrated dual-sided protection design, which helps keep the semiconductor active, even when in off-state isolation.

L-Band Optimization

Ampleon USA

BLL9G1214L-600U is optimized for the L-band applications and there are some upsides to that. L-band is a type of pulsed radar by Ampleon USA Incorporated. The companyโ€™s optimization for this is to enable the amplification of the lined-up devices (in this case, the BLL9G1214L-600U) for pulsed operations over the entire frequency band.

To that end, BLL9G1214L-600Uโ€™s L-band operation is designed to go above the 3500 MHz frequency band. Doing so makes the semiconductor ideal for the high-end pulsed radar applications.

Excellent Ruggedness

BLL9G1214L-600U is also a rugged or robust semiconductor, capable of withstanding pressure. The information in the datasheet shows that it can withstand a load mismatch up to VSWR = 10:1.

This load mismatching can be further extended across the entire class-AB classes or specifications.

Target Applications

BLL9G1214L-600U is the ideal semiconductor and LDMOS for the pulsed radar devices/applications, which are based on the next-generation LDMOS and GaN technologies.

The selection of these devices is based on the longevity and durability of the target applications.

Examples of the supported applications are:

  • Cooking and defrosting devices/appliances.
  • Aerospace and defense applications, such as military communications, radar and electronic countermeasure devices.
  • Broadcast devices, including UHF/D-TV
  • Industrial, scientific and medical applications, comprising particle accelerators, and industrial heating appliances.

BLL9G1214L-600U LDMOS Advantages

Is there any benefit to using the Laterally-Diffused Metal-Oxide Semiconductor (LDMOS) structure for BLL9G1214L-600U? Apparently, there are a couple of reasons why it is relevant.

Here are some of the notable benefits:

1. Excellent Class-AB Operations

BLL9G1214L-600U proves to be a better choice for Class-AB operations and that is for no other reason than the higher load mismatching support.

In light of that, it is further used in the design of linear amplifiers, especially for the ones requiring improved efficiency and higher gain.

2. Idealistic Use with High-Crest Systems and Broadbands

FULL PCB MANUFACTURING Quote

BLL9G1214L-600U is also an ideal LDMOS for use with high-crest systems, such as WCDMA and CDMA. The usage in this case is because of the higher PAPR capabilities.

On the other hand, it performs excellently with the broadband applications, especially with the applications below 1 Gigahertz (GHz).

3. Higher Operations and Ideal for High-End Applications

BLL9G1214L-600U is also ideally used with the high-end or cost-effective Power Amplifier solutions.

The operations are also higher, as the semiconductor can clock up to 2.2 Gigahertz (GHz).

The performance is also bolstered by the delivery of the highest power rating up to 1.5 Gigahertz (GHz).

Drawbacks to BLL9G1214L-600Uโ€™s LDMOS

Although the Laterally-Diffused Metal-Oxide Semiconductor (LDMOS) structure used with BLL9G1214L-600U is ideal, it can also have some disadvantages.

These are some of the common drawbacks:

1. Long-Term Reliability is Technical

The chances of getting long-term durability out of any of the supported applications relies on some technical factors. For one, BLL9G1214L-600U deals more with gold top metallization, which is one of the major ways to keep the applications for the long-term usage.

2. Unfavorable Performance in Some Cases

BLL9G1214L-600Uโ€™s LDMOS doesnโ€™t so well in all scenarios. In some cases (when dealing with higher RF energy frequencies), the performance is not as prominent as that of GaN is.

LDMOS vs GaN: The Major Differences

The major difference between LDMOS and GaN is that the latter offers advanced or higher RF energy frequencies. In that case, you want to prioritize using GaN instead of LDMOS.

GaN also gains a considerable edge over LDMOS in the area of covering higher bandwidths.

Those two are the major upsides that the GaN has over LDMOS in the aspect of semiconductor development/process technology.

Now to how LDMOS compares against the GaN process technology. Here are some of the comparable benefits:

LDMOS Offers Lower Costs

High-end applications are costly already and costs can add up quickly when the components used are considered too. LDMOS appears to be a cost-effective process technology because of the low-cost approach to L-band radar applicationsโ€™ design.

In this instance, it doesnโ€™t use up much resources at the final-stage of the design, unlike the GaN, which does use drivers, whole line-ups and pre-drivers at this stage.

Besides, LDMOS are continually exploring options to minimize the costs and make it a better alternative to GaN and other types of process technologies for semiconductor devices.

LDMOS has Widespread Adoptions

Any process technology that gains relevance is subject to gaining widespread adoptions. That is what sets LDMOS apart from GaN.

Most digital circuit consumers prefer it for reasons ranging from the series of node generations, long-term performance and reliability; and the continuous improvements in the area of application-specific reliability.

Final Thoughts

To put it all together, BLL9G1214L-600Uโ€™s LDMOS is an ideal process technology for making the most-optimized, cost-effective and reliable L-band radar applications.

ATMEGA168PA-MU: A Low-Power CMOS Microcontroller

ATMEGA168PA-MU

ATMEGA168PA-MU is a low-power microcontroller, powered by the CMOS technology. Manufactured by Microchip Technology, it enables the execution of instructions in a single clock style.

In this blog post, you are going to find out how it works, as well as some of the technical properties.

What is ATMEGA168PA-MU?

It is a Microcontroller (MCU) manufactured by Microchip Technology. At the core of the functionalities is the basis on the AVR-enhanced RISC architecture.

If you are looking to get a Microcontroller (MCU) that powers a variety of applications, this is one of the right ones to get.

Read on to find out more about how it works:

Power Optimization Capabilities

atmega168

Optimizing or finding a balance between power and the performance of the circuit board is at the core of the ATMEGA168PA-MUโ€™s operations.

Finding the power optimization balance is offered via ATMEGA168PA-MUโ€™s Million Instructions Per Second (MIPS) per Megahertz (MHz). The power consumption is further reduced in the process through the deviceโ€™s achievement of CPU through this process.

This power consumption balance process is one of the reasons why ATMEGA168PA-MU is flexible for the circuit board designer to optimize the Microcontroller (MCU) for power and speed.

Data Retention Capabilities

The default function of Microcontrollers (MCUs) is to facilitate the repetitive execution of a predefined series of tasks. To that end, digital circuit designers leverage ATMEGA168PA-MUโ€™s data retention capabilities to enhance the information or data processed through it.

ATMEGA168PA-MUโ€™s data retention capability is pegged at 20 years and operating at 85-degree Celsius. It also retains the data at 25-degree Celsius per 100 years.

Non-Volatile Memory Capabilities

The data retention is one aspect of the ATMEGA168PA-MUโ€™s memory or data capabilities. The other is the non-volatile memory capabilities segments, with higher endurance rates.

The capabilities in this case include:

  • 512/1K/1K/2Kbytes of Internal SRAM
  • 4/8/32Kbytes of In-System Self-Programmable Flash Program Memory.
  • Write Erase Cycles of 10,000 Flash and 100,000 of EEPROM
  • 256/512/512/1Kbytes of EEPROM.

ATMEGA168PA-MU also has an Optional Boot Code Section with a set of Independent Lock Bits.

This Optional Boot Code has a wide range of components, including true read-while-write operation and in-system programming by on-chip boot program.

ATMEGA168PA-MU has QTouch Library Support

ATMEGA168PA-MU supports a wide range of library facilities. These facilities help bolster the configuration of the target devices.

On the list of supported components or peripherals are:

  • Support for up to 64 sense channels.
  • Sliders, capacitive touch buttons and wheels.
  • QTouch and QMatrix acquisitions.

ATMEGA168PA-MU Uses an Advanced Microcontroller Architecture

The architecture used by a Microcontroller (MCU) plays an important role in how it turns out, in terms of the effectiveness. In ATMEGA168PA-MUโ€™s case, it is powered by the robust and advanced AVR RISC architecture.

This architecture is all-around solid, in the sense that it helps the digital circuit designer to maximize the configuration peripherals to make the most out of the microcontroller.

The following are some of the peripherals or cosmetics of the ATMEGA168PA-MU AVR RISC architecture:

1. Power Balance

The power consumption and balance capabilities of ATMEGA168PA-MU is bolstered via the Million Instructions Per Second (MIPS) per Megahertz (MHz) process. This does not only reduce the power consumption capabilities of the microcontroller, but also ensures that the processing speed is balanced in the process.

Therefore, you are leveraging both the power consumption capabilities and the processing speed to get the most out of both worlds.

With the MIPS capabilities, you can be sure that the ATMEGA168PA-MU can attain up to 20 MIPS throughput at 20 Megahertz (MHz).

2. Stack Pointer for Data Retention

Retaining data in the ATMEGA168PA-MU is not limited to the MIPS. It can also be retained with the Status Pointer. The Stack is mainly used to store temporary data, that is, data that isnโ€™t needed at the time.

The Stack Pointer is also used to store the local variables and for storing the return addresses, especially after the subroutine calls and the interrupts.

However, the Stack Pointer Register is mainly implemented when the memory begins to expand. The implementation helps to cater for the growing numbers of memories in the target device.

3. Excellent Power Management

FULL PCB MANUFACTURING Quote

Managing power is also an important criterion when choosing a Microcontroller (MCU) and that is what ATMEGA168PA-MU offers.

The power management solution offered here includes the sleep modes. The sleep modes are integrated to help the application shut down or turn off, especially by turning off the unused modules in the ATMEGA168PA-MU Microcontroller (MCU).

By shutting down the unused modules, ATMEGA168PA-MU is now able to conserve more power.

4. Brown-out Detector (BOD)

Saving power, current or energy in ATMEGA168PA-MU is not limited to the primary sleep modes. It can also be managed with the Brown-out Detector (BOD).

The detector works by monitoring the power supply of ATMEGA168PA-MU, especially when it has been put to sleep. The monitoring focuses on the sleep modes and how they adapt in those modes.

The Brown-out Detector (BOD) furthers disables when put in operation in some sleep modes. The disabling helps to save more power for ATMEGA168PA-MU.

5. Tailored Sleep Modes

ATMEGA168PA-MUโ€™s AVR-enhanced RISC architecture doesnโ€™t only provide the architecture for the Microcontroller (MCU)โ€™s operations. It also provides customizable sleep modes.

For example, the AVR allows for the customization or re-optimization of the sleep modes, as per the application or target deviceโ€™s requirements. That way, the consumer electronics can be fine-tuned and put in the right sleep mode.

6. Idle Mode

Putting the ATMEGA168PA-MU Microcontroller (MCU) in a sleep mode might impact how much it operates. For instance, most of the components or functions wouldnโ€™t be active after the mode has been enabled.

Therefore, using the Idle Mode proves to be a better option. In this case, it allows the ATMEGA168PA-MU MCU to operate in some ways, rather than having a complete shutdown.

For example, while in the Idle Mode, ATMEGA168PA-MU may be able to keep the interrupt system, the 2-wire Serial Interface and the Watchdog active. It can also turn off the CPU, but allow the following to be active:

  • USART Transmit Complete interrupts.
  • Analog Comparator
  • Timer Overflow
  • SPI
  • Timer/Counters
