XC9572XL-7VQG64I’s CPLD is Ideal for High-Performance Applications

It is generally believed that Field Programmable Gate Arrays (FPGAs) are one of the embedded or Integrated Circuits (ICs) with a mix of complicated and flexible design processes. However, it is not entirely true. There are some other embedded devices, such as CPLDs that function the same way.

One factor to look for when choosing an embedded device or IC is the target application. More of than not, the ICs are designed for use with the applications or devices that have a higher-performance requirement. If that is what you are looking for but not in the form of an FPGA, we would be delighted to introduce you to a CPLD.

What is a CPLD?

The full name is Complex Programmable Logic Device. From that, you can guess that these types of devices are “complex” or a “bit hard to configure.”

It is rightly so because a CPLD is first, optimized as a user-programmable device that can be leveraged to perform a wide range of complicated tasks, including information processing and several other logical operations.

The complexity of the CPLD’s functionality stems from the support, integration or incorporation of a higher functionality, in the form of a set of logic gates. These gates are then used to facilitate the device’s programmability.

Introducing XC9572XL-7VQG64I as a CPLD


There are several types of Complex Programmable Logic Devices (CPLDs), and from different manufacturers. XC9572XL-7VQG64I is a CPLD with support for a wide range of computing systems and pin counts.

In the subsequent paragraphs, you will find out more about this CPLD’s functionalities and the components that make it worth the while.

The Target is for High-Performance Applications

When we say “high-performance applications,” reference is being made to the applications that require a higher functional capacity. Worthy of mentioning here is that XC9572XL-7VQG64I’s CPLD is optimized for low-voltage applications, particularly those used in computing systems and leading-edge communication markets.

Improved CPLD Functions with Xilinx’s Innovative Product

A long time ago, the functionality of CPLDs was limited to the traditional process of analog sense amplifiers to boost the device’s performances.

However, all that has changed with the innovative product or architecture introduced by Xilinx, the manufacturer of the XC9572XL-7VQG64I CPLD. The name of this architecture is CoolRunnerTM-II CPLDs.

The manufacturer released it to offer better programming and optimization optics for the CPLDs. At the core of the CoolRunnerTM-II CPLDs’ functionality is the use of an “innovative all-digital core to achieve the same levels of performance at ultra-low power requirements.”

You will recall that we mentioned that the traditional design of a CPLD is to be used as an in-house programming platform for configurable devices. To that end, the CPLD typically involves the optimization of low-voltage applications that require higher performances.

However, the CoolRunnerTM-II CPLDs offer to deliver almost the same levels of performance (i.e., the high-performance and low-voltage requirements), irrespective of whether the optimization is to be done on only the ultra-low power applications.

Cross-Platform Design Support

Ordinarily, if we are to depend on the traditional format of optimizing CPLDs, we could have been looking at a one-sided model.

It is to the advantage of the new-generation configurable devices that the CoolRunnerTM-II CPLDs were released. With these types of CPLDs, it would now be possible to optimize the target applications across different facets.

For example, it allows for the use of the same CPLD architecture to configure both the low-power designs and the high-performance designs and in real-time.

The Generally-Combined Architecture

Even without the CoolRunnerTM-II CPLD, the XC9572XL-7VQG64I can function to a greater extent. According to Xilinx, the range of CPLDs it manufactures are optimized to comprise the following:

  • A bank of macrocells
  • The AND/OR array

On the one hand, the bank of macrocells are the “functional blocks” the perform either the sequential logic or combinational logic. These functional blocks are also designed to have or support added flexibility for either complement or true purposes. These blocks are usually laced along the varied feedback paths.

On the other hand, the AND/OR array is the second part of the traditional CPLD architecture. It works by performing a wide range of logic-centric functions.

Power Reduction Capabilities

XC9572XL-7VQG64I can conveniently cut down on the excessive power to be dissipated from the device. The power reduction capability is derived from the configuration of each of XC9572XL-7VQG64I’s macrocells to be used for the low-power mode.

While that is going against the default design of the CPLD for high-performance uses, it can help save power for the devices.

Besides, XC9572XL-7VQG64I can also cut down on excessive power usage by configuring the software to automatically delete the unused macrocells and product-terms.

XC9572XL-7VQG64I CPLD’s System Reliance is Impressive

You can count on the excellence of the XC9572XL-7VQG64I CPLD, because of the quality it offers. Included here is the Electrostatic Discharge (ESD) of 2,000V, the endurance rating that exceeds 10,000 erase cycles and the 20-year data retention capabilities.

Routing and Connection Capabilities

XC9572XL-7VQG64I is able to maintain a higher and more-connected CPLD architecture because of the innovative connection capabilities.

Enabled here are the implementation of bus-hold circuitry on all the user pin inputs, the in-system programmability and the superior pin routing and pin-locking enabled via the Fast CONNECTTM II Switch Matrix.

Benefits of XC9572XL-7VQG64I’s CPLD

There are several reasons why you should choose XC9572XL-7VQG64I as your preferred Complex Programmable Logic Device (CPLD). These are some of the benefits of doing so:

1. It has a Scalable Architecture

If XC9572XL-7VQG64I were to rely on the traditional use of “analog sense amplifiers,” it would likely take a lot of time before it scales the design process.

However, the replacement of these amplifiers with the CoolRunnerTM-II CPLDs is a good move in the right direction.

Among many other things, the CoolRunnerTM-II CPLDs allows for design scalability for both the high-performance and the low-power devices.

2. Feature Enhancements

The CoolRunnerTM-II CPLDs, being the main architecture that powers XC9572XL-7VQG64I, also opens up the devices for future, feature-rich enhancements. It also paves the way for the costs of manufacturing these devices to be minimal.


XC9572XL-7VQG64I is an innovative CPLD, powered by the CoolRunnerTM-II CPLDS’ architecture. It supports dual-configuration for both low-power and high-performance devices; aggressive cost reduction and a scalable CPLD architecture.
