What is Xilinx XA3S100E-4VQG100I ?

Building a new circuit design can be fun and exciting. However, one of the most daunting tasks of the process is choosing the right board.

With many available options in the market, the decision-making process can be a little difficult, especially if you are a newbie. In this case, knowing about the Xilinx XA3S100E-4VQG100I can be helpful. It’s one of the top board options today, and it might just be what you are looking for.

What is AN FPGA Used For?

Before discussing the specifications and attributes of the Xilinx XA3S100E-4VQG100I, you first need to understand what a Field Programmable Gate Array or FPGA is. So, what exactly is it?

It’s an integrated circuit that is programmable by its users after its manufacturing. These contain logic elements and adaptive logic modules connected using programmable interconnects. These then create a physical array of logic gates customizable to perform computing tasks.

FPGAs are different from Central Processing Units (CPU) or other types of microcontrollers. This is because CPUs and microcontrollers have set configurations that manufacturers seal. In short, you will be unable to modify them.

Xilinx XA3S100E-4VQG100I Overview

Here’s a closer look at the attributes and features of the Xilinx XA3S100E-4VQG100I:

Physical Attribute

Thin Quad Flat Package

The Xilinx XA3S100E-4VQG100I is a Thin Quad Flat Package (TQFP).

This is similar to Quad Flat Package (QFP) in a way that it has a “gull-wing” extending on all its sides. The socketing for this type of package is a bit rare. At the same time, you can use through-hole mounting with it.

TQFP packages, in particular, have the same benefits as QFT. The only difference is that it is way thinner. Compared to regular QFP, which are between 2.0 to 3.88 mm thick, TQFP package thickness can range between 1 mm to 1.4 mm thick.

In addition, since it’s a TQFP package, it can address issues such as die shrink programs, increasing board density, and portability.

Surface Mount

This device can be placed or mounted directly onto the PCB surface. These are preferred because they are more compact compared to wired elements.

Technical Specifications

100 Degrees Celsius Max Operating Temperature

This device can withstand temperatures up to 100 degrees celsius. This is a fairly decent maximum operating temperature for a device like this.

However, it does not mean that if you use it in a setting beyond the maximum temperature, then it will be destroyed. It’s just that its performance can be significantly affected, and there’s also a high chance that it can sustain damage. Nevertheless, this max operating system is okay for moderate users.

On the other hand, its minimum operating temperature is -40 degrees celsius. This means that it can operate in a cold environment without any problem. So, if you live in colder areas, this can still be a reliable board which is why it’s worth considering.

9 kB RAM Size

The Xilinx XA3S100E-4VQG100I has a 9 kB RAM size. The RAM size you need depends on what your application requires. This means you may or may not need a bigger or smaller RAM size.

4 Speed Grade

FPGA speed grade refers to the maximum frequency that its flop can run. Usually, the speed grade of an FPGA can be revealed using a magnifying glass. But, this one says that its speed grade is 4 based on what’s indicated by the manufacturer.

240 Logic Blocks

Logic Blocks, also known as Configurable Logic Blocks are fundamental components of an FPGA. Engineers can configure it to provide reconfigurable logical gates. The Xilinx XA3S100E-4VQG100I, in particular, has 240 logic blocks.

2160 Cells

There are several cells in an FPGA. Every cell is configurable to implement a particular set of functions. Every cell has a set number of output and input. For the Xilinx XA3S100E-4VQG100I, the number of configurable cells it contains is 2160.

1.2 V Operating Supply

FPGA devices are usually used to transfer input voltage. These are mostly from a DC bus supplied by an SMPS that ranges between 5V to 12.


This device is ROHS Compliant. This means that the difficult to dispose substances or hazardous material used in making the device is below the set maximum.

Although RoHS compliance is not a federal requirement, knowing that the device you are using follows its standard can give you peace of mind. At the same time, these products are also much better for the environment since they contain little to no hazardous materials.

Who Will Benefit This Product?

Devices such as Xilinx XA3S100E-4VQG100I are used in various industries. This include:

  • Military

Military equipment such as electronic warfare systems, radars, and sensors utilize FPGA devices such as Xilinx XA3S100E-4VQG100I.

The automotive industry can benefit from an FPGA device like Xilinx XA3S100E-4VQG100I. Many designers like using these types of devices for vision processing applications that need high-level processing.

Other Important Information

Xilinx has multiple brands worldwide. Because of this, some distributors might use alternate names for the brand, which can be confusing.

With this in mind, here are some of its notable alternate names in case you want to buy from this brand:

  • XIL
  • XILI
  • XILX
  • XILL
  • XIL/97(B)
  • Xilinx Incorporate

Final Words

There you have it; those are everything that you need to know about the Xilinx XA3S100E-4VQG100I.

Choosing the right FPGA is vital in a circuit build. This is why it’s important to choose the one that you will be using carefully. Based on the information mentioned above, the Xilinx XA3S100E-4VQG100I can be a decent choice.

However, by the end of the day, you need to consider what type of application you are working on when it comes to choosing an FPGA. This way, you won’t find it difficult to find the right fit for your needs.
