Attributes of the Xilinx XA7A100T-1CSG324I FPGA
Here are some of the unique features of the Xilinx XA7A100T-1CSG324I Integrated Circuit (IC):
1. Operating Temperature
The temperature of an Integrated Circuit (IC) should not be too hot or too cold. In the case of the Xilinx XA7A100T-1CSG324I, its temperature falls within two (2) automotive temperature grades. These are:
I-Grade
For the I-Grade, the operating temperature of the board should be anywhere between 40-degree Celsius and 100-degree Celsius.
Q-Grade
Field Programmable Gate Arrays (FPGAs) that fall under the Xilinx XA Artix-7 Q-Grade fall under an operating temperature rating of 40-degree Celsius and 125-degree Celsius.
The Xilinx XA7A100T-1CSG324I falls under the I-Grade operating temperature rating. Besides, FPGAs under the Xilinx XA Artix-7 series meet the highest standards of automotive operating temperatures.
Input and Output (I/O)
Input and Output (I/O) in an FPGA refers to the physical structures on a circuit board that allow the designer to establish connection between the FPGA target and the other (external) devices in the electrical system.
The Input and Output (I/O) typically works by translating or transmitting either an analog or digital signal to or from a digital value. It is through this process that the FPGA target can be used to process the signals.
A total of 210 Input and Output (I/O) resources are available on the Xilinx XA7A100T-1CSG324I FPGA.
According to the specifications of the Xilinx XA Artix-7 series, the Input and Output (I/O) logic is configurable by either registration or combination. Either of these methods are supported by the Double Data Rate (DDR).
Also, delays can be implemented on the inputs. These delays are generally classified as IDELAY and can be delayed up to 32 increments, with the variables being 78 ps, 52 ps and 39 ps.

Tips on Choosing the Best Field Programmable Gate Array
Here are some tips on how to choose the best Field Programmable Gate Array (FPGA) for your next automotive design project:
1. Performance of the Circuit Board
One of the major considerations for choosing a Field Programmable Gate Array (FPGA) is the performance of the board. Ideally, manufacturers specify the functionalities of the board and this gives you an idea of what to expect from it, in terms of performance.
In the case of the Xilinx XA7A100T-1CSG324I, it is designed for high-end automotive applications. This is because of the improvement in the previous Xilinx Spartan series that lagged in per watt logic.
2. Number of I/Os in the Board
Another important factor to consider is the number of Input and Output (I/O) pins on the board. The higher the number, the higher the chances of integrating as many functionalities as possible on the board.
The Xilinx XA7A100T-1CSG324I has a total of 210 I/Os, meaning 210 openings for establishing connection between the FPGA target and the other devices in the electrical system.
3. Speed Grade
What is the speed grade of the Field Programmable Gate Array (FPGA)? The Xilinx XA7A100T-1CSG324I has a 2-speed grade.
By design, a speed grade is used to highlight the highest operating frequency of the board. It is also used to correlate the operation of the chip with the actual design of the board.
4. Device Migration
Let’s say that you purchased the Xilinx XA7A100T-1CSG324I, but for some reason, you want to upgrade. Not all Field Programmable Gate Arrays (FPGAs) support that. However, you are lucky to do this if you are using the Xilinx XA7A100T-1CSG324I, one of the boards from the Xilinx Artix-7 FPGA.
This series of FPGA from Xilinx offers a feature called Device Migration. The feature allows for upgrade of a Field Programmable Gate Array (FPGA) to a higher variant of the board.
To that end, this is one of the major ways you can derive maximum functionality from the board while saving costs you could attracted by purchasing a new board.
5. Clock Management
The management and optimization of the clock to function optimally is another important factor to consider when choosing an FPGA. The Xilinx XA7A100T-1CSG324I Integrated Circuit (IC) takes a cue from the excellent clock management architecture of the Xilinx Artix-7 series.
Each of the FPGAs in this series offers up to six (6) Clock Management Tiles (CMTs) that include a Phase-Locked Loop (PLL) and a Mixed-Mode Clock Manager (MMCM).
