What to think of FPGA chip tube foot number

What is FPGA chip

FPGA chip is a programmable logic chip that can achieve different logical circuit functions by re -programming.It is usually used as a circuit design prototype construction, digital signal processing, and embedded system control.

Why do you know the FPGA chip tube foot number

Cyclone IV FPGA

When designing the FPGA, it is very important to understand the name and number of each foot, because they determine the method of chip connection to the peripheral.At the same time, if you need to program the FPGA, you need to understand the number of the tube.

Naming and number format of FPGA chip feet

The name of the FPGA chip foot is usually based on the JEDEC standard JESD97, and the name format is PXXX, where XXX indicates the number.

How to view FPGA chip tube foot number

Most FPGA chip manufacturers will provide a special pipe distribution table for engineers to view.In addition, you can also find a detailed description of the pipe foot number and the functions of each pin in the data manual of the FPGA chip.

Classification of FPGA chip foot number

The classification of FPGA chip tube feet is usually based on its functions, including input tube feet, output tube foot, clock tube foot and power/ground pipe foot.


Enter the number of the tube foot

The input foot usually starts with i or IO, and its pin number is usually a 3 -digit number.For example, I1, i2, i3, etc.

Number of the output tube foot

The output tube foot usually starts with O or IO, and its pin number is also a three -digit number.For example, O1, O2, O3, etc.

Number of clock tube feet

The clock tube foot usually begins with CLK or CLKX (x is a number), and its pin number is also a 3 -digit number.For example, CLK1, CLK2, CLK3, etc.


Number of power/ground tube foot

Power/ground pipe foot usually starts with V or GND, and its number is usually a 2 -digit number.For example, V1, V2, GND1, GND2, etc.


Mastering how to view the pin number of the FPGA chip is very important for the design of the FPGA chip.We should carefully study the data manual and pipe distribution table provided by the manufacturer to successfully complete the design of the FPGA chip.

Understanding the FPGA chip tube pin number is the basis for FPGA design, it will have an important impact on the correctness and completion efficiency of the design.
