Part 3: FPGA
The FPGA model used by the AX301 development board is
EP4CE6F17C8, which belongs to ALTERA's Cyclone IV. This model is a BGA
package with 256 pins. The definition of FPGA pins is explained again. Many
people use FPGAs that are non-BGA packages, such as 144-pin, 208-pin
FPGA chips. Their pin definitions are composed of numbers, such as 1 to 144,
1 to 208, and so on. When we use a BGA packaged chip, the pin names
become
l numbers
, such as E3, G3, etc. Therefore, when reading the
schematic diagram, the l numbers in this form represent the FPGA Pin.
Having said this, let's look at the functions of various parts related to FPGA.
Figure 3-1 is the FPGA chip used in the development board.
