Part 2: AC7K325 Core Board
Part 2.1: AC7K325 Core Board Introduction
AC7K325 (core board model, the same below) core board, FPGA chip is
based on XC7K325TFFG900 of XILINX company XC7K325 series. The core
board uses 4 Micron 512MB DDR3 chips MT41J256M16HA-125, with a total
capacity of 2GB. In addition, a 128MBit QSPI FLASH is also integrated on the
core board, which is used to start storage configuration and system files.
The 4 board-to-board connectors of this core board extend 276 IOs, of
which the level of 92 IOs of BANK17 and BANK18 can be modified by replacing
the LDO chip on the core board to meet the requirements of users without level
interfaces. In addition, the core board has also expanded 16 pairs of
high-speed transceiver GTX interfaces. For users who need a lot of IO, this
core board will be a good choice. Moreover, in the IO connection part, the
wiring between the FPGA chip and the interface has been processed with
equal length and differential processing, and the size of the core board is only
80*60 (mm), which is very suitable for secondary development.
