Part 1: AC7Z100B Core Board Introduction
AC7Z100B (core board model, the same below) FPGA core board, ZYNQ
chip is based on XC7Z100-2FFG900 of XILINX company ZYNQ7000 series.
The ZYNQ chip's PS system integrates two ARM CortexTM-A9 processors,
AMBA® interconnects, internal memory, external memory interfaces and
peripherals. The FPGA of the ZYNQ chip contains a wealth of programmable
logic cells, DSP and internal RAM.

chips
MT41J256M16HA-125 for a total capacity of 4GB. Two DDR3s are mounted on
the PS and PL sides, respectively, which form a 32-bit bus width. The DDR3
SDRAM on the PS side can run at up to 533MHz (data rate 1066Mbps), and
the DDR3 SDRAM on the PL side can run at speeds up to 800MHz (data rate
1600Mbps). In addition, two 256MBit QSPI FLASH and 8GB eMMC FLASH
chips are integrated on the core board to boot the storage configuration and
system files.
In order to connect with the carrier board, the four board-to-board
connectors of the core board expand the USB interface, the Gigabit Ethernet
interface, the SD card interface and other remaining IO ports of the PS side;
and also extend the 8-pair high-speed transceiver GTX interface of the ZYNQ,
almost all IO ports (144) on the PL side. The level of IO of BANK12 and
BANK13 can be modified by replacing the LDO chip on the core board to meet
the requirements of different level interfaces of users. For users who need a lot
of IO, this core board will be a good choice. Moreover, the IO connection part,
the routing between the ZYNQ chip and the interface is equal length and
differential processing, and the core board size is only 80*60 (mm), which is
very suitable for secondary development.
