Part 2: ACU4EV core board
Part 2.1: ACU4EV core board Introduction
ACU4EV (core board model, the same below) FPGA core board, ZYNQ
chip is based on XCZU4EV-1SFVC784I of XILINX company Zynq UltraScale+
MPSoCs EV Family.
This core board uses 5 Micron DDR4 chips MT40A512M16GE, of which 4
DDR4 chips are mounted on the PS side to form a 64-bit data bus bandwidth
and 4GB capacity. One DDR4 chip is mounted on the PL end, which is a 16-bit
data bus width and a capacity of 1GB. The highest operating speed of DDR4
SDRAM on the PS side can reach 1200MHz (data rate 2400Mbps), and the
highest operating speed of DDR4 SDRAM on the PL side can reach 1066MHz
(data rate 2132Mbps). In addition, a 256MBit QSPI FLASH and an 8GB eMMC
FLASH chip are also integrated on the core board to start storage configuration
and system files.
In order to connect with the carrier board, the four board-to-board
connectors of this core board expand the PS side USB2.0 interface, Gigabit
Ethernet interface, SD card interface and other remaining MIO ports; also
expand 4 pairs of PS MGT high-speed transceiver interface; and almost all IO
ports on the PL side (HP I/O: 96, HD I/O: 84). The wiring between the
XCZU4EV chip and the interface has been processed with equal length and
differential, and the core board size is only 3.15*2.36 (inch), which is very
suitable for secondary development.

Part 2.4: QSPI Flash
The FPGA core board ACU4EV is equipped with one 256MBit Quad-SPI
FLASH chip to form an 8-bit bandwidth data bus, the flash model is
MT25QU256ABA1EW9, which uses the 1.8V CMOS voltage standard. Due to
the non-volatile nature of QSPI FLASH, it can be used as a boot device for the
system to store the boot image of the system. These images mainly include
FPGA bit files, ARM application code, and other user data files. The specific
models and related parameters of QSPI FLASH are shown in Table 2-4-1.
