Part 1: ACU5EV Core Board Introduction
ACU5EV (core board model, the same below) FPGA core board, ZYNQ
chip is based on XCZU5EV-2SFVC784I 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
XCZU5EV 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: ZYNQ Chip
The FPGA core board ACU5EV uses Xilinx's Zynq UltraScale+ MPSoCs
EV family chip, module XCZU5EV-2SFVC784I. The PS system of the ZU5EV
chip integrates 4 ARM Cortex™-A53 processors with a speed of up to 1.2Ghz
and supports Level 2 Cache; it also contains 2 Cortex-R5 processors with a
speed of up to 500Mhz
The ZU5EV chip supports 32-bit or 64-bit DDR4, LPDDR4, DDR3, DDR3L,
LPDDR3 memory chips, with rich high-speed interfaces on the PS side such as
PCIE Gen2, USB3.0, SATA 3.1, DisplayPort; it also supports USB2.0 , Gigabit
Ethernet, SD/SDIO, I2C, CAN, UART, GPIO and other interfaces. The PL end
contains a wealth of programmable logic units, DSP and internal RAM. .

Part 3: DDR4 DRAM
The ACU5EV core board is equipped with 5 Micron (Micron) 1GB DDR4
chips, model MT40A512M16LY-062E, 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 maximum operating speed of the DDR4 SDRAM on the PS side
can reach 1200MHz (data rate 2400Mbps), and the 4 DDR4 storage systems
are directly connected to the memory interface of the PS BANK504. The
highest operating speed of the DDR4 SDRAM on the PL side can reach
1066MHz (data rate 2133Mbps), and a piece of DDR4 is connected to the
BANK64 interface of the FPGA. The specific configuration of DDR4 SDRAM is
shown in Table 3-1 below:

Table 3-1: DDR4 SDRAM Configuration
The hardware design of DDR4 requires strict consideration of signal
integrity. We have fully considered the matching resistor/terminal resistance,
trace impedance control, and trace length control in circuit design and PCB
design to ensure high-speed and stable operation of DDR4.
The hardware connection of DDR4 SDRAM on the PS Side is shown in

Part 4: QSPI Flash
The FPGA core board ACU5EV 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 4-1.

QSPI FLASH is connected to the GPIO port of the BANK500 in the PS
section of the ZYNQ chip. In the system design, the GPIO port functions of
these PS ports need to be configured as the QSPI FLASH interface. Figure 4-1
shows the QSPI Flash in the schematic.

Part 5: eMMC Flash
The ACU5EV core board is equipped with a large-capacity 8GB eMMC
FLASH chip, the model is MTFC8GAKAJCN-4M, it supports the HS-MMC
interface of the JEDEC e-MMC V5.0 standard, and the level supports 1.8V or
3.3V. The data width of eMMC FLASH and ZYNQ connection is 8bit. Due to the
large-capacity and non-volatile characteristics of eMMC FLASH, it can be used
as a large-capacity storage device in the ZYNQ system, such as storing ARM
applications, system files and other user data files The specific models and
related parameters of eMMC FLASH are shown in Table 5-1.

Table 5-1: eMMC FLASH Specification
The eMMC FLASH is connected to the GPIO port of the BANK500 of the
PS part of the ZYNQ UltraScale+. In the system design, it is necessary to
configure the GPIO port function of the PS side as an EMMC interface. Figure
5-1 shows the part of eMMC Flash in the schematic diagram.

Part 6: Clock configuration
The core board provides reference clock and RTC real-time clock for PS
system and PL logic respectively, so that PS system and PL logic can work
independently. The schematic diagram of the clock circuit design is shown in
Figure 6-1:
Figure 6-1: Core Board Clock Source
PS System RTC Real Time Clock
The passive crystal Y2 on the core board provides a 32.768KHz real-time
clock source for the PS system. The crystal is connected to the PS_PADI_503
and PS_PADO_503 pins of BANK503 of the ZYNQ chip. The schematic
diagram is shown in Figure 6-2:
