This ZYNQ7000 FPGA development platform adopts the core board +
carrier board mode, which is convenient for users to use the core board for
secondary development. The core board uses XILINX's Zynq7000 SOC chip
XC7Z100 solution, uses ARM+FPGA SOC technology to integrate dual-core
ARM Cortex-A9 and FPGA programmable logic on a single chip. In addition,
the core board contains 4 pieces of 2GB high-speed DDR3 SDRAM chips, 1
piece of 8GB eMMC memory chip and 1 piece of 256Mb QSPI FLASH chip.
In the design of carrier board, we have extended a wealth of interfaces for
users, such as a PCIex8 slot, 4 fiber interfaces, 2 Gigabit Ethernet interfaces, 4
USB2.0 HOST interfaces, 1 HDMI output interface, 1 HDMI input interface, 1
channel UART serial interface, 1 SD card interface, and 40-pin expansion
interface. It meets users' requirements for high-speed data exchange, data
storage, video transmission processing and industrial control. It is a
"professional" ZYNQ development platform. For high-speed data transmission
and exchange, pre-verification and post-application of data processing is
possible. This product is very suitable for students, engineers and other groups
engaged in ZYNQ development.

Part 1: FPGA Development Board Introduction
The entire structure of the AX7Z100 FPGA development board is inherited
from our consistent core board + carrier board model. A high-speed inter-board
connector is used between the core board and the carrier board.
The core board is mainly composed of ZYNQ7100 + 4 DDR3 + eMMC +
QSPI FLASH. The ZYNQ7100 uses the Xilinx Zynq7000 series of chips, model
XC7Z100-2FFG900. The ZYNQ7100 chip can be divided into Processor
System (PS) and Programmable Logic (PL). On the PS and PL sides of the
ZYNQ7100 chip, two DDR3s are mounted, each with a DDR3 capacity of up to
512 Mbytes. The ARM system and the FPGA system can independently
process and store data. The PS-side 8GB eMMC FLASH memory chip and
512Mb QSPI FLASH are used to statically store ZYNQ's operating system, file
system and user data.
The AX7Z100 carrier board expands its rich peripheral interface, including
one PCIex8 slot, four SFP interfaces, two Gigabit Ethernet interfaces (one for
PS and one for PL), four USB2.0 HOST interfaces, one HDMI output interface,
one HDMI input interface, and one UART serial interface. 1 SD card interface,
40-pin expansion header and some buttons.

Part 2: AC7Z100 core board
Part 2.1: AC7Z100 core board Introduction
AC7Z100 (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.
The core board uses four Micron 512MB DDR3 chips
MT41J256M16HA-125 for a total capacity of 4GB. Two DDR3s are mounted on

ZYNQ FPGA Development Board AX7Z100 User Manual

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.

Part 2.4: QSPI Flash
The FPGA core board AC7Z100 is equipped with two 256MBit Quad-SPI
FLASH chips to form an 8-bit bandwidth data bus, the flash model is
W25Q256FVEI, which uses the 3.3V 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.

Table 2-4-1: QSPI FLASH Specification
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
2-4-1 shows the QSPI Flash in the schematic.
