Part 1: FPGA Development Board Introduction

The entire structure of the AX7A200 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 FPGA + 2 DDR3 + QSPI FLASH,

which undertakes the functions of high-speed data processing and storage of

FPGA, high-speed data reading and writing between FPGA and two DDR3s,

data bit width is 32 bits, and the bandwidth of the whole system is up to 25Gb.

/s(800M*32bit); The two DDR3 capacities are up to 8Gbit, which meets the

need for high buffers during data processing. The selected FPGA is the

XC7A200T chip of XILINX's ARTIX-7 series, in BGA 484 package. The

communication frequency between the XC7A200T and DDR3 reaches 400Mhz

and the data rate is 800Mhz, which fully meets the needs of high-speed

multi-channel data processing. In addition, the XC7A200T FPGA features four

GTP high-speed transceivers with speeds up to 6.6Gb/s per channel, making it

ideal for fiber-optic communications and PCIe data communications.

The AX7A200 carrier board expands its rich peripheral interface, including

1 PCIex2 interface, 2 SFP Interface, 1 HDMI Output interface, 1 HDMI Input

interface, 1 Uart Interface, 1 Gigabit Ethernet interfaces,1 SD card slot, 2-way

40-pin expansion header, some buttons, LED and EEPROM circuit.

Part 2: AC7A200 Core Board

Part 2.1: AC7A200 Core Board Introduction

AC7A200 (core board model, the same below) FPGA core board, it is

based on XILINX's ARTIX-7 series 100T XC7A200T-2FBG484I. It is a

high-performance core board with high speed, high bandwidth and high

capacity. It is suitable for high-speed data communication, video image

processing, high-speed data acquisition etc.

This AC7A200 core board uses two pieces of MICRON's

MT41J256M16HA-125 DDR3 chip, each DDR has a capacity of 4Gbit; two

DDR chips are combined into a 32-bit data bus width, and the read/write data

bandwidth between FPGA and DDR3 is up to 25Gb; such a configuration can

meet the needs of high bandwidth data processing.

The AC7A200 core board expands 180 standard IO ports of 3.3V level, 15

standard IO ports of 1.5V level, and 4 pairs of GTP high speed RX/TX

differential signals. For users who need a lot of IO, this core board will be a

good choice. Moreover, the routing between the FPGA chip and the interface is

equal length and differential processing, and the core board size is only 2.36

inch *2.36 inch, which is very suitable for secondary development.
