This development board uses Xilinx’s zynq7000 series chip, model XC7Z030-2FFG676I, 676-pin FPGA package.

This chip can be divided into a PS (Processor System) part and a PL (Programmable Logic) part. On the PE7030 development board, the PS and PL sections of the XC7Z030 are both equipped with a wealth of external interfaces and devices for convenience use and functional verification.

In addition, as always, the USB Cable downloader circuit is integrated on the development board. Users only need to use a USB cable to download and debug the development board.

The main parameters of the PS system part are as follows:

– ARM dual-core CortexA9 based application processor, ARM-v7 architecture up to 1GHz

– 32KB level 1 instruction and data cache per CPU, two CPU share 512KB level 2 cache

– On-chip boot ROM and 256KB on-chip RAM

– External storage interface, support 16/32-bit DDR2, DDR3 interface

– Two Gigabit network interface cards support: divergent-aggregate DMA, GMII, RGMII, SGMII interface

– Two USB2.0 OTG interfaces, each supporting up to 12 nodes

– Two CAN2.0B bus interfaces

– Two SD card, SDIO, MMC compatible controllers

– Two SPIs, two UARTs, and two I2C interfaces

– 4 groups of 32-bit GPIO, 54 (32+22) bits as PS system I/O, 64 bits connected to PL
