The Digilent Cora Z7 is a ready-to-use, low-cost, and easily embeddable development platform designed around the powerful Zynq-7000
All-Programmable System-on-Chip (APSoC) from Xilinx. The Zynq-7000 architecture tightly integrates a single or dual core 667MHz ARM
Cortex-A9 processor with a Xilinx 7-series FPGA. This pairing grants the ability to surround the processor with a unique set of software
defined peripherals and controllers, tailored for the target application.
The Cora Z7’s wide array of hardware interfaces, from a 1Gbps Ethernet PHY to analog-to-digital converters and general-purpose
input/output pins, make it an ideal platform for the development of a vast variety of embedded applications. The small form factor and
mounting holes make the Cora Z7 ready to be used as one component of a larger solution. The on-board SD Card slot, Ethernet, and
Power solution allow the Cora Z7 to operate independently of a host computer.
