Product Description

The Nexys provides a reliable, all-in-one circuit development platform for engineers at all levels. It can be used to implement designs ranging from simple logic circuits to complex digital systems, without needing any other components. All signals are ESD and short-circuit protected, ensuring a long operating life in any environment. 

The Nexys features a 400K-gate Spartan®-3 FPGA with hardware multipliers and high-speed dual-port memory arrays. Its large external memory arrays (4MB ROM/16MB RAM), collection of useful I/O devices, and numerous ports make the Nexys the perfect platform for working with embedded cores like MicroBlaze™ from Xilinx®.

The Nexys is fully compatible with all versions of the Xilinx ISE® tools, including the free WebPACK™. The Nexys is powered via the USB port and it ships with the appropriate USB cable, so designs can be implemented immediately with no hidden costs. Now every student can own a state of the art development system for less than the cost of a textbook.
