Overview
Digilent’s Nexys circuit board is an integrated
circuit development platform based on a Xilinx
Spartan 3 FPGA. The Nexys board provides
large external memory arrays, a collection of
useful I/O devices, and numerous ports,
making it an ideal platform for experiments
with FPGA-based digital systems, including
embedded cores like Xilinx’s MicroBlaze.
The Nexys board is suitable for designs
ranging from simple logic circuits to complex
digital systems, without needing any other
components. All external signals are ESD and
short-circuit protected, ensuring a long
operating life in any environment.
The Nexys is fully compatible with all versions
of the Xilinx ISE tools, including the free
WebPack. Nexys features include:
200K-gate Xilinx XC3S200 FPGA with
500+MHz operation (400K and 1M gate
versions available)
USB2 port for FPGA configuration and
high-speed data transfers (using the free
Adept Suite Software)
USB-powered (batteries and/or wall-plug
can also be used)
16MB of fast Micron PSDRAM and 4MB
of Intel StrataFlash Flash ROM
Xilinx Platform Flash ROM that stores
FPGA configurations indefinitely
High efficiency switching power supplies
(good for battery powered applications)
50MHz oscillator
Connector for 1/8 VGA hi-res graphics
LCD panel or 16x2 character LCD display
60 FPGA I/O’s routed to expansion
connectors (one high-speed Hirose FX2 connector and four 6-pin headers)
8 LEDs, 4-digit seven-segment display, 4 pushbuttons, 8 slide switches
Ships in a convenient plastic carry case (together with USB cable)
