Overview

The Nexys2 circuit board is a complete,

ready-to-use circuit development platform

based on a Xilinx Spartan 3E FPGA. Its on-

board high-speed USB2 port, 16Mbytes of

RAM and ROM, and several I/O devices and

ports make it an ideal platform for digital

systems of all kinds, including embedded

processor systems based on Xilinx’s

MicroBlaze. The USB2 port provides board

power and a programming interface, so the

Nexys2 board can be used with a notebook

computer to create a truly portable design

station.

The Nexys2 brings leading technologies to a

platform that anyone can use to gain digital

design experience. It can host countless

FPGA-based digital systems, and designs

can easily grow beyond the board using any

or all of the five expansion connectors. Four

12-pin Peripheral Module (Pmod) connectors

can accommodate up to eight low-cost

Pmods to add features like motor control, A/D

and D/A conversion, audio circuits, and a host

of sensor and actuator interfaces. All user-

accessible signals on the Nexys2 board are

ESD and short-circuit protected, ensuring a

long operating life in any environment.

The Nexys2 board is fully compatible with all

versions of the Xilinx ISE tools, including the

free WebPack. Now anyone can build real

digital systems for less than the price of a

textbook.

Power Supplies

The Nexys2 board input power input bus can be driven from a USB cable, from a 5VDC-15VDC,

center positive, 2.1mm wall-plug supply, or from a battery pack. A shorting block loaded on the

“power select” jumper selects the power source. The USB circuitry is always powered from the USB

cable – if no USB cable is attached, the USB circuitry is left unpowered.

• 500K-gate Xilinx Spartan 3E FPGA

• USB2-based 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 Micron PSDRAM &16MB of Intel StrataFlash ROM

• Xilinx Platform Flash for nonvolatile FPGA configurations

• Efficient switch-mode power supplies (good for battery

powered applications)

• 50MHz oscillator plus socket for second oscillator

• 60 FPGA I/O’s routed to expansion connectors (one high-

speed Hirose FX2 connector and four 6-pin headers)

• 8 LEDs, 4-digit 7-seg display, 4 buttons, 8 slide switches

• Ships in a plastic carry case with USB cable
