The Opal Kelly XEM3001 is an FPGA development board based on a 400,000-gate AMD Spartan-3 FPGA (XC3S400-4PQ208C). In addition to a high gate-count FPGA, the XEM3001 utilizes the high transfer rate of USB 2.0 for configuration downloads, enabling an almost instant reprogramming of the FPGA. The XEM3001 features flexible clocking with a multi-output clock generator that can generate clock frequencies from 1 MHz to 150 MHz. If higher frequencies are needed, the clock multipliers in the FPGA can be used.

FrontPanel™ SDK

Opal Kelly’s FrontPanel SDK is an easy-to-use, robust API for communication, configuration, and interfacing to your PC, Mac or Linux hardware. FrontPanel handles all the interaction between your software and the FPGA internals, dramatically reducing the time and effort required to interface to a design.

FlashPrototyping and OEM Integration

Opal Kelly FPGA integration modules are designed to be the ideal turnkey solution for prototypes and OEM product integration. With the complete FrontPanel SDK, there’s simply no faster, more reliable, production-ready way to jump start your FPGA design.

Virtual interface elements such as buttons, LEDs, and hex displays make cumbersome "I/O Boards" a thing of the past.



86 I/Os and 6 CLK pins are all arranged on a common 0.1" grid for easy prototyping.



The on-board PLL provides flexible clocking to the FPGA and expansion connectors.



The XEM3001 comes configured as a bus-powered device. With the removal of a jumper, you can configure the module to be self-powered.
