The Opal Kelly XEM3050 is an FPGA development board based on a 4,000,000-gate Xilinx Spartan-3 FPGA. In addition to a high gate-count FPGA, the XEM3050 utilizes the high transfer rate of USB 2.0for configuration downloads, enabling an almost instant reprogramming of the FPGA.

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.

Two completely independent 32-MByte SDRAMs are great for high-performance applications where separate memory busses are required.



A high-performance 9 MiB (512k x 18) synchronous SRAM enables volatile storage that can persist between FPGA configurations.



An 8-Mbit SPI Serial Flash device is included for non-volatile storage. A separate Xilinx Platform Flash is available for FPGA configuration data.



The XEM3050 is powered by two high-efficiency switching power supplies to reduce your design burden and guarantee clean, stable power to the FPGA.
