The radiation-tolerant RTAX-SL FPGA family is a low-power version of existing device families that targets high-reliability space-flight designs. The device provides approximately 50% lower standby current of the standard product at worst-case conditions. Gate densities of the FPGA extend from 250,000 to 4 million equivalent system gates and also have 840 user I/Os.

The family, composed of the RTAX250SL, RTAX1000SL, and RTAX2000SL, offers radiation performance, embedded memory, SEU-hardened flip-flops, high I/O count, multiple I/O standard support, and hermetic packaging. Hot-swap and cold-sparing capabilities enable a device to be turned off for minimal power consumption during long space missions. An EV version provides a quality level for high-reliability systems used in space deployment.
