Actel Corp. in Mountain View, Calif., has qualified its 4-million-gate radiation-tolerant RTAX-S field-programmable gate array (FPGA) for mission-critical space systems to MIL-STD 883 Class B. The RTAX4000S device has completed 1,000 hours of high-temperature operating life testing and nearly 80,000 total hours of life testing data to date. This is in addition to more than 2 million device hours of testing. The FPGA is for high-bandwidth processing applications in spacecraft payloads. Rigorous testing and qualification of the RTAX4000S toward QML Class Q and QML Class V certification continues. Hardened by design against radiation single-event upsets (SEUs), the nonvolatile RTAX4000S requires no radiation mitigation techniques. The RTAX4000S device is available now.
