Actel Corporation has completed the stringent MIL-STD 883 Class B qualification of its four-million gate radiation-tolerant RTAX-S field-programmable gate array (FPGA). The high-density RTAX4000S device has completed 1,000 hours of high-temperature operating life (HTOL) testing and nearly 80,000 total hours of life testing data to date. The device specific testing data is in addition to the more than 2,000,000 device hours of testing and rapidly accumulating flight heritage achieved by the remainder of the RTAX-S family. The qualification of the device, combined with its usable error-corrected on-board memory and large number of user I/O, make it ideal 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. Competing high-density FPGA solutions require user-instantiated triple module redundancy (TMR), which can consume more than two-thirds of the device’s available logic. The RTAX4000S offers the inherent flexibility of the programmable fabric, delivering cost and time-to-market advantages over radiation-hardened (RH)-ASICs with their long lead times and high up-front tooling charges that, in combination with minimal volume requirements for many space applications, often translate to higher total solution costs.
