Actel RTAX FPGA Family Enhancements

Actel has made enhancements to their radiation-tolerant RTAX-S and RTAX-SL space-flight FPGAs. The RTAX-S/SL FPGA family is ideal for space-flight applications requiring built-in protection from radiation-induced single-event upset (SEU) events. RTAX-S/SL offers high performance at densities of up to 4 million equivalent system gates and 840 user I/Os for space-based applications. The RTAX-S/SL family features SEU-hardened flip-flops implemented without any user intervention, and offers the benefits of user-implemented triple module redundancy (TMR) without the associated overhead.

RTAX-S/SL FPGA Family Enhancements

  • Reduced static power consumption for RTAX-SL FPGAs of up to 80% compared to RTAX-S FPGAs — this saving in static power is particularly important for systems that go into stand-by mode and need to retain register and memory states while the spacecraft is running in battery mode (for example, while passing through the earth’s shadow)
  • A faster speed grade for the 4-million gate RTAX4000S FPGA, bringing 10% higher performance to the largest SEU-protected radiation-tolerant FPGA

  • A new, low-power RTAX4000SL FPGA, available in CQFP352 and CGA/LGA 1272 packages, reducing static power consumption by 50% compared to the RTAX4000S FPGA

  • New 624-pin CCGA and LGA packages for the RTAX250S/SL FPGA, giving designers a 17% increase in available I/Os and more than 50% savings in footprint. Devices are available today that are screened to MI- STD-883 Class B, Actel Extended flow, and Actel EV flow (which has processing steps identical to QML Class V) specifications

  • Increased absolute maximum junction temperature for the RTAX-S/SL FPGA to 135 degrees C, giving designers an additional 10 degrees C buffer to run the devices faster or at higher case temperatures
