Microchip Technology Inc. has announced that its radiation-tolerant (RT) PolarFire RTPF500ZT FPGA has achieved MIL-STD-883 Class B and QML Class Q qualification. The company also released engineering samples for the RT PolarFire SoC FPGA.

MIL-STD-883, developed by the U.S. Department of Defense, provides for methods for environmental, mechanical, and electrical testing to ensure device reliability under extreme conditions, while QML Class Q, managed by the Defense Logistics Agency (DLA), certifies that manufacturers consistently produce components meeting the stringent requirements.

The RT PolarFire devices use nonvolatile technology that make them immune to configuration memory upsets caused by radiation, eliminating external mitigation measures, which help to reduce system complexity and cost.

The RT PolarFire SoC FPGA integrates a real-time, Linux-capable, RISC-V-based microprocessor subsystem with a flight-proven FPGA fabric, enabling deterministic real-time performance. This device has a roadmap to QML Class V and Class Y, making it suited for satellite processing, avionics, and payload control.

The RT PolarFire FPGAs consume up to 50% less power than mid-range SRAM-based alternatives, helping satellite designers to optimize for size, weight, and power. The RTPF500ZT FPGA also offers enhanced single event latch-up (SEL) radiation performance and increased robustness for in-flight programming, compared to the original RTPF500T.

RT PolarFire devices are supported by the Libero SoC Design Suite, an IP library, reference designs, and solution stacks tailored for space applications. RT PolarFire SoC FPGAs also integrate with Microchip’s Mi-V ecosystem for RISC-V development. Development kits and hardware platforms are available for prototyping, hardware validation, and system integration.
