Continuing to support the evolving needs of space system developers, Microchip Technology (NASDAQ:MCHP) has announced two new milestones for its Radiation-Tolerant (RT) PolarFire® technology: MIL-STD-883 Class B and QML Class Q qualification of the RT PolarFire RTPF500ZT FPGA and availability of engineering samples for the RT PolarFire System-on-Chip (SoC) FPGA. These achievements underscore the company's more than 60 years of spaceflight heritage and its commitment to delivering highly reliable, low-power solutions for the most demanding space applications.

MIL-STD-883 Class B and Qualified Manufacturers List (QML) Class Q are industry standards that define rigorous testing and qualification processes for microelectronic components used in high-reliability applications, such as space and defense. MIL-STD-883, developed by the U.S. Department of Defense, outlines methods for environmental, mechanical and electrical testing to ensure device reliability under extreme conditions. QML Class Q, managed by the Defense Logistics Agency (DLA), certifies that manufacturers consistently produce components meeting these stringent requirements. 

Unlike traditional SRAM-based FPGAs, RT PolarFire devices utilize nonvolatile technology, making them immune to configuration memory upsets caused by radiation. This eliminates the need for external mitigation measures, helping reduce system complexity and overall cost. RT PolarFire FPGAs consume up to 50% less power than mid-range SRAM-based alternatives, enabling satellite designers to optimize Size, Weight and Power (SWaP) without compromising mission-critical reliability. The PolarFire RTPF500ZT FPGA advances the family's capabilities, offering enhanced Single Event Latch-up (SEL) radiation performance and increased robustness for inflight programming compared to the original RTPF500T.
