Microchip announces the RT PolarFire FPGA that is optimised to meet the most demanding requirements in spacecraft payload systems’ high-speed data paths with the lowest possible power consumption and heat generation.
Developers of spacecraft electronics use Radiation Tolerant (RT) Field Programmable Gate Arrays (FPGAs) to create on-board systems that meet the demanding performance needs of future space missions, survive the brutal launch process, and continue to operate reliably in the harsh environment of space. Microchip has extende its RT FPGA offering to bring these capabilities to emerging high-performance space applications.
A growing number of space applications need greater computational performance so they can transmit processed information rather than raw data and make optimal use of limited downlink bandwidth. The RT PolarFire FPGA enables this at significantly lower cost and with faster design cycles than possible with Application-Specific Integrated Circuits (ASICs). It also significantly reduces power as compared to the alternative of using FPGAs based on Static Random Access Memory (SRAM) while eliminating their vulnerability to radiation-induced configuration upsets. The RT PolarFire FPGA is supported by all necessary radiation data, specifications, package details and tools customers need to start new designs now, initially with the commercial version of the device.
The RT PolarFire FPGA builds on the success of Microchip’s RTG4 FPGA, which has been widely deployed in space applications that require its radiation-hardening by design against Single Event Upsets (SEUs) and inherent immunity to Single Event Latch-ups (SELs) and configuration upsets. For space applications that require up to five times the computing throughput, the RT PolarFire FPGA provides 50 percent more performance and triple the logic elements and Serialiser-Deserialiser (SERDES) bandwidth.
It also provides six times the amount of embedded SRAM to enable more system complexity than previously possible using FPGAs and withstands Total Ionising Dose (TID) exposure beyond the 100 kilorads (kRads) that is typical of most earth-orbiting satellites and many deep-space missions.
