Rad-hard PolarFire FPGAs is available in engineering silicon
Engineering silicon of the RT PolarFire FPGA is being shipped by Microchip, while the device is being qualified to spaceflight component reliability standards.
Designers can now create hardware prototypes with all the same electrical and mechanical performance that the space-qualified RT PolarFire FPGAs will provide for high bandwidth, on-orbit processing systems with industry low power consumption and the ability to withstand radiation effects in space, adds Microhip.
The RT PolarFire FPGAs increase computational performance so satellite payloads can transmit processed information rather than raw data. They are also designed to optimise use of limited downlink bandwidth. The devices exceed the performance, logic density and SerDes bandwidth of any other currently available space-qualified FPGA, the company claims.
They also enable more system complexity than previous FPGAs and withstand Total Ionizing Dose (TID) exposure beyond the 100 kilorads (kRads) typical of most earth-orbiting satellites and many deep-space missions. Their power-efficient architecture reduces power consumption up to 50 per cent compared to SRAM FPGAs, leveraging SONOS configuration switches that also eliminate the problem of configuration upsets due to radiation in space.
Microchip is qualifying its RT PolarFire RTPF500T FPGAs to Mil Std 883 Class B, QML Class Q and QML Class V – the highest qualification and screening standard for monolithic ICs in space. Designed to survive a rocket launch and meet demanding performance needs in space, RT PolarFire FPGAs can be used in applications including high resolution passive and active imaging, precision remote scientific measurement, multi-spectral and hyper-spectral imaging and object detection and recognition using neural networks. These applications require high levels of operating performance and density, low heat dissipation, low power consumption and low system level costs, advises Microchip.
Describing the possibilities for high-rel development, Bruce Weyer, vice president of Microchip’s FPGA business unit, said: “This is a major milestone as we release RT PolarFire FPGA engineering silicon to our customers and begin the spaceflight qualification process through full QML Class V standards.
“Many of our customers have already jump-started satellite system payload development using our commercial PolarFire MPF500T FPGAs and now all prototyping can be done with silicon that will be identical in form, fit and function to our eventual flight-qualified RT PolarFire FPGAs,” he added.
The RT PolarFire RTPF500T FPGA engineering models are available in a hermetically sealed ceramic package with land grid, solder ball and solder column termination options. They are supported by development boards, Libero software tool suite and radiation data.
