Introduction
(Ask a Question)This user guide describes the fabric architecture and its components available in the PolarFire® family. The FPGA fabric is common to the PolarFire family, which consists of the following FPGA devices.
- PolarFire FPGAs
- Microchip's PolarFire FPGAs are the fifth-generation family of non-volatile FPGA devices, built on state-of-the-art 28 nm non-volatile process technology. PolarFire FPGAs deliver the lowest power at mid-range densities. PolarFire FPGAs lower the cost of mid-range FPGAs by integrating the industry’s lowest power FPGA fabric, lowest power 12.7 Gbps transceiver lane, built-in low power dual PCI Express Gen2 (EP/RP), and, on select data security (S) devices, an integrated low-power crypto co-processor.
- PolarFire SoC FPGAs
- Microchip's PolarFire SoC FPGAs are the fifth-generation family of non-volatile SoC FPGA devices, built on state-of-the-art 28 nm non-volatile process technology. The PolarFire SoC family offers industry's first RISC-V® based SoC FPGAs capable of running Linux®. It combines a powerful 64-bit 5x core RISC-V Microprocessor Subsystem (MSS), based on SiFive’s U54-MC family, with the PolarFire FPGA fabric in a single device.
- RT PolarFire FPGAs
- Microchip's RT PolarFire FPGAs combine our 60 years of space flight heritage with the industry’s lowest-power PolarFire FPGA family to enable new capabilities for space and mission-critical applications. RT PolarFire FPGA family includes RTPF500T, RTPF500TL, RTPF500TS, RTPF500TLS, RTPF500ZT, RTPF500ZTL, RTPF500ZTS, and RTPF500ZTLS devices.
- RT PolarFire SoC FPGAs
- Microchip's RT PolarFire SoC FPGAs are designed to enable high-performance data processing. Our radiation-tolerant PolarFire SoC FPGA is the industry’s first embedded, real-time, Linux®-capable, RISC-V®-based Microprocessor Subsystem (MSS) on the flight-proven RT PolarFire FPGA fabric. With our extensive Mi-V ecosystem, designers can develop lower-power solutions for the challenging thermal environments seen in space. RT PolarFire SoC FPGA family includes RTPFS160ZT, RTPFS160ZTL, RTPFS160ZTS, RTPFS160ZTLS, RTPFS460ZT, RTPFS460ZTL, RTPFS460ZTS, and RTPFS460ZTLS devices.
