Very-low-power FPGAs have been around for a while, but often there’s the need for those that can handle high-speed serial interfaces like PCI Express or incorporate hard-core processors. Microchip’s latest PolarFire release actually fills out the lower end with a 50K logic elements (LE) and an SoC version with 25K LE that has the same five-core, RISC-V processor complex as the higher-end PolarFire SoC family (Fig. 1).
