PolarFire™ FPGAs are the fifth-generation family of non-volatile FPGA devices from Microsemi, built on state-of-the-art 28nm non-volatile process technology. Cost-optimized 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 FPGAs can operate at 1.0 V and 1.05 V, offering the end user the ability to trade off power and performance to match the application requirements.

Microsemi's lowest power, cost-optimized mid-range PolarFire FPGA engineering samples are now available for all customers. The PolarFire FPGA family spans from 100K logic elements (LEs) to 500K LEs, features 12.7G transceivers, and offers up to 50% lower power than competing mid-range FPGAs. The devices are ideal for a wide range of applications within wireline access networks and cellular infrastructure, defense and commercial aviation markets, as well as industrial automation and IoT markets.
