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.

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.

Today's applications are expected to meet demanding functional requirements, and must do so securely by protecting both application design and information. Protecting design and information calls for secure hardware, and design and data security. Microchip PolarFire FPGAs and PolarFire SoC FPGAs provide a solid foundation for all application security needs.

Design security protects the design intellectual property (IP) and other sensitive information such as cryptographic keys that are used for the FPGA configuration. Design IP includes designer's logic design, firmware code, and security settings loaded in the device. Design security assures that the user design programmed onto a device is secure, and operates as intended, for the life of the product. Data security protects application data—stored, communicated, or computed at run-time—from being copied, altered, or corrupted. PolarFire FPGA and PolarFire SoC FPGA devices have a dedicated crypto processor, referred as User Cryptoprocessor, for data security applications.

The following table summarizes the important attributes for a strong security.

The rest of the chapters describe how these attributes are implemented in both the device families. These devices include features that provide enhanced security during all stages of the device life cycle from silicon manufacturing, user key injection and bitstream programming, to field updates, and finally to device decommissioning.
