PolarBerry is a System on Module (SoM) SBC utilizing the Microsemi PolarFire SoC, which integrates a low-power FPGA with a highly-secure, four-application-core, 64-bit RISC-V subsystem that is Linux-capable.

Application Flexibility

PolarBerry is designed to be application-flexible, while also being quick to use and deploy. Its combination of features make it perfect for applications that require high-performance but a low power draw, defense-level security, a real-time, deterministic RISC-V processor that’s capable of Linux, a small physical profile, immediate connectivity, or custom extensibility - such as those in the autonomous vehicle or defense industries.

FPGA, RISC-V, and Linux

PolarBerry with its PolarFire SoC provides a system with hardcore, deterministic, coherent RISC-V processing and programmable logic - enabling real-time systems and Linux with unparalleled security features.

SBC and SoM Form-factor

As the board is essentially an SBC in a SoM form-factor, it can be utilized as a standalone module or along with a carrier board like the Sundance DSP SE215 carrier or one of your own design.

A Raspberry Pi connector, two CAN bus interfaces, and an RJ45 port for Ethernet allows PolarBerry to tap into extensive ecosystems, and its Samtec connectors provide high-speed communication to a carrier board for powerful peripheral customization.

For example, PolarBerry works well with our SE215 PCIe SoM carrier board which provides access to an FMC and additional interfaces like an SFP+ module.

PolarBerry utilizes the PolarFire FPGA fabic and RISC-V processors to provide high levels of security for real-time applications. It features advanced code and bitstream security and anti-tamper engines. These measures give PolarBerry previously unheard-of, defense-level security for an SBC/SoM.
