SoM sports hardened 64-bit, multicore RISC-V MPU subsystem

Sundance has launched PolarBerry, the first production and deployment-ready SoM with a hardened 64 bit, multicore real-time, Linux-capable RISC-V MPU subsystem to deliver an unparalleled combination of defense-grade security, low power consumption, and thermal efficiency for embedded systems development.

With Microchip Technology Inc.’s PolarFire SoC field-programmable gate array (FPGA) at its heart, providing a deterministic, coherent 64-bit RISC-V CPU cluster and a deterministic L2 memory subsystem enabling the implementation of secure Linux and real-time applications, PolarBerry is ideally suited to the development of embedded computing and real-time applications based on RISC-V processors as an alternative to ARM. Typical applications will be found in the defense/mil-aero, AI/ML, communications, automotive, industrial automation, and imaging markets as well as the Internet of Things.

PolarBerry’s compute engine delivers up to 50% lower power than alternative FPGAs, 250k logic elements (LEs), and features four high-speed, low-power transceivers from 250Mbps to 12.7Gbps. The PolarFire SoC FPGA’s power consumption is 12W maximum and power provided directly from the PolarBerry SoM to enable embedded solutions.

The PolarBerry SoM offers all the important attributes for strong SoC/FPGA design security including anti-cloning protection, device-level anti-tamper features, bitstream protection, key management, FPGA hardware access control, secure boot and physical memory protection (PMP) as well as supply chain assurance. It also features a 40 pin Raspberry Pi (RPI) interface to allow standalone operation and rapid application development by providing up to 26 GPIOs, 20 of which can be assigned to SPI, UART, CAN, or other interfaces. All RPI signals are 3.3V logic. Associated onboard PolarBerry SoM peripherals include 4GB of 32-bit wide DDR4 memory, 128MB SPI Serial NOR FLASH for storing the boot image, and programmable clocks to provide flexible clocking to the FPGA and high-speed transceivers. There is also an RJ45 Ethernet socket with a 100/1000Base-T interface, two CAN 2.0 physical layers, a JTAG interface for programming, and 4GB of eMMC non-volatile storage. Samtec connectors provide high-speed communication to a carrier board for powerful peripheral customization. The power consumption of the module is 16W with the power it can be applied via a PRI interface or carrier board.

The PolarBerry SoM measures just 55mm by 85mm and has an operational temperature range of 0°C and +70°C. It can also be installed on Sundance’s PCIe SoM carrier to provide access to an FMC and additional interfaces.

PolarBerry is part of Microchip Technology’s “Get Launched!” campaign and has been released now for early adaptors at a price of US$995 for delivery in January 2021. For more information about Microchip Technology’s “Get Launched!” campaign, visit https://www.crowdsupply.com/microchip/get-launched.
