SoM1-SoC

SoM1-SOC is an innovative system-on-module that uses the Microchip PolarFire SoC FPGA, which combines a low-power FPGA with a 64-bit, Linux-capable RISC-V processor. This module offers a high level of security, performance, and efficiency for embedded systems development. SoM1-SOC is populated with an MPFS460T-1FCVG1152E device which has 461K logic cells, 20 high-speed transceivers, two PCIe hard blocks, 136 MSS IOs, 180 HSIO, and 288 GPIOs. The MSS IOs are connected to DDR4, eMMC, and ETH PHY Devices. The HSIO and GPIO pins are routed to connectors, DDR4, and SPI flash. The MPFS460T PolarFire SoC provides abundant resources to meet the needs of complex embedded systems:

  • 4GB 32-bit wide DDR4-3200 providing memory to the MSS (MT40A1G16TB-062EIT DDR4)
  • 8GB 64-bit wide DDR4-3200 for additional FPGA memory (MT40A1G16TB-062EIT DDR4)
  • 16GB eMMC 5.1 flash storage
  • 10/100/1000 Ethernet PHY with RGMII interface

When populated with the MPFS250T-FCVG1152E device, it will have 254K logic cells, 16 high-speed transceivers, two PCIe hard blocks, 136 MSS IOs, 144 HSIOs, and 228 GPIOs. The MSS I/Os remain the same between the two devices.

The device package is FCVG1152 with speed grade -1.

The SoM1-SOC is one of the most feature-rich SOCs ever to be available on the market. It can be used stand-alone by simply plugging a USB-C cable into the device which acts as both a power supply, UART, JTAG, and highspeed data transfers to a host system. Additionally, a Harting iX industrial ethernet connector providing 1Gbps networking is installed on the module along with 2 RGB LEDs for user applications.

When installed on an SE301, the feature set is expanded even further allowing the device to access a FMC HPC connector, 4 lanes of PCIe, highspeed networking via SFP+, a Display port for terminal output, SATA for data storage, and a robust inter-module connection featuring 4 transceivers and a multitude of GPIO.
