M100PFS-250BAAB

Overview

The M100PFS-250BAAB is a System on Module (SoM) based on the Microsemi PolarFire SoC FPGA, specifically utilizing the MPFS250T device. This component integrates 254K logic elements and features a hardened RISC-V MPU subsystem comprising four 64-bit RV64GC application cores and one 64-bit RV64IMAC monitor core, all operating at a maximum frequency of 667 MHz. The module includes dedicated memory resources: 2 GB DDR4 RAM for the Hardened Memory Subsystem (HMS) and 512 MB DDR4 RAM for the FPGA fabric. It also incorporates 8 GB eMMC NAND Flash storage and supports various interfaces including dual Gigabit Ethernet, USB 2.0 OTG, and PCIe.

Feature Summary

• Microsemi PolarFire SoC FPGA (MPFS250T) with 254K logic elements and 784 math blocks
• Quad-core 64-bit RISC-V processor cluster running up to 667 MHz
• Dedicated memory architecture with 2 GB HMS DDR4 and 512 MB FPGA DDR4
• Integrated peripherals including 2x Gigabit Ethernet, USB 2.0 OTG, and 2x PCIe

Applications

• Industrial automation systems requiring deterministic real-time performance
• Embedded Linux platforms needing low power consumption and thermal efficiency
• Defense and aerospace applications demanding high security and reliability
• Fast prototyping and evaluation in industrial environments using the M100PFSEVP kit

Procurement Notes

Verify the specific configuration against the datasheet, as the M100PFS series offers variable memory options. The M100PFS-250BAAB model explicitly specifies 2 GB DDR4 for the HMS and 512 MB DDR4 for the FPGA. Confirm that the required storage capacity matches the integrated 8 GB eMMC NAND Flash. Ensure compatibility with the M100PFSEVP baseboard if evaluation or initial development is planned.

Selection Notes

Select this module when a mid-range FPGA solution with integrated RISC-V processing is required. The MPFS250T variant provides 254K logic elements, suitable for complex designs needing 16 SERDES lanes and 2 PCIe interfaces. Consider the non-volatile flash-based technology for SEU immunity and lower power consumption compared to SRAM FPGAs. Verify that the 667 MHz clock speed meets the throughput requirements for the intended Linux and real-time applications.

Part Context

The M100PFS-250BAAB is part of the M100PFS family of System on Modules developed by ARIES Embedded GmbH. These modules are built upon the PolarFire SoC FPGA architecture from Microchip (formerly Microsemi). The family includes variants based on different PolarFire SoC devices, such as the MPFS025T, MPFS095T, MPFS160T, and MPFS250T, allowing designers to scale performance and resource availability based on project needs.

Replacement Considerations

Direct replacement requires matching the PolarFire SoC FPGA package and pinout. Alternative modules from other vendors may require significant hardware redesign due to differences in processor architecture (RISC-V vs. ARM) and FPGA fabric. Evaluate software migration efforts if switching between different RISC-V implementations or FPGA families.
