ARIES Embedded has announced that it will present their new System-on-Module (SoM) M100PFS at Embedded World 2020, stand 441 in hall 3A from February 25th to 27th, 2020. The M100PFS SoM is based on the PolarFire SoC, the System-on-Chip (SoC) FPGA family from Microchip that combines a high-performance 64-bit RISC-V multicore processor subsystem with low-power FPGA technology.

“Our new platform enables customers to easily take advantage of the PolarFire SoC’s hardened real-time, Linux capable, RISC-V processor subsystem integrated with the PolarFire family, the industry’s lowest-power, mid-range FPGAs,” stated Andreas Widder, Managing Director of ARIES Embedded. “Applications can benefit from the low power consumption, thermal efficiency, and defence-grade security for a range of embedded systems that require deterministic operation.”

The new M100PFS FPGA SoM is well suited for secure, power-efficient computation in a wide range of applications including Smart Embedded Vision, Industrial Automation, Communications, and Industrial Internet of Things.

The 74 by 42mm small M100PFS SoM runs with low device static power, low inrush current and low-power transceivers. The PolarFire FPGA technology stands out for its reliability with single-event upset (SEU) immunity, built-in SECDED and LSRAM memory interleaving built into the FPGA fabric. In addition, SECDED runs on all processor memory resources and the system controller suspend mode serves safety-critical designs.

Several features support security aspects: for example, Cryptography Research Incorporated (CRI)-patented differential power analysis (DPA) bit stream protection, integrated dual physically unclonable function (PUF), and 56 KB of secure, non-volatile memory (sNVM).

The PolarFire SoC onboard the M100PFS SoM from ARIES Embedded combines a Quad 64-bit RISC-V 64GC core and a 64-bit RISC-V 64 IMAC monitor core. The SoM uses the FCVG484 package that scales from the PolarFire SoC’s 23k logic element (LE) device up to the 250k LE device. A SoM offering the largest 460k LE PolarFire SoC device will be offered in later versions.

The RISC-V CPU micro-architecture implementation is a simple 5-stage, single issue, in-order pipeline that is immune to the Meltdown and Spectre exploits found in common out-of-order machines.

All five CPU cores are coherent, with the memory subsystem allowing a versatile mix of deterministic real-time systems and Linux in a single multi-core CPU cluster. Processor I/Os include: two Gigabit Ethernet, USB 2.0 OTG, two CAN 2.0 A and B, Execute in place Quad SPI flash controller, five multi-mode UARTs, two SPI, 2 I2C, RTC, GPIO, and five watchdog timers.

Memory comprises 1/2/4 GByte LPDDR4 RAM dedicated to the HMS, 1/2/4 GByte LPDDR4 RAM dedicated to the FPGA, 32 Mbit NOR Flash, and four to 64 GByte eMMC memory. The default configuration contains Gigabit Ethernet, UART, CAN, SPI, I²C, and USB.

ARIES Embedded will introduce a first prototype of the M100PFS SoM at Embedded World trade show at stand 441 in hall 3A from February 25th to 27th, 2020 in Nuremberg, Germany, and will start shipping boards to customers in the fourth quarter of 2020.
