We got some more details about PolarFire RISC-V FPGA SoC late last year, and we were promised a Linux capable 64-bit RISC-V & FPGA development board with PolarFire SoC Icicle kit in Q3 of 2020. We are already in July 2020. So where is the board? Oh, look! It’s right here on Crowd Supply where it is offered for $499, and shipping is expected to start in mid-September.

RISC-V based PolarFire SoC FPGA by Microsemi may be coming up in the third quarter of this year, but Ali Uzel has been sharing a few details about SAVVY-V advanced open-source RISC-V cluster board made by FOSOH-V (Flexible Open SOurce Hardware for RISC-V) community of developers. It’s powered by Microsemi Polarfire RISC-V SoC MPFS250T with four 64-bit RISC-V cores, a smaller RV64IMAC monitor core, and FPGA fabric that allows 10GbE via SFP+ cages, and exposes six USB Type-C ports. The solution is called a cluster board since up to six SAVVY-V boards can be stacked via a PC/104+ connector and interfaced via the USB-C ports. SAVVY-V cluster board preliminary features and specifications: SoC – Microsemi Polarfire RISC-V SoC MPFS250T with a quad-core 64-bit RV64IMAFDC (RV64GC) processor @ up to 667 MHz, a RV64IMAC monitor core, and FPGA fabric with 250K logic elements; 3.0 CoreMarks/MHz, 2.0 DMIPs/MHz; Also compatible with MPFS160T, MPFS095T, andMPFS025T. System Memory Up to 4GB 32-bit 3200Mbps LPDDR4 […]
Microsemi unveiled PolarFire FPGA + RISC-V SoC about one year ago, but at the time, development was done on a $3,000 platform with SiFive U54 powered HiFive Unleashed board combined with an FPGA add-on board from Microsemi. I’ve now been informed that Microchip has announced its Linux-capable PolarFire FPGA+RISC-V SoC would start shipping in Q3 2020 at the RISC-V summit and that a development kit will be sold for a few hundred dollars. PolarFire SoC FPGA PolarFire SoC FPGA key features and specifications: Mid-Range FPGA optimized for Low Power High-speed serial connectivity with built-in multi-gigabit/multi-protocol transceivers from 250 Mbps to 12.7 Gbps Up to 461k logic elements consisting of a 4-input Look-Up Table (LUT) with a fracture-able D-type flip-flop Up to 31.6 Mb of RAM Power optimized transceivers Up to 1420 18 × 18 multiply-accumulate blocks with hardened pre-adders Integrated dual PCIe for up to ×4 Gen 2 Endpoint (EP) and Root Port (RP) designs High-Speed I/O (HSIO) supporting […]
One of the challenges in starting a new IoT project is the question of what connectivity to use. Depending on the nature of a project, there are several wired and wireless connectivity options that can be used to power a project and ensure it’s a success. We have WiFi, Bluetooth, Zigbee, Zwave, LoRa, ZigFox, Thread, NB-IoT, 3G/4G, and others. You can use from anyone, but which one to use is another thing because most development board only support 1 or 2 of those. Well, with the introduction of the Pitaya Go, you don’t have to worry so much about that decision. The Pitaya Go is an IoT development platform with multiprotocol wireless connectivity built-in. The Pitaya Go is based on the Nordic’s high-end multiprotocol SoC nRF52840 and the Microchip’s extremely low power Wi-Fi network controller ATWINC1500B. The nRF52840 SoC is the most advanced member of the nRF52 Series SoC family, and it is fully multiprotocol capable with full protocol concurrency. It has […]
MicroSemi unveiled PolarFire RISC-V FPGA SoC at the end of last year, bringing an alternative to Xilinx Zynq (Arm Cortex-A9 + FPGA) and UltraScale+ (Cortex A53 + FPGA) SoCs. The system-on-chip is expected to be mass produced later in 2019, so development is done on HiFive Unleashed RISC-V board and its FPGA expansion board. In the meantime, MicroSemi PolarFire FPGAs (without RISC-V hard core) are available now, and ARIES Embedded planning to showcase what they claim is the first PolarFire FPGA system-on-module at Embedded World 2019 with their M100PF SoM targeting industrial applications. ARIES Embedded M100PF key features and specifications: A choice of 3 PolarFire FPGAs MPF100T – 109KLE, 336 Math Blocks (18x18MACC) MPF200T – 192KLE, 588 Math Blocks (18x18MACC) MPF300T – 300KLE, 924 Math Blocks (18x18MACC) System Memory – 512 MiB / 1 GiB / 2 GiB DDR3 RAM Storage – 256 MiB configuration device, 4 GiB eMMC flash by default (Option up to 64GB) 2x Samtec QSH-090-01-F-D-A 180-pin […]
In the past we’ve covered SoCs comprised of Arm cores and FPGA fabric via Xilinx Zynq-7000 series SoCs and Zynq UltraScale+ series MPSoCs, respectively featuring up to two Arm Cortex A9 cores, and up to four Cortex A53 cores. MicroSemi has now announced an alternative, not based on Arm cores, but instead based on SiFive U54-MC RISC-V cores combined with PolarFire FPGA fabric. PolarFire FPGA RISC-V SoC key features & specifications: FPGA – Microsemi PolarFire FPGA Processor Cores – Up to 4x SiFive U54-MC RISC-V cores clocked at up to 1.5GHz (performance similar to Cortex-A35 cores); 28nm process Deterministic Coherent Multi-core CPU Cluster Deterministic L2 Memory Subsystem System Memory I/F – Integrated DDR4/LPDDR4 Controller and PHY Storage – Secure Boot, 128K Boot Flash Debug capability Rich I/Os Low Power – Low static power; power optimized transceivers, up to 50% lower power compared to SRAM based FPGAs So we don’t have the full picture just yet, and we’ll have to wait […]
Earlier this year, Particle unveiled three IoT development boards based on nRF52840 Bluetooth 5/802.15.4 WiSoC and supporting Particle Mesh, which interestingly is not based on Bluetooth Mesh or even Bluetooth, and instead relies on Thread specification/OpenThread implementation, and the 802.15.4 radio of the chip with Bluetooth only used for the initial setup stage. Particle announced the shipping date (October 2018 or… this month) for their Mesh boards pre-ordered in February, as well as three new products in a recent blog post. One of the products is a family of system-on-modules compatible with Particle Mesh, while the other two are related IoT developer tools. Particle Mesh SOMs The Particle Mesh SOMs will have similar names and features as corresponding Particle mesh developers kits such as Boron (NB-IoT / eMTC + BLE + Mesh) and Argon (ESP32 WiFi, BLE + Mesh), but with an edge connector and designed as enterprise-grade, production-scale version of the dev boards. The modules are still in development, […]
