HiFive Unmatched

Based on the success of the HiFive Unleashed and Linux software ecosystem enablement, the HiFive Unmatched ushers in a new era of RISC-V Linux development with a high performance development platform in a standard PC form factor. The development board is powered by the SiFive Freedom U740 (FU740), an SoC that includes a high-performance multi-core, 64-bit dual-issue, superscalar RISC-V processor (SiFive Essential™ U74-MC) with 16GB of DDR4, Gigabit Ethernet, PCIe expansion, USB 3, and M.2 sockets for Wi-Fi, Bluetooth and NVMe storage. A 5th core (a SiFIve Essential S71 monitor core) is available for real time applications. SiFive Mix+Match technology offers a potent combination of application and real-time processing. The S71 (RV64IMAC) can service auxiliary functions and cooperate with the U74-MC cluster, making this an ideal heterogeneous software development platform where Linux and a RTOS can co-exist.

NOTE: Due to incredible customer demand, we quickly sold out of our production run of HiFive Unmatched boards; with COVID-related supply chain issues, we have decided to focus on the upcoming, more powerful development system based on the Horse Creek SoC and platform co-developed with Intel rather than trying to restart HiFive Unmatched production.
