Details
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.
The updated HiFive Unmatched Rev B boards are available through Mouser and are ready for fulfillment from the warehouse a couple of weeks from the time an order is placed.
