HiFive1 (Discontinued)

SiFive HiFive1 is an Arduino-compatible development board featuring the SiFive Freedom E310 (FE310) SoC, making it the best way to prototype and develop RISC-V software. Designed for microcontrollers and edge computing, the FE310 instantiates a SiFive Essential™ E3 Series CPU Core Complex, a high performance 32-bit RV32IMAC core. Additional features include a 16KB L1 Instruction Cache, a 16KB Data SRAM scratchpad, hardware multiply/divide, a debug module, flexible clock generation with on-chip oscillators and PLLs, and a wide variety of peripherals including UARTs, QSPI, PWMs, and timers. Multiple power domains and a low-power standby mode ensure a wide variety of applications can benefit from the FE310. Software development is accelerated with the onboard FTDI FT2232 JTAG debugger connecting over USB to SiFive Freedom Studio, an Eclipse-based IDE. Additionally, your JTAG probe of choice can be connected and used with your favorite debugger and IDE. Freedom Studio is packaged with a prebuilt toolchain and example software projects. Alternatively, the SiFive Freedom Tools download package includes a pre-built toolchain, debugger, and additional command line tools that can be plugged into your own bespoke development environment.
