RISC-V delivers a new level of extensible software and hardware freedom on architecture, paving a new way for computing design and innovation.

The HiFive1 is an Arduino-compatible development kit featuring the Freedom E310, the industry’s first commercially available RISC-V SoC.
Freedom Everywhere

The Freedom E310 (FE310) is the first member of the Freedom Everywhere family of customizable SoCs. Designed for microcontroller, embedded, IoT, and wearable applications, the FE310 features SiFive’s E31 CPU Coreplex, a high-performance, 32-bit RV32IMAC core. Running at 320+ MHz, the FE310 is among the fastest microcontrollers in the market.

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.

HiFive1
A RISC-V-based, Open-Source, Arduino-Compatible Development Kit

The HiFive1 is an Arduino-Compatible development kit featuring the Freedom E310, the industry’s first commercially available RISC-V SoC.

RISC-V (pronounced "risk-five") is a new instruction set architecture (ISA) that was originally designed to support computer architecture research and education and is now set to become a standard open architecture for industry implementations under the governance of the RISC-V Foundation. The RISC-V ISA was originally developed in the Computer Science Division of the EECS Department at the University of California, Berkeley.
