Description of product

Crowd Supply HiFive1 Arduino-Compatible RISC-V Development Kit

Crowd Supply HiFive1 Arduino-Compatible RISC-V Development Kit features the Freedom E310, a commercially available RISC-V SoC 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, and a debug module. Other features inclide 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.
