Crowd Supply Article: HiFive1 Rev B

SiFive’s E31 CPU core complex, a high-performance, 32-bit RV32IMAC core with a 16 KB L1 instruction cache, a 16 KB data SRAM scratchpad and hardware multiply/divide. Running at 320+ MHz, the FE310 is among the fastest microcontrollers on the market. The HiFive1 dev board has also been upgraded. Powered by the FE310-G002, the new HiFive1 Rev B has wireless connectivity through an onboard Wi-Fi/Bluetooth module. The USB debugger has been upgraded to Segger J-Link, with support for drag & drop code download. In favor of driving GPIO directly from the FE310, the HiFive1 Rev B supports 3.3 V I/O only. The FE310 is the first open source, commercially available RISC-V SoC. SiFive has contributed the FE310 RTL code to the open source community. Now you can see what’s inside the chip and completely understand how the hardware works.   To read more, please visit: https://www.crowdsupply.com/sifive/hifive1-rev-b.]]>
