I'm New to RISC-V


(Peter) #1

Hi guys, I’m new here. I’ve been programming microcontrollers in assembler of various types over the years and now want to start programming RISC-V microcontrollers.
Can someone let me know what is the fastest RISC-V micro controller in LQFP package available today.
I’ve only found the GIGADEVICE GD32V103VBU6 microcontroller which runs at 108Mhz, 128k Flash memory, 32k Sram in a 100pin LQFP package.
Thats great but I’m looking for something RISC-V, at least 300Mhz, 2MB FLASH Memory, SRAM, 16bit or 32bit I/O Ports and any peripherals that come with it. Eg. SPI, RTC, etc. I know this may not be available but there’s no harm in asking.
Anyway please let me know if you guys know of any.
Thanks guys,
Pete :slight_smile:

You can find a list of ASICs at
https://riscv.org/risc-v-cores/
Turn off cores and soc platforms to see just the socs (aka ASICs). I don’t know the stats for the non-SiFive parts. For the SiFive parts, we are currently only producing the HiFive1 RevB
https://www.crowdsupply.com/sifive/hifive1-rev-b
the page says it can run as fast as 320MHz.

Hi Jim, thank you for the info. The PIC32MZ have the RISC CPU running at 252Mhz with 2MB Flash memory but the one you mentioned at 320Mhz is more appealing.
Thanks Jim
