Hello everyone, I am a ruffian balance, is a serious technical ruffian. Today ruffian balance to introduce to you is the domestic RISC-V core MCU manufacturers (2020).

Although the TREND of RISC-V has been blowing for several years, 2019 is the first year for it to truly enter the mainstream market. Recently, a large number of domestic chip companies have risen, and many of them want to have a role in risC-V new track. After all, THE ARM kernel has long been a red sea, while RISC-V is still in the blue sea. Risc-v MCU products (not necessarily mass production)

  • Note 1: This article mainly includes vendors that release RISC-V MCUS in 2020.
  • Note 2: This article will continue to be updated, please let me know if you missed any vendors in the comments.
