Not on Digikey or Mouser, they haven't. Yes, there have been an assortment of dodgy "RISC-V" chips from dodgy Chinese suppliers that would appear and disappear like spectral invaders from another dimension. Until last year, though, I couldn't plan around being able to buy and put a RISC-V chip in a product. Now I can.
