External flash/ram: necessary?

Hey all. Working on a board with a 20100E, and with the chip shortage, I had a simple question: if I’m not doing any graphics processing, is adding external flash and ram necessary? What workloads would the on-chip amounts be too low for?

Adding external ram to the SC20100 is impossible since it doesn’t have the required pins.

Adding external flash can be useful for:

  • Big softwares
  • Storing data
  • Running tiny file system to store files
  • In field update

Make sure to add the correct flash chip. I once added the wrong one and it didn’t get recognized by TinyCLR. :slight_smile:
