  • Parallel Flash chips have too many pins to control with just a single Arduino Uno. You will need to add some additional ICs to expand the IO. Fortunately the protocol for writing to them is simple, you will just have to write some code to actually transfer the file from your PC to the Arduino as it's writing (the Flash is too big to just store in the arduino). https://github.com/beneater/eeprom-programmer has an example circuit/code.

  • If you can dig up a pair of shift registers, you can build this with an Arduino: https://tomnisbet.github.io/TommyPROM/ I’ve used it for 29 series flash parts before, although not the specific one you have.
