In addition to the Flash memory features listed in the previous table, the MSPM0 Flash memory also has the following features:

  • In-circuit program and erase supported across the entire supply voltage range
  • Internal programming voltage generation
  • Support for EEPROM emulation with up to 100 000 program/erase cycles on the lower 32KB of the Flash memory, with up to 10 000 program/erase cycles on the remaining Flash memory (devices with 32KB support 100 000 cycles on the entire Flash memory)
