Software to manipulate EEPROM/FLASH memory

hc12mem is a command line tool for embedded microcontroller developers using Freescale’s HCS12-family MCUs. It can

  • erase/read/write/protect internal EEPROM memory
  • erase/read/write internal FLASH memory
  • protect/unprotect whole MCU

Supported MCUs almost every HCS12 derivative

A32, A64, A128, A256, A512, C32, C64, C96, C128, GC16, GC32, GC64, GC96, GC128, D32, D64, D128, D256, D512, E32, E64, E128, E256, H128, H256, UF32, NE64.
