High Endurance Flash (HEF)

The High-Endurance Flash is a block of 128 memory locations, found at the top of the Flash program memory that is ensured to provide a superior endurance, equal to that of a traditional data EEPROM.


High Endurance Flash (HEF)

  • 128 B of non-volatile data memory
  • Shared with flash program memory
  • 100 K E/W cycle high endurance flash

Example Uses

  • Data logging
  • Look-up tables
  • Configuration and calibration settings


  • Provides non-volatile data storage
  • Low cost alternative to EEPROM
  • Robust data storage and durability
