8.2.4 EEPROM
The TM4C129XNCZAD microcontroller includes an EEPROM with the following features:
■ 6Kbytes of memory accessible as 1536 32-bit words
■ 96 blocks of 16 words (64 bytes) each
■ Built-in wear leveling
■ Access protection per block
■ Lock protection option for the whole peripheral as well as per block using 32-bit to 96-bit unlock
codes (application selectable)
■ Interrupt support for write completion to avoid polling
■ Endurance of 500K writes (when writing at fixed offset in every alternate page in circular fashion)
to 15M operations (when cycling through two pages ) per each 2-page block.
8.2.4.1 Functional Description
The EEPROM module provides a well-defined register interface to support accesses to the EEPROM
with both a random access style of read and write as well as a rolling or sequential access scheme.
A protection mechanism allows locking EEPROM blocks to prevent writes under a set of
circumstances as well as reads under the same or different circumstances. The password model
allows the application to lock one or more EEPROM blocks to control access on 16-word boundaries.
