This question is about the 2KB of EEPROM in a TM4C123xxx part. According to the datasheet, a 'word' is defined to be 4 bytes. 16 'words' make up a 'block'. 2 'blocks' make up a 'meta-block'.
This sentence from section 1.3.2.4 on EEPROM is confusing me. "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."
1) I think before I can understand what the above sentence means, I need to understand what a page is and what a "2-page block is".
2) For the 500K figure, it says "alternate page in circular fashion". So assuming a fixed offset of say 3, would you write to block 0, the block 1, up to block 15, and then start back over at block 0?
3) For the 15M figure, is it writting to block 0, offset 0, then block 0, offset 1, all the way to block 1, offset 15, and then starting back at block 0, offset 0?
Our application needs to be able to write 12 bytes at least 1M times, so any help is greatly appreciated.
Many thanks for the help.
