The 2313 data sheet states:
Endurance: 100,000 Write/Erase cycles
for the 128 bytes of eeprom.

Does this figure refer to eeprom accesses in total, or is it accesses to individual bytes?

Hi Colin

EEPROM write cycles are generally specified per cell. So you get 100,000 writes to each cell. If you feel you're going to run out and are only storing a few bytes, keep a pointer to a counter in EEPROM as well and after 100,000 cycles, start writing a bit further into the the address space. Once you've used the whole EEPROM however, you'll have to change your processor!
