RE: ATmega88PA EEPROM Memory Life
2012-12-12 by Benny Smith
The Mega88PA data sheet gives the EEPROM a write/erase lifetime of 100,000 cycles. I assume that this applies byte-by-byte to the EEPROM contents. In other words, I assume that if only one of the 88PA's 512,000 EEPROM bytes is changed, then only that byte (i.e., its 8 memory-bit locations) has used up one of its 100,000 cycles. All other EEPROM bytes, which were not changed, still have their full lifetime of 100,000 cycles available. So, if I wanted to save a byte frequently, I could use up the 100,000 cycles at one byte address and then switch to another byte address to store the next 100,000 repetitions of my byte-save operation. Is that correct? Thanks, Benny Smith Inchworm Solutions LLC Santa Rosa, CA [Non-text portions of this message have been removed]
