Hi All,
I've a project in mind that requires a couple of values to be saved when the power is off, but I read a quote in a post that the 08M2 will only handle around 10,000 write cycles to EEPROM, which won't be enough.
I've had a look through the datasheet for the 08M2 and it states that the chip itself can be reprogrammed at least 100,000 times, which hints that the above quote is a typo - as a comparison, the 24LC16B serial EEPROM datasheet states "1,000,000 erase/write cycles guaranteed".
Can anyone confirm the lifespan of writing to internal EEPROM on an 08M2?
Additionally, is the quote for a given memory slot, as in if "write 0,b1" and "write 1,b1" were both executed, would each command use one of the 10,000 lives, or is does bytes 0 have 10,000 to use, byte 1 have 10,000, byte 2 have 10,000 etc? If this is the case I can spread the load across individual bytes and not have to resort to using an external EEPROM chip.
Any info glady received
