How many write cycles can the EEMEM go through before it fails?
After the specified EEMEM data retention timeout period, can the power be turned off and back on so that the part is considered “refreshed”? No. That will only refresh the RDAC register but not the EEPROM. The data will have to be reloaded again after 15 years in order to put a fresh charge into the EEPROM cell. This can be done by writing the RDAC wiper register data back to the EEPROM before the end of 15 years.
