1
During power-up, the output is momentarily preset to midscale before restoring EEPROM content.
2
Delay time after power-on preset prior to writing new EEPROM data.
3
Endurance is qualified to 100,000 cycles per JEDEC Std. 22 Method A117 and is measured at 40°C, +25°C, and +85°C; typical endurance at +25°C is 700,000 cycles.
4
Retention lifetime equivalent at junction temperature (TJ) = 55°C per JEDEC Std. 22, Method A117. Retention lifetime based on an activation energy of 0.6 eV derates
with junction temperature.
