t 8 ms Debounce time 1 t 1 sec Manual to auto scan time 2 t 140 ms Auto scan step 3 t 4 ASE = 0 V, PD = GND, PU = GND 1 sec Auto save execute time t 8 ms Low pulse time to manual storage 5 ASE = VDD t 1 15 50 ms Memory program time EEPROM_PROGRAM t 2 50 µs Power-on EEPROM restore time POWER_UP 1 EEPROM program time depends on the temperature and EEPROM write cycles. Higher timing is expected at a lower temperature and higher write cycles. 2 Maximum time after VDD is equal to 2.3 V.
