Fig. 2 Maximum power-voltage activation time
Initialize time tinit
The EEPROM is instantly initialized when the power voltage is activated.
Since the EEPROM does not accept commands during initialization, the transmission of commands
to the EEPROM must be started after this initialization time period.
Fig. 3 shows the time required to initialize the EEPROM.
*1 At 0 V, there is no potential difference
between the VCC and GND terminals of
the EEPROM.
*2 t.nit is the time required for EEPROM to
initialize internally. During this time period,
the EEPROM will not accept commands.
Example) If the operating power voltage is
5 V, ensure that the power voltage reaches
5 V within 20.0 ms.
