ï® Write Protect Function during the Low Power Supply Voltage
The S-24C08C has a built-in detection circuit which operates with the low power supply voltage, cancels Write when the
power supply voltage drops and power-on. Its detection and release voltages are 1.20 V typ. (Refer to Figure 18).
The S-24C08C cancels Write by detecting a low power supply voltage when it receives a stop condition.
In the data trasmission and the Write operation, data in the address written during the low power supply voltage is not
assurable.
