 Write Protect Function during the Low Power Supply Voltage

The S-24C512C 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 1.50 V typ. (Refer to Figure 19).

The S-24C512C 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.
