S-24CM01C
ï® Write Protect Function during the Low Power Supply Voltage
The S-24CM01C 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 18).
The S-24CM01C 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.
