Write Protect Function during the Low Power Supply Voltage
The S-7760A 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 voltage is 1.75 V (Typ.) and the release voltage is 2.05 V (Typ.),
and its hysteresis is approx. 0.3 V.
The S-7760A cancels Write by detecting a low power supply voltage when it receives a stop condition.
Both in the data transmission and the Write operation, data in the address written during the low power supply voltage is
not assured.
