Action of Circuit for Prevention Malfunction by Low Voltage
The S-7750C has a detection circuit which works with the low power supply voltage, cancels Write in order to reset the
internal circuit when power-on and the power supply voltage is dropping. When the power supply voltage is restored and
exceeds the level of release voltage, the S-7750C automatically reloads command. The detection voltage is 1.75 V typ.,
the release voltage is 2.05 V typ., its hysteresis width is approx. 0.3 V. Refer to Figure 30.
The S-7750C 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.
