When initialization is successfully completed by the power-on-clear circuit, the S-24C32C/64C enters the
standby status.
If the power-on-clear circuit does not operate;
The S-24C32C/64C has not completed initialization, an instruction previously input is still valid or an instruction
may be inappropriately recognized. In this case, S-24C32C/64C may perform the Write operation.
The voltage drops due to power off while the S-24C32C/64C is being accessed. Even if the master device is
reset due to the low power voltage, the S-24C32C/64C may malfunction unless the power-on-clear operation
conditions of S-24C32C/64C are satisfied.
When not using this rise time seen in Figure 28, adjust the phase (reset) to reset the internal circuit in the S-
24C32C/64C normally.
_00_H
For example: If the supply voltage = 5.0 V, raise the power supply voltage to 5.0 V within 200 ms.
