(4) Power on Supply Specifications (Power-on Reset)
(AVSS = VSS = 0.0 V, TA = 0
°C to +70°C)
* : Before the power rising, VCC must be less than 0.2 V.
Note: The above standards are the values needed in order to activate a power-on reset.

It is recommended that the rate of
increase in the voltage be kept to
no more than 50 mV/ms.
If power supply voltage needs to be changed in the course of operation, a smooth voltage rise is
recommended by suppressing the voltage variation as shown below.
