(4) Power on Supply Specifications (Power-on Reset)
(VCC = 2.7 V to 3.6 V, VSS = 0.0 V, TA = –40
°C to +85°C)
* : When the power rising, VCC must be less than 0.2 V.
Notes :
The above standards are the values needed in order to activate a power-on reset.
Activate a power-on reset by turning on the power supply again this in device.
VCC = VCC1 = VCC2

It is recommended that the rate of
increase in the voltage be kept to
no more than 50 mV/ms.
Abrupt changes in the power supply voltage may cause a power-on reset.
When changing the power supply voltage during operation, suppress variations in the voltage and
ensure that the voltage rises smoothly, as shown in the following figure.
