6.8. POR & LVD : Condition for power notch
Power-on-reset is independent of power-rising slope.
The cases of reset generation by VDD notch
Voltage
Voltage
VDD
When VDD fails for a short time, the duration of notch (T) has limitation like
above for the successful POR operation.
The duration (T) will be changed by the VDD value and the transition time
VDD=2V
Power slope = 0.25 V / 1 us
Power slope = 1.0 V / 1 us
T >10us
0V
T > 20us
0.5V

Yellow Region : Only RC-POR operates.
Blue Region
Green Region : Both POR's operate at the same time.
T > 40us
: Only LVD-POR operates.
