Power-On Reset Circuit and Voltage Detection Circuit Characteristics

Note:

These characteristics apply when noise is not superimposed on the power supply. When a setting is made so that the voltage

detection level overlaps with that of the voltage detection circuit (LVD2), it cannot be specified which of LVD1 and LVD2 is used

for voltage detection.
