Note 6: When the supply voltage VDD is less than 3.0V, the operating temperature Topr must be in a range of −20°C to 85°C.
Note:Care must be taken in system designing since the power-on reset circuit may not fulfill its functions due to the
Note 1: Because the power-on reset releasing voltage and the power-on reset detecting voltage change relative to one another,
Note 2: A clock output by an oscillating circuit is used as the input clock for a warming-up counter. Because the oscillation fre-
