Power-on reset is not working. What could be the cause?

Latest Updated:11/22/2016

Question:

Power-on reset is not working. What could be the cause?

Answer:

Power-on reset requires that VCC be 0.9 V or lower for at least 1 ms. Please refer to tw(por) in the figure Power-on Reset Timing in Electrical Characteristics in the User's Manual: Hardware.

Even when connecting a capacitor to the RES# pin to counter noise, please make sure that the voltage of the RES# pin doesn't drop below  0.8Vcc.
For VIH, please see Electrical Characteristics in the User's Manual: Hardware.
