ABSTRACT:
A first signal generation circuit generates a signal which rises from the ground level to a second level when a prescribed time elapses after an external supply potential starts to rise from the ground level to a first level. A second signal generation circuit outputs a power-on reset signal which falls when the signal outputted from the first signal generation circuit exceeds a first prescribed level and an internal supply potential for an internal circuit outputted from internal supply potential generation means exceeds a second prescribed level.
