ABSTRACT:
A semiconductor device includes a first circuit block which operates on a first power supply voltage to output a first digital signal having an amplitude equal to that of the first power supply voltage, a level shifting circuit into which the first digital signal is input and which converts the amplitude of the first digital signal to an amplitude equal to that of a second power supply voltage to output as a second digital signal via an output terminal, a second circuit block which operates on the second power supply voltage and into which the second digital signal is input, and a monitor circuit which produces a first signal to set the output terminal of the level shifting circuit to a predetermined potential in a case where the first power supply voltage drops below a predetermined voltage level.
