ABSTRACT:
A semiconductor device of the present invention comprises a first step-down voltage circuit to generate a first step-down voltage lower than an externally-supplied power supply voltage, and a second step-down voltage circuit to generate a second step-down voltage lower than the first step-down voltage. The first step-down voltage circuit has a withstand voltage no lower than the power supply voltage and the second step-down voltage circuit has a withstand voltage no lower than the first step-down voltage.
