Abstract
A semiconductor device that prevents malfunction in an external circuit by preventing an indefinite signal from being output at the time of power being applied. A processing circuit is supplied with an internal power supply voltage from an internal power supply voltage generating circuit and performs a predetermined process. An output circuit outputs the result of processing by the processing circuit. When the supply of an external power supply voltage is begun, a control circuit exercises control so that output from the output circuit will be kept in a predetermined state. A supply circuit supplies an external power supply voltage to the control circuit.
