Abstract

In a semiconductor device of related art, the degree of freedom when using one pad with plural functions has been disadvantageously low. A semiconductor device has an internal logic circuit, a regulator circuit, and an interface circuit, and the regulator circuit and the interface circuit are coupled to one shared pad. In the case where a driving transistor of the regulator circuit is controlled to be in a conductive state, the shared pad is used as a terminal to which an input voltage of the regulator circuit is input. In the case where the driving transistor of the regulator circuit is controlled to be in a disconnected state, the shared pad is used as an input/output terminal of the interface circuit.
