摘要： A circuit with switchable functionality has a first integrated circuit, which has, in a first operating mode, full functionality and which has, in at least one other operating mode, a functionality which is reduced in comparison with the full functionality. The circuit further has an output terminal to which a coupling element can be coupled, an identification device which identifies whether a first supply potential has been applied to the output terminal via the coupling element and in this case produces a status signal with a first value and otherwise produces a status signal with a second value, a setting device, which sets the full or reduced functionality as a function of the value of the status signal in the first integrated circuit. The invention also relates to an electronic component having such a circuit arrangement.
