An integrated circuit includes a programming circuit ( 10 ) for generating programming signals (PS 1 , . . . , PS 4 ) with a first input terminal (E 1 ) for applying a control voltage (ES), a second input terminal (E 2 ) for applying a reference voltage (Vref), a storage circuit ( 30 ) with programmable switches ( 35, . . . , 38 ) and output terminals (A 1 , . . . , A 4 ). The programming circuit in each case generates a programming signal (PS 1 , . . . , PS 4 ) when the control voltage (ES) exceeds a predefined threshold voltage formed from the reference voltage. The number of programming signals (PS 1 , . . . , PS 4 ) is dependent on the magnitude of the threshold voltage exceeded by the control voltage (ES). The programming signals are used for programming the programmable switches ( 35, . . . , 38 ). The programming state of the programmable switches can be read out via the output terminals (A 1 , . . . , A 4 ) of the integrated circuit. The integrated circuit enables the storage of external operating parameters of the integrated circuit.
