Abstract
In an integrated circuit, a detection device detects a drop in the supply voltage of the core of the integrated circuit or an excessively slow build-up of this voltage with respect to a supply voltage of the input/output interface circuits of the integrated circuit. Outputs of the interface circuits are set to a high impedance state by the detection device to minimize their power consumption.
