An integrated processing unit is supplied by a power supply voltage present at the terminals of a capacitor configured to supply a maximum permissible voltage drop. A periodic pulse signal is generated having a period that is less than or equal to a current period determined from the maximum permissible voltage drop and a current consumption of the processing unit. The power supply voltage is compared with a threshold voltage at the pulse rate of the periodic pulse signal. A control signal generated from that comparison is delivered to the processing unit and has a first value when the power supply voltage is greater than or equal to the threshold voltage and a second value when the power supply voltage is less than the threshold voltage.
A method for controlling the operation of an integrated processing unit supplied by a power supply voltage present at the terminals of a capacitor, in which a maximum permissible voltage drop at the terminals of the capacitor is defined, comprising:
A device for controlling the operation of an integrated processing unit including a power supply terminal intended to be connected to a power supply input of the power supply terminal, a capacitor connected to the power supply terminal, comprising:
