A method and device reduces consumption of a microcontroller, allowing the microcontroller to enter into an "active halt" mode in which the central processing unit, the internal peripheral circuits, and a clock tree are deactivated. The main oscillator is operative and delivers an oscillating signal. An internal interruption returns the microcontroller back into the run mode and is generated after a time delay obtained by an internal circuit activated by the oscillating signal.
