Abstract
An integrated circuit includes a microprocessor driven by an internal clock signal and at least one internal peripheral circuit activated selectively by the microprocessor to perform an operation, wherein said circuit includes a circuit for matching the period of the internal clock signal to the operating time of the activated internal peripheral circuit. The integrated circuit can be used as part of any microcontroller.
