ABSTRACT:
An electronic device includes an integrated circuit operating on the basis of an operating clock signal, an error detection circuit and a control circuit coupled to the error detection circuit. The control circuit is configured to increase the frequency of the operating clock signal starting from a nominal operating frequency of the integrated circuit, to evaluate a frequency increment at which an error is detected by the error detection circuit, and to reset the frequency of the operating clock signal to said nominal frequency.
