ABSTRACT:
The present invention relates to a mobile apparatus comprising an integrated circuit to operate predefined functions, which integrated circuit is susceptible to be set in a standby operating mode wherein which said circuit can resume operation within a predefined delay. The circuit comprises configuration sequential logic having defined states that need to be stored before the circuit enters in standby mode. The mobile apparatus further comprises a power down unit for storing the states of the configuration sequential logic into a low leakage storage area during standby mode that reduces standby current considerably.
