Zusammenfassung:	A device (102) is provided that includes a chip (110) having a processor (112) and wake -up logic (116). The device also includes power management circuitry (108) coupled to the chip. The power management circuitry selectively provides a core power supply and an input/output (I/O) power supply to the chip. Even if the power management circuitry cuts off the core power supply to the chip, the wake-up logic detects and responds to wake-up events based on power provided by the I/O power supply. L'invention concerne un dispositif (102) comprenant une puce (110) présentant un processeur (112) et une logique d'éveil (116). Ce dispositif comprend également un circuit de gestion de puissance (108) relié à la puce. Le circuit de gestion de puissance fournit sélectivement une alimentation principale et une alimentation entrée/sortie (E/S) à la puce. Même si le circuit de gestion de puissance coupe la puissance principale arrivant à la puce, la logique d'éveil détecte des événements d'éveil et réagit en conséquence en fonction de la puissance fournie par l'alimentation E/S.
