1. A system for communication, the system comprising:
- a set-top-box comprising;
a power supply within the set-top-box;
a first timing module comprising a first switch and low power control circuit comprising a charge retaining device;
power mode memory; and
an integrated circuit in the set-top-box, the integrated circuit comprising a processor, said processor configured to collect, in the power mode memory, information regarding usage patterns of the set-top box,wherein;
the charge retaining device and the power supply are connected in parallel to an external power source via the first switch;
the low power control circuit is operable to control the first switch to control when the set-top-box enters and exits an ultra-low power control (ULPC) mode, wherein the control of the first switch is based on the information regarding the usage patterns in the power mode memory; and
the low power control circuit recharges the charge retaining device using the external power source via said first switch;
a standby processor in an always-on power island, the standby processor coupled to the processor, which is powered down when the set-top-box enters said UPLC mode and is powered up when the set-top-box exits the ULPC mode, the standby processor coupled to a plurality of interface modules that are integrated into different power islands and operable to receive inputs from a source external to the set-top-box during the ULPC mode; and
a second timing module independent of the first timing module and coupled to the processor and the standby processor, said second timing module for controlling the coupling of the power supply to the integrated circuit.
