Systems and methods for providing power to a home entertainment integrated circuit chip are disclosed. The home entertainment integrated circuit chip can operate in at least two power control modes: “power on” mode and “standby” mode. In power on mode, power is supplied to IC core module from a main power supply. The power supplied to the IC core module is isolated from power supplied to a standby island. Accordingly, during the second mode power is applied only to the standby power island through a regulator internal to the integrated circuit chip. The regulator is coupled to an external peripheral input/output (I/O) power supply that is independent of the main power supply.
