Power management system, system on chip including the same and mobile device including the same

The power management system includes a plurality of programs of the nano-controllers, memory, and an instruction signal map memory. Instruction memory stores instructions used by the nano-controller, and is shared by the nano-controller. Signal Map memory stores a plurality of the signal to be controlled by the nano-controller, and is shared by the nano-controller. The first nano-controller is programmed as the central sequencer, the second to n (n is a natural number of 2 or more) nano controllers are programmed as the first sub-sequencer which is dependent on the first nano controller.
