An application processor includes a central processing unit (CPU), intellectual properties (IPs), a hardware power management unit (PMU) configured to determine whether the application processor is in system idle based on a first idle signal output from the CPU and output control signals as a result of the determination, and a clock signal supply control circuit configured to change an output signal supplied to the CPU and the IPs from clock signals to an oscillation clock signal, based on the control signals. The oscillation clock signal has a frequency lower than that of the clock signals.

A semiconductor device includes a status data signal generating unit receiving a status value of a processor and converting the status value into a status data signal, and a power control signal generating unit generating a power control signal for controlling power supplied from a power management integrated circuit (PMIC), the PMIC supplying power to the processor from outside of processor. The power control signal includes a power off signal for interrupting the power supplied from the PMIC and the status data signal is transmitted to the PMIC together with the power off signal.
