Providing a wireless communication device that, even if clock stop of a radio frequency part is controlled by a baseband part operating on the same clock signal, can resume clock oscillation, and makes it easy to time the clock reactivation to other operations based on a shared clock. The wireless communication device comprises an RF part generating a first clock signal and a baseband part. The baseband part generates a second clock signal, controls the generation and stop of the first clock signal, uses the first clock signal to perform data processing and a clocking operation, and in a low power consumption state in which the first clock signal is stopped, uses the second clock signal to perform a timer operation and a clocking operation. The generation timing of the first clock signal can be generated by the timer operation using the second clock signal.
