A microcomputer includes: a CPU executing a predetermined calculation process; and a PWM timer generating a PWM pulse. The PWM timer includes a RAM for storing a duty value of the PWM pulse and a PWM controller for generating the PWM pulse. The PWM controller includes a PWM counter for counting up from a predetermined value as an initial value. The PWM pulse has an unit waveform, which is generated based on comparison between the duty value of the RAM and an output value of the PWM counter. The RAM outputs a new duty value at every comparison without functioning the CPU so that the duty value of the PWM pulse is changed in chronological order.
