The oscillator with cycle time correction includes a low accuracy oscillator A generating a clock CLK , a counter counting the clock CLK and cleared by activation of a clear signal CLR , a register storing a count CN of the counter as a reference value RV in response to activation of a capture signal CAP; a comparator activating a coincidence signal EQ when CN&equals;RV, a control register including a bit outputting a clear signal CLR , a bit outputting an enable signal EN and a bit outputting a capture signal CAP, and logic circuits and activating the clear signal CLR when the clear signal CLR is active or when the enable signal EN and the coincidence signal EQ are both active.
