Title: Timer circuit
Inventor: SASAKI KAZUO
IPC: G04F1/00
Filed: 1989-03-13
Abstract: PURPOSE:To reduce the power consumption as the entire timer circuit by providing a storage circuit to a 1st circuit section and a reference voltage circuit to a 2nd circuit section and resetting the storage circuit accordingly when the counter of the 2nd circuit section counts up. CONSTITUTION:A pulse signal is oscillated from an oscillator 22 and a counter 23 counts the pulse signal. When a countup signal of the counter 23 is outputted, an output of an AND gate goes to H and the H signal is fed to a reset terminal of a flip-flop 9 via an OR gate 7. When the flip-flop 9 is reset again, a reference voltage circuit 21 interrupts a reference voltage V. Thus, no voltage is supplied to each circuit of a 2nd block B and no power consumption will be caused. That is, only when a timer signal is outputted, a power supply is supplied and no power is supplied normally, then the power consumption in the 2nd block B is much decreased.
