POWER CONSUMPTION REDUCING DEVICE OF LOGIC CIRCUIT MOUNTED DEVICE

摘要

PURPOSE: To reduce the power consumption of the logic circuit mounted device which operates with a system clock. CONSTITUTION: The logic circuit mounted device which operates with the system clock consists of an oscillation stop means consisting of a monostable multivibrator 13 which stops the oscillation of an oscillator X11 for the clock and a switching circuit 14 and a restart means which restarts the oscillation of the clock in response to the generation of the event and includes a time constant circuit resistor R11 and a capacitor C11 provided associatively with the said monostable multivibrator 13.
