In a microprocessor based system, wherein at least one microprocessor is battery powered, a power strobe circuit includes an analog switch for connecting the battery to the microprocessor only during programmed task performance. Upon completion of task performance, the microprocessor generates signals which trigger the analog switch to open, thereby deenergizing the microprocessor and to enable an external timer. After a predetermined period of time, which may be fixed in the timer or programmed, the timer causes the switch to reclose, thereby energizing the microprocessor for performance of another programmed task.
