Abstract
PURPOSE: To simplify the operation and the function with no installation of the special battery life calling key but by securing the sequential monitor for the life time information of the battery with every push of the specified key.
CONSTITUTION: Control CTR relating the input/output control, the operation and the watch plus battery using period timing circuit CNT are provided to the integrated circuit LSI. Then the earth side and the voltage side of battery BAT are connected to terminals GND and VDD of circuit LSI each, and the branch voltage between capacitor C and resistance R is connected to terminal RES. At the same time, the power cell life of BAT is memorized previously into ROM and in the form of the binary code, and the comparison is always given between the output of circuit CNT and the memory contents of ROM at comparator COP. The comparison result is applied to gate GATE in the level H or L. And when specific all-clear key CK of the key input part is pressed, the input is applied to GATE. Then the state of the battery life is displayed on display unit LCD in the fixed way in combination between the input of the key input part and output CD of comparator COP.
