The Motorola company's MC14440 CMOS integrated circuit has the function of timing and displaying the calendar. The 32.760 kHz NT cutting type quartz crystal and fine-tune capacitance can produce time-based signal.The display circuit only uses 1.5 V AAA battery, watch circuit can workfor more than one year, the accuracyof it is within ±1min.The voltage tripler which is composed of the schottky diode MBD101, can transform the 1.5 V battery output voltage to 4V, supply to LCD using.
