Motorola's MC1440 CMOS integrated circuit has the functions of completion time, display calendar. 32.768KHZ NT cut-type quartz crystal and fine-tuning capacitor can generate time-base signal. The monitor circuit only uses 1.5V AAA battery, and the watch circuit can work more than one year, and accuracy is less than the ± 1min. The voltage tripler composed of MBD101 Schottky diode can switch the 1.5V battery output voltage into 4V for the LCD monitor.
