FUNCTION

I CP is the voltage control capacitor positive pin.

CN is the voltage control capacitor negative pin.

A 0.1 µF capacitor is connected between these two pins.

O COM1 to COM4 are the common signal output terminals for the

1/4 duty LCD.

O SEG1 to SEG32 are the 16-digit segment signal outputs.

I, O A quartz crystal oscillator provides an RTC frequency time base

of 32.768 KHz.

I Either VRTC1 should be connected to a 1.5V battery and VRTC2

should be connected to a capacitor 0.1 µF, which supplies the

power source for the RTC.

I Power input pins.
