GENERAL DESCRIPTION

The PCF1179C is a single chip, 4.19 MHz CMOS car clock

circuit providing hours, minutes and seconds functions.

It is designed to drive a 4-digit duplex liquid crystal display

(LCD).

Two external single-pole, single-throw switches will

accomplish all time setting functions. Time calibration and

voltage regulator are electrically programmable via an

on-chip EEPROM. The circuit is battery-operated via an

internal voltage regulator and an external resistor.
