GENERAL DESCRIPTION
The PCF1172C is a single chip, 4.19 MHz CMOS clock
circuit indicating hours and minutes. It is designed to drive
a 312-digit liquid crystal display (LCD) with AM and PM
indicators.
Two external single-pole, single-throw switches will
accomplish all time setting functions. The circuit is
battery-operated via an internal 5 V voltage regulator or by
an external stabilized voltage supply.
