topGeneral description
The PCF1172C is a single chip, 4.19 MHz CMOS clock circuit indicating hours and minutes. It is designed
to drive a 3 1/2 -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.
