PCF1171C is a single chip, 4.19 MHz CMOS car clock circuit indicating hours and minutes. It is designed to drive a 31/2 or 4-digit liquid crystal display (LCD). 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.
The Philips PCF1171C is a single-chip, 4.19 MHz CMOS car clock circuit designed to drive a 31% or 4-digit liquid crystal display (LCD). It indicates hours and minutes and includes an internal voltage regulator for 5 V LCD operation or an option for an external stabilized voltage supply. The circuit is battery-operated and features integrated oscillator output capacitor and polarization.
