INTEGRATED CIRCUITS DATA SHEET PCF1171C 4-digit LCD car clock Product specification Supersedes data of September 1993 File under Integrated Circuits, IC16 1997 Apr 16 Philips Semiconductors Product specification 4-digit LCD car clock FEATURES · Driving standard 31/ 2 PCF1171C GENERAL DESCRIPTION or a 4-digit LCD · Internal voltage regulator for 5 V LCD · Option for external stabilized voltage supply · 4.19 MHz oscillator · Integrated oscillator output capacitor and polarization resistor · Operating ambient temperature: -40 to +85 °C · 40-lead plastic SMD, face down (VSO40). ORDERING INFORMATION TYPE NUMBER PCF1171CT PCF1171CU Notes The 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. A bonding option allows the selection of 12-hour or 24-hour display mode. The circuit is battery-operated via an internal 5 V voltage regulator or by an external stabilized voltage supply.
