2 / 16 page 1997 Apr 16 2 Philips Semiconductors Product specification 4-digit LCD car clock PCF1171C FEATURES • Driving standard 31⁄2 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). GENERAL DESCRIPTION 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. ORDERING INFORMATION Notes 1. See Fig.1 and Chapter “Package outline” for pin layout and package details. 2. See Chapter “Chip dimensions and bonding pad locations” for pad layout and package details. TYPE NUMBER PACKAGE NAME DESCRIPTION VERSION PCF1171CT VSO40 plastic very small outline package; 40 leads; face down(1) SOT158-2 PCF1171CU − uncased chip in tray(2) − |
