描述 Description

GENERAL DESCRIPTION
The PCF1179C is a single chip, 4.19 MHz CMOS car clock circuit providing hours, minutes and seconds functions. It is designed to drive a 4-digit duplex liquid crystal display (LCD).
Two external single-pole, single-throw switches will accomplish all time setting functions. Time calibration and voltage regulator are electrically programmable via an on-chip EEPROM. The circuit is battery-operated via an internal voltage regulator and an external resistor.FEATURES
• Internal voltage regulator is electrically programmable for various LCD voltages
• Time calibration is electrically programmable (no trimming capacitor required)
• LCD voltage adjusts with temperature for good contrast
• 4.19 MHz oscillator
• 12-hour or 24-hour mode
• Operating ambient temperature: −40 to +85 °C
• 28-lead plastic SMD (SO28)
• 4 Hz set mode.
