PCF1178C - 4-digit duplex LCD car clock

Datasheet Summary

Description

The PCF1178C 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).

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).
  • 1 Hz set mode.
