PCF1174C - 4-digit static LCD car clock

Description

The PCF1174C 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 static 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.
  • 40-lead plastic SMD, face down (VSO40).
