Product specification
PCF1175C
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.
GENERAL DESCRIPTION
The PCF1175C 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.
