PCA1676 - CMOS

Datasheet Summary

Description

The PCA167x series devices are CMOS integrated circuits specially suited for battery-operated, quartz-crystal-controlled wrist-watches, with a bipolar stepping motor.

Features

32 kHz oscillator, amplitude regulated with excellent frequency stability.
High immunity of the oscillator to leakage currents.
Very low current consumption; typically 150 nA.
Stop function for accurate timing.
Chopped motor pulses available.
Power-on reset for fast testing.
Various test modes for testing the mechanical parts of the watch and the IC.
