Philips Semiconductors
32 kHz watch circuits using a silver-oxide
or a 3 V lithium battery
Product specification
PCA167x series
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.
GENERAL DESCRIPTION
The PCA167x series devices are CMOS integrated circuits
specially suited for battery-operated,
quartz-crystal-controlled wrist-watches, with a bipolar
stepping motor.
