Philips Semiconductors
32 kHz watch circuits with EEPROM
Product specification
PCA16xx series
FEATURES
32 kHz oscillator, amplitude regulated with excellent
frequency stability
High immunity of the oscillator to leakage currents
Time calibration electrically programmable and
reprogrammable (via EEPROM)
A quartz crystal is the only external component required
Very low current consumption; typically 170 nA
Detector for silver-oxide or lithium battery voltage levels
Indication for battery end-of-life
Stop function for accurate timing
Power-on reset for fast testing
Various test modes for testing the mechanical parts of
the watch and the IC.
GENERAL DESCRIPTION
The PCA16xx series devices are CMOS integrated circuits
specially suited for battery-operated,
quartz-crystal-controlled wrist-watches, with bipolar
stepping motors.
