Product specification
32 kHz watch circuits with adaptive motor
pulse
PCA146x 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
Output for bipolar stepping motors of different types
Up to 50% reduction in motor current compared with
conventional circuits, by self adaption of the motor pulse
width to match the required torque of the motor
No loss of motor steps possible because of on-chip
detection of the induced motor voltage
Detector for lithium or silver-oxide 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 PCA146x series devices are CMOS integrated circuits
specially suited for battery-operated,
quartz-crystal-controlled wrist-watches, with a bipolar
stepping motor.
