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.
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.
