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.
