PCA1487U/10規(guī)格書詳情
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 in accordance with the required torque of the motor
· No loss of motor steps possible because of on-chip
detection of the induced motor voltage
· 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 PCA148x series devices are CMOS integrated circuits
specially suited for battery-operated,
quartz-crystal-controlled wrist-watches, with a bipolar
stepping motor.
