32 kHz watch circuit with programmable output period and pulse width

The PCA2002 is a CMOS integrated circuit for battery operated wrist watches with a 32 kHz quartz crystal as the timing element and a bipolar stepping motor. The quartz crystal oscillator and the frequency divider are optimized for minimum current consumption. A timing accuracy of 1 ppm is achieved w Amplitude-regulated 32 kHz quartz crystal oscillator, with excellent frequency stability and high immunity to leakage currents\nElectrically programmable time calibration with 1 ppm resolution stored in One Time Programmable (OTP) memory\nThe quartz crystal is the only external component required\nV;
