PCA2000 Features

* Amplitude-regulated 32 kHz quartz crystal oscillator, with excellent frequency stability and high immunity to leakage currents

* Electrically programmable time calibration with 1 ppm resolution stored in One Time Programmable (OTP) memory

* The quartz crystal is the only external compo

PCA2000 General Description

The PCA2000 and PCA2001 are CMOS1 integrated circuits for battery operated wrist watches with a 32 kHz quartz crystal as timing element and a bipolar 1 Hz stepping motor. The quartz crystal oscillator and the frequency divider are optimized for minimum power consumption. A timing accuracy of 1 ppm i.
