📥 Download Datasheet

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 is achieved with a programmable, digital frequency adjustment.

Overview

PCA2000; PCA2001 32 kHz watch circuit with programmable adaptive motor pulse Rev.

9 — 24 November 2011 Product data sheet 1.

Key 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 component connected.
  • Very low power consumption, typical 90 nA.
  • One second output pulses for bipolar stepping motor.
  • Minimum power consumption for the entire watch, due to self adaptation of.
