PCA1605 - CMOS

General Description

PCA16xx series 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.

Key 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.
  • Detector for silver-oxide or lithium battery voltage levels.
  • Indication for battery end-of-life.
