PCA2002, CMOS

The PCA2002 is a CMOS1 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

PCA2002 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
