PCF2003 Product details

Description

The PCF2003 is a CMOS integrated circuit for battery operated wrist watches with a 32 kHz quartz crystal as timing element and a bipolar 1 Hz stepping motor.

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 supply current, typical 90 nA.
One second output pulses for bipolar stepping motor.
Five different programmable output periods (1 s to 30 s).
Minimum power.
