PCA2000 Product details

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.

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.
