PCA2002  
32 kHz watch circuit with programmable output period and  
pulse width  
Rev. 8 — 25 November 2011  
Product data sheet  
1. General description  
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 with a programmable, digital  
frequency adjustment.  
The output period and the output pulse width can be programmed. It can be selected  
between a full output pulse or a chopped output pulse with a duty cycle of 75 %. In  
addition, a stretching pulse can be added to the primary driving pulse.  
A pad RESET is provided (used for stopping the motor) for accurate time setting and for  
accelerated testing of the watch.  
2. Features and benefits  
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 required  
Very low current consumption: typically 90 nA  
Output pulses for bipolar stepping motors  
Five different programmable output periods (1 s to 30 s)  
Output pulse width programmable between 1 ms and 8 ms  
Full or chopped motor pulse and pulse stretching, selectable  
Stop function for accurate time setting and current saving during shelf life  
Test mode for accelerated testing of the mechanical parts of the watch  
Test bits for type recognition  
3. Applications  
Driver circuits for bipolar stepping motors  
High immunity motor drive circuits  
High production volumes  
1. The definition of the abbreviations and acronyms used in this data sheet can be found in Section 15.
