Product Details
PCA2002U/10AB/1,00 - Programmable Watch Motor-Drive Circuit
NXP PCA2002U/10AB/1,00 is an eight-pad wire-bond die for 32 kHz quartz watch timing and bipolar stepping-motor drive with programmable output period and pulse width.
Technical details follow the NXP PCA2002 product data sheet, Rev. 9. Confirm the exact orderable code, lifecycle and OTP settings before assembly or design use.
Overview
The PCA2002 is a CMOS watch circuit combining an amplitude-regulated 32 kHz quartz oscillator, digital time calibration and bipolar stepping-motor output. Its motor output period, pulse width, full or chopped waveform and optional pulse stretching are configured in one-time-programmable memory.
Key Advantages
Selectable output interval
Five programmed motor-pulse periods support different watch-mechanism timing requirements.
Motor waveform options
Programmable width, full or 75% chopped output and optional stretching help match the bipolar motor.
Fine time calibration
Digital adjustment stored in OTP memory permits frequency trimming of the assembled watch.
Low current
Supply current between motor pulses is 90 nA typical under NXP's stated reference conditions.
Feature Summary
Quartz timing
Amplitude-regulated 32 kHz oscillator and programmable digital time correction.
Pulse periods
Output can be programmed for 1, 5, 10, 20 or 30 seconds.
Pulse shaping
OTP selections cover 0.98 to 7.8 ms pulse widths, full or chopped drive and optional stretching.
Stop and test
RESET pad can stop the motor for time setting or invoke an accelerated mechanical test mode.
Package & Footprint
Manufacturer form: PCA200xU wire-bond die with eight bonding pads. NXP's ordering table gives a 1.16 × 0.86 mm die and a 0.22 mm stated upper thickness; the bare-die outline gives 0.20 mm nominal thickness. The exact PCA2002U/10AB/1,00 ordering option is sawn wafer on Film Frame Carrier (FFC).
- Use NXP's PCA2002U pad locations and die outline for wire-bond layout.
- The substrate is connected to VSS; leave the die pad floating or connect it to VSS.
- Leave the internally connected test pad open in normal operation.
A standard molded-package JPG is not applicable to this bare die. Confirm FFC handling, die attach and ESD controls for the production process.
Pin Functions
The numbers below identify bonding pads, not molded-package leads.
Verify active-side orientation and pad coordinates from NXP's drawing before bonding.

Values depend on quartz characteristics, the data-sheet test setup and programmed OTP state.
Replacement Considerations
Other PCA200x family devices have different motor-control functions and are not automatically interchangeable. Verify bond-pad geometry, carrier, output-period choices, waveform, OTP settings, supply range, lifecycle and assembly process before considering another device. No drop-in equivalence is asserted.
Manufacturer Information
The product record identifies NXP USA Inc. NXP's PCA2002 product data sheet, Rev. 9 (6 December 2019), lists the exact /10AB/1,00 orderable code, electrical characteristics and FFC form. NXP discontinuation notification 202509010DN names the same code for full withdrawal; confirm current lifecycle before design-in.
Applications
Battery-operated wristwatches
Quartz timing and configurable bipolar stepping-motor pulse generation.
Wire-bond watch modules
Die-level assemblies requiring post-assembly timing calibration and selected motor waveforms.
Quality & Authenticity
Match the full ordering code, PC2002-1 marking, FFC form, traceability and die condition to purchasing and incoming-inspection records. Follow NXP bare-die handling and ESD guidance. This description does not certify any particular lot or continued availability.
FAQ
Is PCA2002U/10AB/1,00 a packaged eight-pin IC?
No. It is an eight-pad wire-bond die supplied as sawn wafer on a film-frame carrier.
Can the motor pulse interval be selected?
Yes. The OTP options are 1, 5, 10, 20 and 30 seconds; verify the programmed state of the device used.
Is this code suitable for a new design?
NXP has listed this exact code for full withdrawal. Check lifecycle and sourcing before selection.
Engineering Notice
Use manufacturer-controlled data for final decisions. Validate oscillator loading, selected motor interval and pulse width, OTP calibration, pad layout, substrate connection and lifecycle status before product release.
