Procurement Notes

Verify the specific suffix (A01 vs A02) against official datasheets as variants may differ in package or revision. Confirm end-of-life status and availability through authorized distributors, as discontinuation notices may apply to this component series.

Selection Notes

Select this part when a dedicated capacitive touch solution with I2C connectivity is required. Ensure the host system supports I2C protocols. Compare input channel requirements against the 12-channel limit to confirm suitability for the target application design.

Part Context

This component belongs to the Silicon Labs TouchXpress family of fixed-function controllers. It complements other CPT1xxS models by providing a standardized interface for capacitive sensing solutions, often paired with 8-bit or 32-bit microcontrollers in embedded systems.

Replacement Considerations

Check for updated revisions within the CPT112S series. Consult Silicon Labs documentation for pin-compatible or functionally equivalent alternatives if the A01 variant is discontinued.
