Procurement Notes

Verify the specific suffix 'CU' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing firmware libraries before procurement. Check for end-of-life status or alternative recommendations via authorized distributors.

Selection Notes

Select this component when a high node count with gesture support is required. Compare power consumption metrics against lower-node alternatives if battery life is critical. Verify interface speed requirements match the host processor's I2C or SPI capabilities.

Part Context

This part belongs to the maXTouch family, known for robust touch performance. It complements other controllers in the series by offering higher point counts suitable for larger displays. The CU suffix typically indicates a specific tape-and-reel packaging option for automated assembly.

Replacement Considerations

Check Microchip's official cross-reference guide for direct replacements. Consider the ATMXT224 or ATMXT128 if node count adjustments are acceptable. Verify pinout and register compatibility before substituting.
