Procurement Notes

Verify the complete part number including suffixes such as 'CCUR035' against official Microchip documentation to ensure correct package type, tape & reel configuration, and automotive qualification status. Confirm lead times and availability through authorized distributors as stock levels vary.

Selection Notes

Select this component when high node count and automotive reliability are required. Ensure the host system supports the desired interface protocol (I2C/SPI/USB). Verify that the display size and resolution align with the 1664-node capacity. Check mechanical constraints for the available packages, typically UFBGA or similar high-pin-count formats.

Part Context

This part belongs to the maXTouch family of touchscreen controllers from Microchip. The maXTouch series is widely used in consumer electronics and automotive displays due to its robust performance and configurability via the maXTouch Studio software tool. The 1664-node variant targets larger screens requiring finer touch granularity.

Replacement Considerations

Check Microchip's official cross-reference list for direct replacements. Consider other maXTouch models like ATMXT224 or ATMXT336 if node count requirements differ. Ensure pin compatibility and firmware configuration files are available for any substitute parts.
