Procurement Notes
Verify the specific ordering suffix CCUBRHA1 against official Microchip documentation to confirm tape and reel packaging and RoHS compliance status. Ensure compatibility with system voltage levels and interface protocols before integration. Cross-reference the latest datasheet for any recent product change notices affecting pinout or electrical characteristics.
Selection Notes
Select this component when a high node count is required for large or multi-zone touch surfaces. The choice between I2C and SPI should align with existing system bus architecture and speed requirements. Consider the 88-UFBGA footprint constraints during PCB layout design to ensure adequate thermal and mechanical performance.
Part Context
This part belongs to the ATMXT640 family of touch controllers, designed for advanced gesture recognition and multi-touch capabilities. It integrates signal processing algorithms to enhance sensitivity and noise immunity. The device is part of Microchip's broader maXTouch portfolio aimed at consumer electronics and industrial automation markets.
Replacement Considerations
The ATMXT640UD-CCUR001 serves as a related variant within the same family, differing primarily in packaging configuration. Verify pin-to-pin compatibility and software firmware compatibility when substituting between different packaging suffixes or revision levels.
