- Human-machine interface controllers requiring I2C or SPI connectivity
- Portable electronic devices operating within specified voltage and temperature ranges
Procurement Notes
Verify the specific ordering suffix against official Microchip documentation to ensure correct package and tape-and-reel specifications. Confirm RoHS3 compliance status and moisture sensitivity level (MSL 3) requirements during storage and handling. Check for any recent Product Change Notifications regarding packaging label updates before procurement.
Selection Notes
Select this component when a two-wire capacitive solution with flexible I2C/SPI interface options is required. Ensure the system power supply aligns with the 1.71V–3.47V operational range. Verify that the PCB layout accommodates the 88-UFBGA footprint and that thermal management supports the -40°C to +85°C operating environment.
Part Context
This part belongs to the ATMXT640 family of touchscreen controllers. The base model ATMXT640 offers core touch processing capabilities, while the UD-CCU001 suffix denotes specific package, temperature, and environmental compliance variations. It serves as a dedicated controller for interpreting touch inputs on capacitive panels.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Microchip's official cross-reference tools or datasheets for potential alternatives within the maXTouch portfolio.
