Procurement Notes
Verify the specific suffix 'CU-S' against official Microchip documentation to confirm exact tape-and-reel packaging details and RoHS compliance status. Ensure the ordering part number matches the required package variant and environmental rating before procurement.
Selection Notes
Select this component when a 44-pin interface is required for complex touch button arrays or slider configurations. Confirm that the system design accommodates the 10x10mm TQFP footprint and that the 16 MHz clock speed meets the processing requirements for the intended touch sensing algorithm.
Part Context
This part belongs to the AT42QT5xxx series of capacitive touch controllers. These devices utilize QTouch technology for high-noise immunity and are designed to replace mechanical switches in modern electronic designs, offering long-term reliability and reduced bill-of-materials complexity.
Replacement Considerations
Check Microchip's official obsolescence notices for the AT42QT5480 series. Potential replacements may include newer members of the QTouch family with updated pinouts or enhanced features; verify compatibility through official cross-reference tools.
