Touch Screen Controllers Procurement Notes

Verify component authenticity through authorized Infineon distributors or the MyICP platform. Confirm that the ordering suffix matches the required feature set, as variations exist within the CYAT817X series. Ensure compliance with automotive quality standards and check for updated datasheet revisions before procurement.

Touch Screen Controllers Selection Notes

Select this model for applications requiring AEC-Q100 qualification and advanced gesture recognition. The 88-sense pin configuration supports screen sizes up to 15 inches. Consider the AZ package type (TQFP) and the A temperature rating (-40°C to +85°C) when designing for specific environmental constraints.

Touch Screen Controllers Part Context

This component belongs to the PSoC™ Automotive Multitouch Generation 7XL series, designed for human-machine interface (HMI) in vehicles. It integrates processing capabilities with touch sensing, reducing system complexity compared to discrete solutions. The part number indicates the 88-pin variant with standard automotive temperature ratings.

Touch Screen Controllers Replacement Considerations

Direct replacements within the same generation include CYAT817AZS88-5BFBA (Sensor-on-Lens package) or CYAT817AZA98-5BFBA (103 sense pins). Verify pin compatibility and firmware requirements when substituting between different sense pin counts or package types.
