Touch Screen Controllers Procurement Notes

Verify the specific ordering suffix against the official Infineon datasheet to confirm feature sets such as haptic or acoustic support. Confirm that the required package type matches the 100LD TQFP specification. Ensure environmental compliance requirements align with the product's RoHS status before procurement.

Touch Screen Controllers Selection Notes

Select this model when six sense pins are sufficient for the target display size. Verify if hover sensing and ten-finger multitouch are required features. Check if the -40°C to 85°C temperature range meets the application's operational needs. Consider alternative pin counts if more sensor channels are necessary.

Touch Screen Controllers Part Context

This component belongs to the PSoC Automotive Multitouch Generation 7XL series. It shares common base features like water rejection and auto armor technology with other models in the family. The part number indicates a discrete sensor configuration designed for automotive markets.

Touch Screen Controllers Replacement Considerations

Direct replacements must match the 100LD TQFP package and 61-sense-pin configuration. Models like CYAT817AZS61-3A002 offer similar functionality but may lack specific interface options. Verify firmware compatibility and electrical specifications before substitution.
