• Split-screen display interfaces in automotive dashboards

Touch Screen Controllers Procurement Notes

Verify the specific ordering suffix against the official Infineon datasheet to confirm feature sets such as CAN interface or crypto engine availability. Ensure the selected package matches the required PCB footprint and that the temperature rating aligns with the target application environment.

Touch Screen Controllers Selection Notes

Select this model when seven-seven sense channels are required alongside force touch and hover detection. Confirm compatibility with the host system's communication interface, as the device supports I2C and SPI. Evaluate power consumption requirements against the specified average power of 30 mW and deep sleep current.

Touch Screen Controllers Part Context

This component belongs to the CYAT817X series of PSoC Automotive Multitouch controllers. It is part of the Generation 7XL family designed for high-performance human-machine interfaces in vehicles. The 'S' designation indicates the extended temperature range variant suitable for demanding automotive environments.

Touch Screen Controllers Replacement Considerations

Direct replacements within the same generation include other CYAT817AZS variants with different pin counts or feature sets. Cross-generation upgrades may require firmware adaptation due to architectural differences in the PSoC core.
