Applications

• Automotive infotainment systems
• Vehicle instrument clusters
• Center console control panels

Procurement Notes

Verify the specific ordering suffix against the official Infineon datasheet to confirm feature sets such as CAN interface or cryptographic engine support. Ensure the package type matches the design requirements, as this model utilizes the 128LD TQFP configuration. Confirm temperature grade compliance with system specifications before procurement.

Selection Notes

Select this component for designs requiring high pin counts and advanced gesture recognition. The AZ suffix indicates the TQFP package suitable for surface mount assembly. Verify that the host system can support the required I2C or SPI communication speeds and that the power budget accommodates the specified operating ranges.

Part Context

This part belongs to the CYAT817X series, designed specifically for automotive environments. It offers scalability across different pin counts and feature sets within the Generation 7XL family. The device integrates programmable analog and digital blocks typical of PSoC architectures, allowing for flexible sensor configurations.

Replacement Considerations

Direct replacements within the same family include CYAT817AZS98-5BFBA or CYAT817AZA98-5BFBA. These alternatives share the 103-pin count but may offer additional features like CAN interfaces or haptic feedback support not present in the 42002 variant.
