Procurement Notes

Verify that the specific ordering suffix matches the required feature set, including CAN interface support and package type. Confirm the temperature grade corresponds to the application environment requirements. Ensure compliance with automotive safety standards during integration.

Selection Notes

Select this component for designs requiring high SNR and robust noise suppression in automotive environments. The 103-sense pin configuration allows for larger screen sizes up to 15 inches. Consider the available communication interfaces, including I2C and SPI, when designing the host system connection.

Part Context

This part belongs to the CYAT817X series, which includes variants with different numbers of sense pins such as 61, 72, 77, 88, and 98. The 'AZ' designation indicates a TQFP package, while 'A' specifies the –40°C to 85°C operating temperature range. Other suffixes define specific feature combinations like haptic feedback or proximity sensors.

Replacement Considerations

Direct replacements within the same generation include CYAT817AZS98-5BFFE or CYAT817AZA98-5BFBA, provided the package and temperature ratings are compatible. Verify that any substitute maintains the required number of sense pins and feature set.
