CYAT817AZS98-523DA

Overview

The CYAT817AZS98-523DA is a PSoC™ Automotive Multitouch Generation 7XL capacitive touchscreen controller designed for automotive applications. It features a 32-bit Arm® Cortex® CPU and supports up to 103 sense pins with a maximum of ten fingers. The device operates within an ambient temperature range of –40°C to 85°C (Automotive-A) and utilizes 1.71 V to 1.95 V logic/digital I/Os, 3.0 V to 5.5 V analog supply, and 3.0 V to 5.5 V logic/digital I/Os. It consumes 30 mW average power and 30 μW typical Deep Sleep power.

Feature Summary

• Supports up to 103 sense pins and reports up to ten fingers simultaneously.
• Includes hover sensing, slider sensing, CAPSENSE™ buttons, and low-power wake-up button capabilities.
• Features water rejection, wet-finger tracking, and glove support via dual sense capability.
• Provides secondary safety communication interfaces including CAN, I2C/SPI, and optional cryptographic engine.

Applications

• Automotive infotainment systems
• Driver and passenger display touch interfaces
• Smart sensing applications requiring high reliability

Procurement Notes

Verify the specific ordering suffix '523DA' against official Infineon documentation to confirm feature set alignment, particularly regarding the presence of haptic and acoustic interfaces. Ensure compatibility with the required 100LD or 128LD TQFP package dimensions and pitch specifications during procurement planning.

Selection Notes

Select this component for designs requiring up to 103 sense pins and advanced gesture recognition like sliders and hover. Confirm that the system architecture supports the necessary 3.0 V to 5.5 V analog supply and 1.71 V to 1.95 V digital supply rails. Verify if the secondary CAN interface and cryptographic engine are required for the target application's security standards.

Part Context

This part belongs to the PSoC™ Automotive Multitouch Generation 7XL series, which is AEC-Q100 qualified. The series targets strict automotive quality standards while supporting innovative HMI modes such as force touch and split screens. It integrates noise-suppression technologies for display and EMI compliance.

Replacement Considerations

Other parts in the CYAT817X family offer different pin counts (61, 72, 77, 88) and feature sets. When replacing, ensure the substitute matches the 103-sense-pin requirement and includes the specific secondary SCB and CAN interfaces indicated by the '523DA' suffix.
