CYAT817AZA98-5B202

Touch Screen Controllers Overview

The CYAT817AZA98-5B202 is an automotive-grade multitouch capacitive touchscreen controller from the Infineon PSoC™ Automotive Multitouch generation 7XL family. It features a 32-bit Arm® Cortex® CPU and supports up to 103 sense pins with ten-finger tracking. The device operates within a supply voltage range of 1.71 V to 5.5 V and functions in ambient temperatures from -40°C to 85°C (Automotive-A). Key capabilities include hover sensing, force touch, slider detection, and CAPSENSE™ buttons. It integrates noise-suppression technologies, auto armor, and external display synchronization for high signal-to-noise ratios.

Touch Screen Controllers Feature Summary

• Supports up to 103 sense pins and reports up to ten fingers simultaneously
• Includes hover sensing (up to 35 mm), force touch, sliders, and wake-up button sensing
• Features integrated DSP, auto armor technology, and dual sense capability for water rejection
• Provides I2C slave (up to 1 Mbps) and SPI slave (up to 8 Mbps) primary communication interfaces

Touch Screen Controllers Applications

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

Touch Screen Controllers Procurement Notes

Verify that the specific ordering suffix matches the required feature set, particularly regarding the presence or absence of haptic and acoustic outputs. Confirm package availability in the 100LD or 128LD TQFP formats as specified in the official ordering table. Ensure compliance with the Automotive-A temperature rating (-40°C to 85°C) for the target application environment.

Touch Screen Controllers Selection Notes

Select this component when designing systems requiring up to 103 sense pins and ten-finger multitouch support. It is suitable for applications needing hover sensing and force touch capabilities without haptic feedback integration. Consider the 128LD TQFP package for larger sensor arrays. Verify interface requirements against the available I2C and SPI speeds.

Touch Screen Controllers Part Context

This part belongs to the CYAT817X series, which includes variants with different sense pin counts (61, 72, 77, 88, 98, 103) and feature sets. The 'A' suffix indicates the Automotive-A temperature range. Other models in the family may offer additional features such as haptic output, acoustic output, or CAN interface support, which are not present in this specific configuration.

Touch Screen Controllers Replacement Considerations

Direct replacements within the same family include CYAT817AZA98-5B002 and CYAT817AZA98-5BFBA. These parts share the same 103-sense-pin count and package but differ in supported features like haptic or acoustic outputs. Ensure firmware compatibility when switching between these variants.
