CYAT817AZA98-5BFBA

Touch Screen Controllers Overview

The CYAT817AZA98-5BFBA is an automotive-grade capacitive touchscreen controller from the PSoC™ Automotive Multitouch Generation 7XL family. It features a 32-bit Arm® Cortex® CPU and supports up to 103 sense pins with ten-finger multitouch capability. 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. Packaged in a 128LD TQFP (14 × 20 × 1.4 mm), it integrates noise-suppression technologies, hover sensing up to 35 mm, force touch, and secondary safety communication interfaces including CAN.

Touch Screen Controllers Feature Summary

• Automotive Electronics Council (AEC)-Q100 qualified for automotive applications
• Supports up to 103 sense pins, reporting up to ten fingers with hover sensing up to 35 mm
• Integrated 32-bit Arm® Cortex® CPU with low-power Deep Sleep mode (30 μW typical)
• Includes force touch, slider sensing, CAPSENSE™ buttons, and wake-up button sensing

Touch Screen Controllers Applications

• Automotive infotainment systems requiring high reliability and AEC-Q100 qualification
• Vehicle instrument clusters and dashboard displays supporting glove and wet-finger operation
• Center console controls utilizing force touch and slider sensing capabilities

Touch Screen Controllers Procurement Notes

Verify the specific ordering suffix against the official Infineon datasheet to confirm feature sets such as CAN interface support or package type. Ensure that the required ambient temperature range matches the 'A' designation (-40°C to 85°C). Confirm firmware compatibility with existing bootloader configurations if field upgrades are planned.

Touch Screen Controllers Selection Notes

Select this component when AEC-Q100 qualification and robust noise immunity in automotive environments are required. The 103-pin configuration allows for larger screen sizes up to 15 inches diagonal. Consider the integrated DSP and auto armor technology if operating near displays with high electromagnetic interference.

Touch Screen Controllers Part Context

This part belongs to the CYAT817X series, which includes variants with different pin counts (61, 72, 77, 88, 98) and feature sets. The 'A' suffix indicates the -40°C to 85°C temperature range, while 'S' denotes -40°C to 105°C. The 'BFBA' suffix typically corresponds to specific interface and security configurations within the 128LD TQFP package.

Touch Screen Controllers Replacement Considerations

Direct replacements within the same family include CYAT817AZS98-5BFBA (discrete sensor variant) or CYAT817AZA98-5B202/5B002 if advanced features like force touch or CAN are not required. Verify pinout and register compatibility before substituting.
