CYAT817AZS72-33002

Touch Screen Controllers Overview

The CYAT817AZS72-33002 is a capacitive touchscreen controller from the PSoC™ Automotive Multitouch Generation 7XL family. It features a 32-bit Arm® Cortex® CPU and supports up to ten fingers with hover sensing capabilities reaching 35 mm. The device includes force touch functionality, low-power wake-up buttons, and slider sensing. It operates within an ambient temperature range of –40°C to 85°C (Automotive-A). Power supply requirements include 1.71 V to 1.95 V for logic/digital I/Os and 3.0 V to 5.5 V for analog supplies.

Touch Screen Controllers Feature Summary

• Supports up to 72 sense pins and reports up to ten fingers simultaneously
• Includes Force Touch capability with a typical range of 0.5 N to 10 N
• Features low-power wake-up button sensing consuming less than 50 µA
• Provides secondary safety communication interface via CAN

Touch Screen Controllers Applications

• Automotive infotainment systems requiring multi-touch interaction
• Vehicle instrument clusters with force feedback integration
• Center console controls utilizing slider or button sensing

Touch Screen Controllers Procurement Notes

Verify that the application environment remains within the specified Automotive-A temperature limits of –40°C to 85°C. Confirm power supply rails match the required 1.71–1.95 V digital and 3.0–5.5 V analog specifications. Ensure firmware compatibility with the Generation 7XL architecture before procurement.

Touch Screen Controllers Selection Notes

Select this model when exactly 72 sense pins are required alongside Force Touch and low-power wake-up features. Choose the AZ suffix for TQFP packaging and A suffix for the –40°C to 85°C operating range. Consider higher pin counts if more than 72 electrodes are needed for larger screens.

Touch Screen Controllers Part Context

This component belongs to the Infineon PSoC™ Automotive Multitouch Generation 7XL series. It is designed specifically for automotive human-machine interfaces, offering high noise immunity and support for various sensor types including glass and plastic substrates.

Touch Screen Controllers Replacement Considerations

The CYAT817AZS72-3B002 serves as a direct alternative but lacks Force Touch capability. Other variants in the 7XL family may offer different pin counts or additional safety interfaces like CAN.
