CYAT847AZA61-22002

Touch Screen Controllers Overview

The CYAT847AZA61-22002 is a PSoC™ Automotive Multitouch Generation 7XL slave controller designed for multi-chip capacitive touchscreen systems. It features a 32-bit Arm® Cortex® CPU and supports up to 61 sense I/Os in a 100-pin TQFP package. The device operates with a 3.0 V to 5.5 V analog supply and 3.0 V to 5.5 V logic/digital I/O supply, consuming approximately 260 mW in a 3-chip solution configuration. It supports screen sizes up to 35 inches diagonal with a refresh rate up to 120 Hz and reports up to ten fingers.

Touch Screen Controllers Feature Summary

• Multi-chip capacitive touchscreen controller with register-configurable 32-bit Arm® Cortex® CPU
• Supports up to 61 sense pins and reports up to ten fingers with thin glove (≤1-mm) support
• Integrated AutoArmor technology for electromagnetic emission and immunity improvement
• DualSense technology enabling water rejection and wet-finger tracking

Touch Screen Controllers Applications

• Automotive infotainment systems requiring large display support
• Multi-chip capacitive touchscreen implementations
• Applications demanding high noise suppression for display and EMI environments

Touch Screen Controllers Procurement Notes

Verify the specific ordering suffix against the official Infineon datasheet summary to confirm pin count, package type, and temperature range. Ensure compatibility with the master controller in a multi-chip architecture. Confirm that the 100-pin TQFP package meets the design constraints for the target application.

Touch Screen Controllers Selection Notes

Select this slave controller for multi-chip setups supporting screens up to 35 inches. It provides 61 sense channels suitable for smaller segments of larger displays. Verify system power requirements, as it operates within a 3.0 V to 5.5 V analog supply range. Consider the 120 Hz maximum refresh rate and 1 Mbps I2C interface speed for system timing.

Touch Screen Controllers Part Context

This component belongs to the PSoC™ Automotive Multitouch Generation 7XL family, specifically the multi-chip variant. It functions as a slave unit in conjunction with master controllers to handle large-area touch sensing. The series is AEC-Q100 qualified and designed for automotive-grade reliability.

Touch Screen Controllers Replacement Considerations

Direct replacements within the same generation include other CYAT847X variants with different sense pin counts (e.g., CYAT847AZA72-22002 for 72 pins). Cross-generation upgrades may require architectural changes due to multi-chip dependencies.
