CYAT827AZA59-22002

Touch Screen Controllers Overview

The CYAT827AZA59-22002 is an automotive-grade, multi-touch capacitive touchscreen controller from Infineon's PSoC™ Automotive Multitouch Generation 7XL family. Designed for hybrid in-cell sensor configurations, it features a 32-bit Arm® Cortex® CPU and supports up to 59 receive channels with 16:10 aspect ratio compatibility. The device operates on dual power supplies (1.71–1.95 V digital/logic; 3.0–5.5 V analog) and communicates via I²C at 100 or 400 kbps. It is housed in a 100-pin TQFP package and qualified under AEC-Q100 standards.

• Supports hybrid in-cell sensors with 59 RX channels and integrated DSP
• Includes AutoArmor for electromagnetic emission/immunity improvement and DisplayArmor for noise suppression
• Enables ten-finger multitouch with thin glove support (≤1 mm), water rejection, and nail tracking

Touch Screen Controllers Applications

• Automotive infotainment systems
• Vehicle instrument clusters
• In-car navigation displays

Touch Screen Controllers Procurement Notes

Verify the specific ordering suffix 'A' against the datasheet table to confirm feature sets such as gesture touch-screen capabilities. Confirm the temperature grade corresponds to the required automotive environment (-40°C to 85°C). Ensure the host system supports the specified I²C interface speeds and voltage levels for reliable communication.

Touch Screen Controllers Selection Notes

Select this model for applications requiring hybrid in-cell sensor integration with up to 59 receive channels. Compare with the 'S' suffix variants if different packaging or specific feature subsets are needed. Consider the '64' channel variants if larger screen sizes or higher intersection counts are required for the design.

Touch Screen Controllers Part Context

This component belongs to the PSoC™ Automotive Multitouch Generation 7XL series, designed specifically for high-performance automotive touch interfaces. It integrates programmable system-on-chip technology to handle complex touch processing tasks while maintaining low power consumption and robust noise immunity in electrically noisy vehicle environments.

Touch Screen Controllers Replacement Considerations

Direct substitutes within the same generation include CYAT827AZS59-22002 (different suffix configuration) or CYAT827AZA64-22002 (increased channel count). Verify pinout compatibility and software driver support when transitioning between these variants.
