CYAT827AZS59-3200A

Touch Screen Controllers Overview

The CYAT827AZS59-3200A is an automotive-grade, PSoC-based multitouch capacitive touchscreen controller designed for hybrid in-cell sensor configurations. It integrates a 32-bit Arm Cortex CPU and supports up to 59 receive channels with 16:10 aspect ratio compatibility. The device operates within a supply voltage range of 1.71 V to 5.5 V and functions across an ambient temperature range of -40°C to 105°C. Communication is handled via an I2C slave interface supporting 100 and 400 kbps speeds. Key electrical parameters include a maximum power consumption of 30 mW and support for screen sizes up to 20 inches diagonal.

Touch Screen Controllers Feature Summary

• Automotive AEC-Q100 qualified with integrated DSP for faster scanning and noise filtering
• Supports multi-touch gestures, water rejection, and thin glove tracking (≤1 mm)
• Features AutoArmor technology to improve electromagnetic emissions and immunity
• Includes field upgrades via bootloader and manufacturing test kit (MTK) support

Touch Screen Controllers Applications

• Automotive infotainment systems requiring hybrid in-cell touchscreens
• Vehicle displays up to 20-inch diagonal with 16:10 aspect ratios
• Touch interfaces demanding high reliability under varying environmental conditions

Touch Screen Controllers Procurement Notes

Verify the specific ordering suffix 'S' against the datasheet table to confirm the -40°C to 105°C automotive grade designation. Confirm that the 59 RX channel configuration matches the system design requirements. Ensure the host system provides the necessary 1.71–5.5 V logic supply and 3.0–5.5 V analog supply rails as specified in the power section.

Touch Screen Controllers Selection Notes

Select this component when a hybrid in-cell sensor architecture is required for automotive applications. The 59-channel count limits the maximum electrode intersections compared to the 64-channel variants. Verify that the application requires the extended -40°C to 105°C operating temperature range associated with the 'S' suffix rather than the standard automotive grade.

Touch Screen Controllers Part Context

This part belongs to the Infineon PSoC Automotive Multitouch Generation 7XL family. It is specifically engineered for hybrid in-cell display technologies where TX/VCOM share a layer and the RX ITO layer is positioned on or above the color filter. The device replaces older generations by offering higher SNR through effective 20-V drive capabilities.

Touch Screen Controllers Replacement Considerations

The CYAT827AZA59-3200A serves as the standard automotive grade (-40°C to 85°C) equivalent within the same package and feature set. For designs requiring higher channel counts, the 64-channel variants such as CYAT827AZS64-3200A are compatible alternatives.
