CYAT827AZS64-2200A

Touch Screen Controllers Overview

The CYAT827AZS64-2200A is an automotive-grade, PSoC-based multitouch capacitive touchscreen controller from Infineon Technologies. It features a 32-bit Arm Cortex CPU and supports up to 64 RX channels with 2176 intersections for screens up to 20 inches. The device operates on a 1.71–1.95 V digital supply and 3.0–5.5 V analog/logic supply, consuming approximately 30 mW average power. It communicates via I2C at 100 or 400 kbps. Qualified under AEC-Q100, it functions in temperatures from -40°C to 105°C (Automotive-S) within a 100-pin TQFP package.

Touch Screen Controllers Feature Summary

• AEC-Q100 qualified with Automotive-S temperature rating (-40°C to 105°C)
• Supports 64 RX channels, 2176 intersections, and reports up to ten fingers
• Integrated DSP and AutoArmor technology for noise suppression and EMI immunity
• Features water rejection, thin glove support (≤1 mm), and fingernail tracking

Touch Screen Controllers Applications

• Automotive infotainment systems
• In-cell hybrid touchscreen sensor integration
• Multi-touch user interfaces requiring high SNR and low power

Touch Screen Controllers Procurement Notes

Verify the specific suffix 'S' indicates the extended temperature range of -40°C to 105°C compared to the 'A' variant. Confirm availability through official Infineon channels as lifecycle status may vary. Ensure the ordering code matches the required 64 RX channel configuration and 100-TQFP package type.

Touch Screen Controllers Selection Notes

Select this model for applications requiring 64 receive channels and support for large displays up to 20 inches diagonal. Choose the 'S' suffix version when operation above 85°C ambient temperature is required. Ensure the host system supports I2C communication and provides the necessary dual voltage supplies (1.71–1.95 V and 3.0–5.5 V).

Touch Screen Controllers Part Context

This component belongs to the PSoC Automotive Multitouch Generation 7XL series. It is designed specifically for hybrid in-cell sensor configurations where TX/VCOM share a layer and the RX ITO layer is positioned on or above the color filter. It replaces previous generations with enhanced noise filtering and higher channel counts.

Touch Screen Controllers Replacement Considerations

The CYAT827AZA64-2200A is a compatible alternative with identical electrical and functional specifications but limited to an operating temperature range of -40°C to 85°C. Verify thermal requirements before substituting.
