CYAT827AZA64-3200A

Touch Screen Controllers Overview

The CYAT827AZA64-3200A is an automotive-grade, multi-touch capacitive touchscreen controller from Infineon's PSoC™ Automotive Generation 7XL family. 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 1.71–1.95 V digital/logic supplies and 3.0–5.5 V analog/logic supplies, consuming approximately 30 mW average power. It includes integrated DSP for data processing, AutoArmor for EMI management, and AEC-Q100 qualification.

Touch Screen Controllers Feature Summary

• Automotive AEC-Q100 qualified with -40°C to 85°C (Grade A) or -40°C to 105°C (Grade S) temperature ranges
• Supports up to 64 RX channels, 2176 intersections, and reports up to ten simultaneous touch points
• Integrated DSP and single-pass long-side scanning for faster processing and lower noise
• Advanced gesture and environmental handling including water rejection, thin glove support, and large object rejection

Touch Screen Controllers Applications

• Automotive in-cell hybrid touchscreen displays
• Multi-touch interfaces requiring high noise immunity and EMI suppression
• Touchscreen controllers supporting up to 20-inch diagonal screens

Touch Screen Controllers Procurement Notes

Verify the specific suffix code against the manufacturer's ordering information table to confirm channel count and feature set. Confirm the required ambient temperature grade (A or S) matches the application environment. Ensure the host system supports the I2C slave interface at 100 or 400 kbps for primary communication.

Touch Screen Controllers Selection Notes

Select this component for applications requiring hybrid in-cell sensor configurations where TX/VCOM share a layer. Choose based on the necessary number of receive channels; this model provides 64 RX channels. Consider the 30-mW average power consumption for battery-sensitive automotive systems. Verify compatibility with Android driver support if applicable.

Touch Screen Controllers Part Context

This part belongs to the PSoC™ Automotive Multitouch Generation 7XL Hybrid In-cell series. It shares the 100-pin TQFP package and core ARM Cortex CPU architecture with other variants in the CYAT827X family, differing primarily in the number of receive channels and specific feature sets enabled by the ordering suffix.

Touch Screen Controllers Replacement Considerations

Direct replacements within the same family include CYAT827AZS64-3200A (same specs, different temperature grade), CYAT827AZA59-3200A (59 RX channels), and CYAT827AZS59-3200A (59 RX channels, different temp grade). Ensure the substitute meets the specific channel count and temperature requirements.
