CYAT827AZS64-3200A

Overview

The CYAT827AZS64-3200A is a PSoC™ Automotive Multitouch Generation 7XL Hybrid In-cell 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 diagonal. The device operates on a 3.0 V to 5.5 V analog supply and 1.71 V to 5.5 V logic supply, consuming approximately 30 mW average power. It includes an integrated DSP, AutoArmor noise suppression, and I²C communication at 100/400 kbps. Available in a 100-pin TQFP package, it meets AEC-Q100 standards for automotive applications.

Feature Summary

• Automotive-grade AEC-Q100 qualification with -40°C to +105°C (Automotive-S) operating temperature range
• Hybrid In-cell sensor support with 64 RX channels and integrated DSP for fast scanning
• Advanced touch capabilities including water rejection, large object rejection, and nail tracking
• Low power consumption of 30 mW average with configurable refresh rates up to 250 Hz

Applications

• Automotive infotainment systems requiring high reliability
• In-cell hybrid display integration for driver and passenger interfaces
• Multi-touch control panels supporting glove and wet finger operation

Procurement Notes

Verify the specific suffix '3200A' indicates the inclusion of gesture and rotary knob support compared to standard variants. Confirm the 'S' designation ensures the extended -40°C to +105°C temperature rating required for harsh automotive environments. Check current availability status directly with Infineon or authorized distributors as lead times may vary.

Selection Notes

Select this model for applications requiring 64 receive channels and hybrid in-cell sensor compatibility. Ensure the host system supports I²C communication at 100 or 400 kbps. Verify that the power supply rails can provide 3.0–5.5 V for analog circuits and 1.71–5.5 V for digital logic. Consider the 100-pin TQFP footprint for PCB layout constraints.

Part Context

This component belongs to the PSoC™ Automotive Multitouch Generation 7XL series, designed specifically for automotive electronics. It builds upon previous generations by adding gesture recognition and rotary knob support (indicated by the 3200A suffix). The series emphasizes noise immunity through DisplayArmor and AutoArmor technologies for use in electric vehicles.

Replacement Considerations

The CYAT827AZS64-2200A is a compatible alternative within the same family but lacks the gesture and rotary knob support features found in the 3200A variant. Both share the same 64-channel configuration and 100-TQFP package.
