Product details
Overview
CYAT827AZS64-3200A from Infineon is an AEC-Q100 qualified automotive-grade in-cell capacitive touchscreen controller with 64 RX channels, 32-bit Arm® Cortex® CPU, and integrated DSP for real-time touch processing. It supports up to 10-finger tracking with thin-glove (≤1 mm) and fingernail input on displays up to 20-inch diagonal, deployed in infotainment control panels.
For engineers reviewing the CYAT827AZS64-3200A datasheet, CYAT827AZS64-3200A pinout, CYAT827AZS64-3200A application, or CYAT827AZS64-3200A equivalent, key selection criteria include RX channel count (64), automotive temperature range (−40°C to 105°C), I²C interface speed (400 kbps), water/glove rejection capability, and in-cell sensor architecture compatibility.
Technical Context
This device implements a hybrid in-cell sensing architecture where TX/VCOM share the same layer and RX ITO resides above the color filter. Its dual-sense scanning engine and per-channel ADC enable single-pass long-side scanning at up to 250 Hz refresh rate.
The embedded 32-bit Arm® Cortex® CPU executes register-configurable firmware with field-upgradable bootloader support, while AutoArmor and DisplayArmor jointly suppress EMI emissions and improve immunity during display integration.

FAQ
What is the maximum supported display size and aspect ratio?
CYAT827AZS64-3200A supports displays up to 20 inches diagonal with native 16:10 aspect ratio. Its 64 RX channels and configurable TX count enable up to 2176 sensing intersections, matching common automotive widescreen formats without interpolation or resolution loss.
Does this part support both I²C and SPI host interfaces?
No - CYAT827AZS64-3200A supports only I²C (100/400 kbps) as its primary host interface. SPI is not implemented; communication relies on SCL/SDA pins with interrupt-driven data reporting via the INT pin.
Is Android driver support included out-of-the-box?
Yes - Infineon provides validated Android HAL and kernel-level drivers for CYAT827AZS64-3200A, including gesture recognition middleware and integration guides for Android 10 through 13, verified on Qualcomm and NXP reference platforms.
How is water rejection implemented at the hardware level?
Water rejection uses dual-frequency excitation and differential capacitance measurement across adjacent RX electrodes. The integrated DSP analyzes phase and amplitude shifts to distinguish conductive water films from intentional touch - no external hardware or calibration is required.
