Product details
Overview
CYAT827AZS59-2200A from Infineon is an AEC-Q100 qualified automotive-grade in-cell capacitive touchscreen controller featuring a 32-bit Arm® Cortex® CPU, 59 RX channels, 10-finger tracking with ≤1-mm glove support, and integrated DSP for noise-suppressed touch scanning up to 250 Hz - deployed in infotainment displays up to 20-inch diagonal.
For engineers reviewing the CYAT827AZS59-2200A datasheet, CYAT827AZS59-2200A pinout, CYAT827AZS59-2200A application, or CYAT827AZS59-2200A equivalent, key selection criteria include RX channel count (59), automotive temperature range (–40°C to 105°C), I²C interface speed (400 kbps), water/glove rejection capability, and TQFP-100 package compatibility with in-cell sensor stackups.
Technical Context
This device implements a hybrid in-cell architecture where TX/VCOM share the same layer and RX ITO resides above the color filter, enabling high SNR via 20-V effective drive and AutoArmor EMI mitigation. It integrates per-channel ADCs across all 59 RX inputs and uses on-chip DSP to perform single-pass long-side scanning.
The controller supports field upgrades via bootloader, includes touchscreen self-test and manufacturing test kit (MTK), and delivers Android driver support with automatic baseline tracking for environmental drift compensation - all configured through register-level programming without external firmware dependencies.

FAQ
What is the maximum supported display size and aspect ratio?
CYAT827AZS59-2200A supports displays up to 20-inch diagonal with 16:10 aspect ratio and 5.3-mm electrode pitch. Its 59 RX channels and 2176 intersection capacity are optimized for this geometry - exceeding typical 12–17-inch center-stack implementations while maintaining SNR integrity under automotive EMI conditions.
Does this part require external flash for firmware storage?
No. The device integrates on-chip flash memory sufficient for factory-programmed firmware, bootloader, and runtime configuration tables. Field updates are performed in-place via the I²C interface using signed images verified by hardware crypto accelerators - no external memory IC is needed for standard operation.
How is water rejection implemented without user intervention?
Water rejection uses multi-frequency capacitance measurement and adaptive thresholding across all 59 RX channels. The controller autonomously distinguishes water films from finger contact by analyzing phase shift and amplitude decay profiles - no manual mode switching or host-triggered reconfiguration is required during operation.
Is rotary knob support enabled by default in this variant?
Yes. The "S" suffix in CYAT827AZS59-2200A denotes inclusion of rotary knob functionality per ordering code definitions. This is implemented via dedicated sigma-delta modulator inputs and on-chip angle calculation engine - requires no additional external components and operates concurrently with touch sensing.
