Product details
Overview
CYAT827AZA59-22002 from Infineon Technologies 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 CYAT827AZA59-22002 datasheet, CYAT827AZA59-22002 pinout, CYAT827AZA59-22002 application, or CYAT827AZA59-22002 equivalent, key selection criteria include RX channel count (59), automotive temperature range (−40°C to +85°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. Its register-configurable firmware supports field upgrades via bootloader and integrates CAPSENSE® buttons with large-object rejection logic.
The on-chip DSP performs per-channel ADC conversion across all 59 RX inputs in single-pass long-side scanning mode, reducing scan time and improving noise immunity. System-level timing includes configurable refresh rates (up to 250 Hz) and automatic baseline tracking for environmental drift compensation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar in-cell multitouch controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYAT827AZS59-22002 | Same core silicon, extended temp range (−40°C to +105°C) | Required for engine bay-mounted or rear-seat HVAC-integrated displays | Select when operating near heat sources exceeding 85°C ambient |
| CYAT827AZA64-22002 | 64 RX channels, identical package and temp grade | Supports wider aspect ratios (e.g., 21:9 cinema displays) and higher electrode density | Select when screen diagonal exceeds 18 inches or electrode pitch <5.0 mm |
Compared with CYAT827AZS59-22002, this part trades extended temperature margin for lower cost and qualification scope; compared with CYAT827AZA64-22002, it reduces channel count to optimize BOM cost and power for mid-tier 12–17-inch displays without sacrificing glove/water performance.

FAQ
What is the maximum supported display size and resolution for CYAT827AZA59-22002?
This controller supports displays up to 20-inch diagonal with 16:10 aspect ratio and 5.3-mm electrode pitch. It handles up to 2176 sense intersections across 59 RX channels, enabling native resolution support for 1920×1200 panels when paired with appropriate TX channel count and host processing bandwidth.
Does CYAT827AZA59-22002 require external memory or firmware storage?
No - the device integrates flash memory for firmware storage and includes a secure bootloader for field updates. All configuration registers, calibration data, and gesture algorithms reside on-chip; no external EEPROM or SPI flash is required for basic operation or manufacturing test kit (MTK) deployment.
How does the water rejection feature operate without user intervention?
Water rejection uses real-time capacitance variance analysis across adjacent electrodes combined with temporal filtering in the integrated DSP. When liquid bridges multiple nodes, the algorithm suppresses false touches while preserving intentional input - no manual mode switch or host software involvement is needed.
Is CYAT827AZA59-22002 pin-compatible with prior-generation CYAT825 devices?
No - CYAT827AZA59-22002 uses a 100-pin TQFP package with different power domain partitioning, I/O voltage ranges, and interrupt signaling behavior. Migration requires PCB layout revision, updated power sequencing, and firmware adaptation due to architectural changes in the Cortex-M core and CAPSENSE® engine.
