Product details
Overview
CYAT827AZS59-22002 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 filtering. It operates across -40°C to 105°C and delivers up to 250 Hz refresh rate for 20-inch displays in infotainment and digital cockpit systems.
For engineers reviewing the CYAT827AZS59-22002 datasheet, CYAT827AZS59-22002 pinout, CYAT827AZS59-22002 application, or CYAT827AZS59-22002 equivalent, key selection criteria include RX channel count (59), automotive temperature grade (AEC-Q100 S-grade), in-cell sensor compatibility, I²C interface speed (400 kbps), and water/glove rejection capability.
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. Its dual-sense scanning and AutoArmor EMI mitigation enable robust operation in high-noise automotive environments.
The integrated 64-channel-capable ADC array (configured for 59 active RX) supports single-pass long-side scanning, while the on-chip DSP accelerates touch data processing and baseline adaptation to environmental drift without host intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar in-cell touchscreen controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYAT827AZA59-22002 | Same silicon, Automotive-A grade (-40°C to +85°C) | Targeted for non-critical cabin zones (e.g., rear seat displays) | Select when full S-grade thermal range is not required and cost optimization is prioritized |
| CYAT827AZS64-22002 | 64 RX channels, identical S-grade temp range and features | Supports larger displays (up to 20-inch diagonal) with higher intersection density | Choose for 16:10 panels exceeding 17-inch diagonal or requiring >59 RX nodes |
Compared with CYAT827AZA59-22002, this part adds extended temperature resilience for front-panel mounting; versus CYAT827AZS64-22002, it trades 5 RX channels for tighter BOM cost and lower routing complexity in mid-size displays.

FAQ
What is the maximum supported display size and aspect ratio?
CYAT827AZS59-22002 supports displays up to 20 inches diagonal with native 16:10 aspect ratio. Its 59 RX channels and 16:10 configuration accommodate electrode pitches down to 5.3 mm, enabling high-resolution touch sensing on wide-format automotive displays without interpolation artifacts.
Does this part require external memory for firmware storage?
No. The device integrates on-chip flash memory for firmware and configuration data, including factory-calibrated parameters and bootloader code. Field upgrades are performed via I²C using the secure bootloader-no external SPI Flash or EEPROM is needed for standard operation.
How does water rejection work without additional sensors?
Water rejection is implemented algorithmically using mutual capacitance delta analysis across multiple frames and frequency hopping. The integrated DSP identifies characteristic water-bead signatures-such as slow capacitance ramping and spatially diffuse coupling-and suppresses false touches without auxiliary moisture sensors or hardware modifications.
Is Android driver support provided out-of-the-box?
Yes. Infineon provides a certified Android HAL (Hardware Abstraction Layer) driver compatible with Android 9–13, including kernel modules, input event mapping, and gesture engine integration. The driver supports standard Android Input Framework APIs and has been validated on Qualcomm Snapdragon Automotive platforms.
