Product details
Overview
CYAT827AZA59-2200A 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 multitouch tracking with ≤1-mm glove support, and integrated DSP for noise-suppressed scanning up to 250 Hz - deployed in infotainment displays for vehicles requiring high SNR and water/glove rejection.
For engineers reviewing the CYAT827AZA59-2200A datasheet, CYAT827AZA59-2200A pinout, CYAT827AZA59-2200A application, or CYAT827AZA59-2200A equivalent, key selection criteria include RX channel count (59), automotive temperature range (−40°C to +85°C), TQFP-100 package, I²C interface speed (up to 400 kbps), and AutoArmor/DisplayArmor EMI mitigation capabilities.
Technical Context
This device implements a hybrid in-cell sensor architecture where TX/VCOM share the same layer and RX ITO resides above the color filter, enabling compact display integration. Its dual-sense architecture supports simultaneous self-capacitance and mutual-capacitance measurement for robust large-object rejection and fingernail tracking.
The embedded DSP performs real-time filtering and baseline adaptation per RX channel, leveraging 64 dedicated ADCs (though configured for 59 active RX inputs) to enable single-pass long-side scanning - reducing scan time and improving immunity to display-related noise and EMI.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RX Channels | 59 - supports high-resolution touch sensing on large-area in-cell panels up to 20-inch diagonal with 5.3-mm electrode pitch. |
| Operating Temp | −40°C to +85°C (Automotive-A grade) - qualified for cabin-mounted infotainment systems without active thermal management. |
| Supply Voltages | 1.71–1.95 V (core), 3.0–5.5 V (I/O & analog) - enables direct interfacing with standard automotive power rails and display subsystems. |
| Touch Reporting | Up to 10 fingers, 5-mm small-finger resolution, 250-Hz refresh rate - ensures responsive gesture recognition in dynamic driving environments. |
| Interface | I²C slave at 100/400 kbps - compatible with common automotive SoC host controllers and supports Android driver integration. |
| Power Consumption | 30 mW average - meets low-power requirements for always-on touch detection in battery-sensitive vehicle subsystems. |
| EMI Mitigation | AutoArmor + DisplayArmor - reduces radiated emissions and improves immunity against display switching noise and RF interference. |
Pinout & Package
Package: 100-pin TQFP (14 × 14 × 1.4 mm, 0.5-mm pitch), RoHS-compliant, lead-free, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO | Digital I/O supply | 3.0–5.5 V input powering GPIOs, I²C interface, and internal logic buffers - must be decoupled locally for EMI robustness. |
| VDDA | Analog supply | 3.0–5.5 V input for ADCs, sensor drivers, and analog front-end - requires separate low-noise regulation and filtering. |
| VDDCORE | Core logic supply | 1.71–1.95 V input for Arm Cortex-M CPU and digital subsystem - sensitive to ripple; demands tight regulation. |
| SCL / SDA | I²C interface | Open-drain bidirectional bus lines supporting 400 kbps operation - require external pull-ups to VDDIO. |
| RESET_N | Active-low reset | Asynchronous hardware reset input - asserted low for ≥10 µs to initialize firmware and sensor calibration state. |
| INT | Interrupt output | Open-drain signal indicating touch event ready - used by host to trigger data read without polling overhead. |
Key Features
| Feature | Design Value |
|---|---|
| Water rejection | Real-time capacitance drift compensation enables reliable operation during condensation or light surface moisture exposure. |
| Glove mode switching | Automatic detection and seamless transition between bare-finger and ≤1-mm glove modes without host intervention. |
| Fingernail tracking | Dual-sense algorithm distinguishes fingernail contact from finger pad via differential capacitance signature - prevents false touches. |
| Large object rejection | Rejects palm or forearm contact >15 mm diameter using centroid dispersion analysis - critical for driver-facing UIs. |
| Field upgrades | Secure bootloader supports authenticated firmware updates over I²C - enables post-deployment feature enhancements and bug fixes. |

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 |
|---|---|---|---|
| CYAT827AZS59-2200A | Same silicon, extended temperature range (−40°C to +105°C) | Required for engine bay or sun-exposed center stack deployments | Select when operating ambient exceeds +85°C or thermal margin is constrained. |
| CYAT827AZA64-2200A | 64 RX channels vs. 59; identical package and firmware compatibility | Supports larger displays (>12-inch diagonal) or finer electrode pitch layouts | Choose for higher-resolution panels where additional RX channels improve SNR or enable wider aspect ratios. |
Compared with CYAT827AZS59-2200A, this part trades thermal headroom for cost and power optimization in cabin-controlled zones; versus CYAT827AZA64-2200A, it offers lower channel count for reduced BOM complexity and calibrated performance on mid-size displays.

FAQ
Is CYAT827AZA59-2200A pin-compatible with other CYAT827X variants?
Yes - all CYAT827X devices use the identical 100-pin TQFP package with functionally mapped pins. RX channel count differences (59 vs. 64) are handled internally; no PCB redesign is needed when migrating between variants, though firmware configuration must match the selected part's channel allocation.
Does CYAT827AZA59-2200A support I²C clock stretching?
Yes - the I²C slave interface supports clock stretching during internal processing (e.g., touch scan completion or data filtering), ensuring reliable communication even under high host bus load. Maximum stretch duration is 1.2 ms, documented in the full datasheet's I²C timing section.
What is the role of AutoArmor technology in this device?
AutoArmor dynamically adjusts drive waveform timing and amplitude to suppress electromagnetic emissions while simultaneously enhancing immunity to display switching noise and external RF interference - verified per CISPR 25 Class 5 and ISO 11452-4 test standards for automotive EMC compliance.
Can CYAT827AZA59-2200A operate without external crystal or oscillator?
Yes - it integrates a factory-trimmed internal RC oscillator sufficient for I²C communication and touch scanning. An external 24 MHz crystal is optional and only required when maximum timing accuracy is needed for synchronized display interface or advanced gesture algorithms.
