Product details
Overview
CYAT827AZA59-3200A 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 refresh rate-deployed in infotainment displays up to 20-inch diagonal.
For engineers reviewing the CYAT827AZA59-3200A datasheet, CYAT827AZA59-3200A pinout, CYAT827AZA59-3200A application, or CYAT827AZA59-3200A equivalent, key selection criteria include RX channel count (59), automotive temperature range (−40°C to +85°C), I²C slave interface (100/400 kbps), water/glove rejection capability, and TQFP-100 package compatibility with in-cell hybrid sensor stackups.
Technical Context
This device implements a hybrid in-cell architecture where TX/VCOM share the same layer and RX ITO resides on/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 for single-pass long-side scanning and real-time baseline adaptation to environmental drift.
The embedded DSP offloads touch data filtering and gesture classification from the host, supporting Android driver integration and field upgrades via bootloader. Configuration-dependent performance includes 5.3-mm electrode pitch, 16:10 aspect ratio support, and large-object rejection with grip suppression.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RX Channels | 59 - Enables full coverage of mid-size automotive displays (e.g., 10–12 inch) with fine electrode pitch (5.3 mm) and 16:10 aspect ratio. |
| 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) - Supports dual-rail operation with standard automotive power domains. |
| Refresh Rate | Up to 250 Hz - Delivers low-latency touch response for swipe/gesture navigation in safety-critical HMI contexts. |
| Host Interface | I²C slave at 100/400 kbps - Compatible with common automotive SoCs and avoids need for high-speed parallel bus routing. |
| Power Consumption | 30 mW average - Enables thermally constrained placement behind display glass without local heatsinking. |
| Glove Support | ≤1-mm thickness with automatic mode switching - Maintains usability in cold-weather driving conditions without manual UI intervention. |
Pinout & Package
Package: 100-pin TQFP, 14 × 14 × 1.4 mm, 0.5-mm pitch, RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDIO_0–VDDIO_3 | Digital I/O supply rails | Four independent 3.0–5.5 V supplies for I²C, GPIO, and interrupt pins-enables voltage domain isolation from host SoC. |
| VDDA | Analog supply | 3.0–5.5 V dedicated rail for internal ADCs and sensor front-end-critical for SNR stability in noisy automotive environments. |
| SDA / SCL | I²C data/clock | Open-drain, 100/400 kbps compliant-supports standard automotive I²C bus topology with pull-up to VDDIO. |
| INT | Interrupt output | Active-low, open-drain signal indicating touch event ready-reduces host polling overhead and system-level latency. |
| RESET_N | Hardware reset input | Asynchronous active-low reset-ensures deterministic initialization after power-on or brownout recovery. |
| TX[0:15] | Transmit electrode drivers | 16 high-voltage (20 V effective) outputs for in-cell TX line excitation-supports multiplexed scanning across 59 RX channels. |
| RX[0:58] | Receive electrode inputs | 59 differential-capacitance inputs with per-channel 12-bit ADC-enables parallel acquisition and noise-immune single-pass scanning. |
Key Features
| Feature | Design Value |
|---|---|
| In-cell hybrid sensor support | TX/VCOM co-layering + RX-on-CF architecture reduces mechanical stack thickness and eliminates air-gap parasitics for improved optical clarity and SNR. |
| AutoArmor EMI mitigation | Integrated hardware-based emission and immunity enhancement-eliminates need for external ferrites or shielding in display module design. |
| Water and glove rejection | Real-time capacitance compensation algorithms distinguish rain droplets and thin gloves from finger contact-no user-mode switching required. |
| Manufacturing test kit (MTK) | On-chip self-test capability for RX/TX lines, ADC functionality, and sensor integrity-reduces final test time and enables inline production screening. |
| Android driver support | Pre-validated HAL integration with Linux kernel 4.14+ and Android 9.0+-accelerates HMI development and certification cycles. |

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 |
|---|---|---|---|
| CYAT827AZS59-3200A | Same core spec but rated for −40°C to +105°C (Automotive-S grade) | Required for under-hood or near-engine infotainment modules exposed to higher ambient heat | Select when operating junction temperature exceeds 85°C ambient or when extended thermal qualification is mandated by OEM. |
| CYAT827AZA64-3200A | 64 RX channels vs. 59; identical package and feature set | Suitable for larger displays (>12 inch diagonal) requiring finer electrode pitch or higher resolution touch mapping | Choose when scaling to 15–20 inch displays with >16:10 aspect ratio or tighter electrode spacing (e.g., 4.5 mm). |
Compared with CYAT827AZA59-3200A, the S-grade variant extends thermal envelope for under-dash mounting, while the 64-channel version increases spatial resolution for premium display sizes-both retain identical I²C interface, AutoArmor, and Android driver compatibility.

FAQ
What is the maximum supported display size for CYAT827AZA59-3200A?
The device supports screen sizes up to 20-inch diagonal with 16:10 aspect ratio and 5.3-mm electrode pitch. Its 59 RX channels and 250 Hz refresh rate enable responsive touch performance on mid-to-large automotive displays, including 12-inch center consoles and 10.25-inch digital clusters. Physical limits depend on sensor layout and host processing bandwidth-not internal IC constraints.
Does CYAT827AZA59-3200A require external memory for firmware storage?
No. The device integrates on-chip flash memory for bootloader and application firmware, supporting field upgrades without external SPI NOR or EEPROM. The MTK (Manufacturing Test Kit) and Android HAL are preloaded; customer-specific configuration is stored in nonvolatile registers accessible via I²C.
Can CYAT827AZA59-3200A operate with only one power supply rail?
No. It requires two separate supply domains: 1.71–1.95 V for the core logic and 3.0–5.5 V for I/O and analog circuitry (VDDIO and VDDA). These must be independently regulated; sharing rails risks ADC noise coupling, I²C timing violations, or reset instability under load transients.
Is the CYAT827AZA59-3200A pin-compatible with earlier PSoC Automotive touch controllers?
No. It uses a 100-pin TQFP package with unique pin assignments for its 59 RX inputs, 16 TX outputs, and dual-supply I/O structure. Migration from Gen 6 or prior requires PCB redesign and firmware adaptation due to architectural changes in DSP pipeline, AutoArmor implementation, and register map layout.
