Product details
Overview
CYAT817AZS61-3A002 from Infineon is an AEC-Q100 qualified automotive-grade capacitive touchscreen controller featuring a 32-bit Arm® Cortex® CPU, support for up to 10-finger multitouch on 61-sense-pin sensor arrays, hover sensing up to 35 mm, force touch capability, and low-power wake-on-touch screen operation (< 50 µA). It delivers 250 Hz refresh rate, 300 kHz TX frequency, and integrated DSP for noise filtering-deployed in infotainment displays and digital instrument clusters.
For engineers reviewing the CYAT817AZS61-3A002 datasheet, CYAT817AZS61-3A002 pinout, CYAT817AZS61-3A002 application, or CYAT817AZS61-3A002 equivalent, this device supports I²C/SPI host interfaces, dual-sense water rejection, glove tracking (≤1 mm), and CAN as secondary safety interface-critical for automotive HMI design validation and EMI-resilient touchscreen integration.
Technical Context
The CYAT817AZS61-3A002 implements a configurable CAPSENSE™ engine with 61 fully programmable TX/RX sense pins, 5 dedicated force-sensing RX channels, and high-order multi-phase TX (17-phase) enabling 20 V effective drive at 5 V VCCTX for enhanced SNR. Its integrated DSP performs real-time baseline tracking, large-object rejection, and wet-finger compensation in single-pass long-side scanning mode.
It operates across –40°C to +85°C (Automotive-A grade), uses 1.71–1.95 V and 3.0–5.5 V dual-supply domains, and supports runtime diagnostics, bootloader-based field upgrades, and Android driver integration-designed for functional safety-aware HMI subsystems requiring ASIL-B alignment via external monitoring.
Key Specifications

| VCCTX | Capacitive TX drive supply | 5 V input enabling 20 V effective multi-phase TX drive-directly improves touch signal margin against display noise. |
| SCL/SDA | I²C host interface | Standard-mode/fast-mode/HS-mode compatible-used for primary touch data reporting and configuration updates. |
| SPI_MOSI/MISO/SCLK/SS | SPI host interface | 8 Mbps capable-supports high-throughput firmware updates and raw sensor data streaming. |
| CAN_TX/CAN_RX | Secondary safety interface | Configurable as CAN slave (custom firmware required)-enables diagnostic messaging and redundancy in ASIL-B architectures. |
Key Features
| Feature | Design Value |
|---|---|
| Hover sensing up to 35 mm | Enables proximity-based UI pre-activation without physical contact-reduces accidental touches and improves driver attention management. |
| Low-power wake-up button (< 50 µA) | Allows persistent capacitive wake detection during system sleep-eliminates need for mechanical buttons while meeting automotive quiescent current targets. |

FAQ
Does CYAT817AZS61-3A002 support CAN interface out-of-the-box?
No. The CAN interface is implemented as a secondary safety communication path but requires custom firmware to enable and configure it as master or slave. Standard operation uses I²C or SPI for primary touch data transfer; CAN must be activated via Infineon-provided configuration tools and validated against vehicle network timing constraints.
What is the maximum supported touchscreen size for this controller?
The CYAT817AZS61-3A002 supports screens up to 15-inch diagonal with a 16:10 aspect ratio and 5.3 mm electrode pitch. This is enabled by its 61 configurable sense pins, integrated DSP, and 250 Hz refresh rate-validated for both LCD and AMOLED stackups using Manhattan or diamond sensor layouts.
How does the device handle water and wet-finger operation?
It uses dual-sense capability and proprietary water rejection algorithms to distinguish between conductive water droplets and intentional finger touches. Wet-finger tracking remains functional without false triggers, and the auto armor technology dynamically adjusts TX frequency hopping to maintain SNR in humid environments per ISO 10605 testing.
Is Android driver support included with this part number?
Yes. Infineon provides a certified Android HAL (Hardware Abstraction Layer) driver compatible with Android 11 and later, including support for multi-touch gestures, force touch reporting, and wake-on-touch events. Integration requires minimal platform-specific adaptation and is documented in the PSoC™ Automotive Multitouch SDK.
