Product details
Overview
CYAT817AZS72-3B002 from Infineon is an AEC-Q100 qualified automotive-grade capacitive touchscreen controller featuring a 32-bit Arm® Cortex® CPU, 72 configurable sense pins, support for 10-finger multitouch, hover sensing up to 35 mm, and force touch capability (0.5–10 N range). It delivers 250 Hz refresh rate, 300 kHz TX frequency, and operates across –40°C to 85°C for in-vehicle infotainment and digital cockpit displays.
For engineers reviewing the CYAT817AZS72-3B002 datasheet, CYAT817AZS72-3B002 pinout, CYAT817AZS72-3B002 application, or CYAT817AZS72-3B002 equivalent, key selection criteria include its TQFP-100 package, dual-sense water rejection, glove support (≤1 mm), low-power wake-on-touch (<50 µA), and CAN interface readiness via secondary SCB configuration.
Technical Context
This device implements a register-configurable CAPSENSE™ architecture with integrated DSP for real-time noise filtering, multi-phase TX (up to 17 phases) enabling 20 V effective drive, and parallel touch/force scan using five dedicated RX channels. Its auto armor technology dynamically adjusts EMI immunity and emissions during operation.
The controller supports split-screen and free-form shape recognition via firmware-defined electrode mapping, and uses dual-sense capability for simultaneous wet-finger tracking and water rejection-critical for automotive HMI under variable environmental conditions.

IC Role / Device Role / Timing Role: Multitouch coordinator supporting split-screen content and free-form gesture recognition. Use Value: Wet-finger tracking allows operation with damp fingers; large object rejection prevents false triggers from arm rests or clothing. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive touchscreen controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYAT817AZS72-3B202 | Includes slider sensing and CAPSENSE™ button support; lacks force touch and hover | Targeted at cost-optimized infotainment panels without haptic or pressure-sensitive UI | Select when force/hover features are unnecessary and slider-based navigation suffices |
| CYAT817AZS72-3BFBA | Enables full feature set: slider, haptics, acoustic feedback, proximity, and CAN interface | Designed for premium cockpits requiring multimodal interaction (touch + force + audio + CAN telemetry) | Choose for systems needing synchronized CAN bus reporting of touch events and force metrics |
Compared with CYAT817AZS72-3B202, this part adds force touch and hover but omits slider/haptic features; versus CYAT817AZS72-3BFBA, it excludes CAN and acoustic feedback-making it optimal for mid-tier automotive HMIs prioritizing core multitouch reliability and glove/water robustness.

FAQ
Does CYAT817AZS72-3B002 support CAN communication natively?
No. CAN is not implemented in hardware; it requires custom firmware to configure the secondary SCB interface as CAN master/slave. The device includes I²C and SPI as native primary interfaces, with CAN functionality dependent on software implementation and external transceiver.
What is the maximum electrode pitch supported for reliable 10-finger tracking?
The device supports up to 5.3 mm electrode pitch while maintaining 10-finger resolution and 250 Hz refresh rate. This specification is validated for 15-inch diagonal displays with 16:10 aspect ratio and standard Manhattan or diamond sensor layouts.
How does the low-power wake-on-touch mode achieve 30 µW consumption?
It uses dedicated ultra-low-power analog comparators and clock-gated digital logic that monitor only essential RX channels in Deep Sleep. Full CPU and ADC arrays remain powered down until a valid touch threshold is crossed on configured wake buttons or screen zones.
Is CYAT817AZS72-3B002 compatible with plastic (PET) and glass sensor substrates?
Yes. The device supports PET and glass substrates, as well as metal mesh, SOL (sensor-on-lens), on-cell, hybrid in-cell, and SLIM (single-layer independent multitouch) architectures-validated across all listed stackups in Infineon's automotive design guidelines.
