Product details
Overview
CYAT817AZA98-53002 from Infineon is an AEC-Q100 qualified automotive multitouch capacitive touchscreen controller featuring a 32-bit Arm® Cortex® CPU, 103 configurable sense pins (98 TX/RX + 5 TX-only), 10-finger tracking, and support for force touch, hover sensing up to 35 mm, and wet-finger/glove operation on LCD/AMOLED displays.
For engineers reviewing the CYAT817AZA98-53002 datasheet, CYAT817AZA98-53002 pinout, CYAT817AZA98-53002 application, or CYAT817AZA98-53002 equivalent, this device delivers configurable multi-phase TX drive (up to 300 kHz), integrated DSP for noise filtering, dual-sense water rejection, and CAN interface support for safety-critical automotive HMI systems.
Technical Context
This PSoC™ Automotive Multitouch generation 7XL controller implements register-configurable CAPSENSE™ with dual-sense architecture for simultaneous TX/RX scanning, enabling robust wet-finger tracking and large-object rejection. It supports high-frequency TX hopping and auto armor technology to suppress EMI emissions and improve immunity in vehicle cabin environments.
The device integrates six SCBs (Serial Communication Blocks): five for primary I²C/SPI touch data transfer and one dedicated secondary interface configurable as CAN master/slave-requiring custom firmware-and includes hardware-accelerated cryptographic engine for secure host communication.

Equivalent & Alternatives
The following parts are listed as comparable options for similar multitouch controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYAT817AZA98-5B202 | Includes hover and force touch features; lacks slider and haptic support | Valid for basic 10-finger touch and proximity UI but not for gesture-rich passenger interfaces | Select when cost-sensitive designs require core multitouch without advanced gesture processing |
| CYAT817AZA98-5BFBA | Full feature set: hover, force, slider, haptic, acoustic, proximity, and gesture support | Targeted for premium infotainment with multi-modal interaction (e.g., swipe-to-adjust HVAC) | Choose when full PSoC™ 7XL capability is needed for future-proofed HMI development |
Compared with CYAT817AZA98-5B202, this part omits slider/haptic features but retains force sensing; versus CYAT817AZA98-5BFBA, it trades off gesture complexity for reduced firmware overhead and lower BOM cost in mid-tier automotive displays.

FAQ
Does CYAT817AZA98-53002 support CAN interface out-of-the-box?
No. The CAN interface is implemented via a secondary SCB that requires custom firmware to configure as master or slave. Hardware pins CANH/CANL are present and electrically compatible with standard CAN transceivers, but functional enablement depends on Infineon-provided middleware and application-specific validation.
What is the maximum electrode pitch supported for reliable touch detection?
The device supports up to 5.3 mm electrode pitch with stable 10-finger tracking and SNR performance, validated for 16:10 aspect ratio touchscreens up to 15-inch diagonal. This pitch enables cost-effective sensor stackups using ITO or metal mesh on PET/glass substrates.
Is CYAT817AZA98-53002 compatible with Android Automotive OS?
Yes. Infineon provides certified Android drivers supporting HAL integration for CYAT817X devices, including CYAT817AZA98-53002. The driver supports multi-touch protocol B, force reporting, and suspend/resume handling aligned with Android Automotive power management requirements.
How does the dual-sense capability improve water rejection performance?
Dual-sense measures mutual capacitance simultaneously on two orthogonal axes, allowing the controller to distinguish conductive water films (which affect both axes uniformly) from finger touch (which creates localized asymmetry). This enables real-time rejection without sacrificing sensitivity or requiring external moisture sensors.
