Product details
Overview
CYAT817AZS88-52002 from Infineon is an AEC-Q100 qualified automotive multitouch capacitive touchscreen controller featuring a 32-bit Arm® Cortex® CPU, 88 configurable sense pins, support for up to 10 fingers, and wake-on-touch screen functionality. It delivers noise-suppression technologies for display and EMI, water rejection, wet-finger tracking, and glove support (up to 1 mm thin glove), targeting infotainment displays in automotive cockpits.
For engineers reviewing the CYAT817AZS88-52002 datasheet, CYAT817AZS88-52002 pinout, CYAT817AZS88-52002 application, or CYAT817AZS88-52002 equivalent, this device is selected for its TQFP-128 package, 1.71–1.95 V/3.0–5.5 V dual-supply operation, 30 mW average power consumption, and I²C/SPI host interface compatibility in safety-critical touch systems.
Technical Context
This PSoC™ Automotive Multitouch generation 7XL controller implements dual-sense architecture for simultaneous water rejection and wet-finger tracking, with configurable TX/RX channel mapping across 88 pins. Its integrated DSP enables single-pass long-side scanning using 64 dedicated RX ADCs and supports high-frequency TX hopping up to 300 kHz for optimal noise filtering.
The device operates in Automotive-A temperature range (–40°C to +85°C) and provides low-power look-for-touch mode (<50 µA wake-up button current). Secondary communication interfaces include configurable I²C/SPI and optional CAN - enabled via custom firmware - supporting functional safety diagnostics and redundant data paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar multitouch controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYAT817AZS88-5BFBA | Includes full feature set: force touch, slider, haptic feedback, acoustic sensing, proximity, and CAN interface | Required for systems needing force-based UI interaction, haptic confirmation, or CAN-based safety messaging | Select when force sensing, haptics, or automotive network integration are mandatory design requirements |
| CYAT817AZS77-52002 | 77 sense pins, same package footprint (128LD TQFP), identical power and interface specs, but reduced sensor count | Suitable for smaller displays (≤12 inch) or cost-optimized designs where 88-pin density is unnecessary | Choose for BOM cost reduction without sacrificing thermal, power, or interface compatibility |
Compared with CYAT817AZS88-5BFBA, this variant omits force/haptic/CAN features to reduce firmware complexity and certification scope; versus CYAT817AZS77-52002, it adds 11 sensor I/Os for larger displays or higher-resolution touch grids while retaining identical power envelope and package.

FAQ
Does CYAT817AZS88-52002 support CAN communication natively?
No. CAN interface capability requires custom firmware activation on the secondary SCB and is not enabled in this variant's factory configuration. The part number suffix "-52002" explicitly denotes absence of CAN, unlike "-5BFBA" variants which ship with CAN firmware preloaded and validated.
What is the maximum electrode pitch supported for reliable 10-finger tracking?
The device supports up to 5.3 mm electrode pitch while maintaining stable 10-finger tracking at 250 Hz refresh rate. This specification is verified with Manhattan-pattern sensors on glass substrates and assumes proper grounding, shielding, and VCCTX supply stability per Infineon's layout guidelines.
Is Android driver support included out-of-the-box?
Yes. Infineon provides a certified Android HAL driver package for CYAT817X devices, including CYAT817AZS88-52002. The driver supports standard Linux input subsystem (evdev), gesture reporting, and power management hooks for suspend/resume cycles in Android Automotive OS.
Can this part be used in Automotive-S temperature grade applications?
No. CYAT817AZS88-52002 is qualified only for Automotive-A grade (–40°C to +85°C). For extended temperature operation up to +105°C, select CYAT817SZS88-52002 (note 'S' in position 6 of part number), which undergoes additional qualification testing and screening.
