Product details
Overview
CYAT817AZA88-5B002 from Infineon is an AEC-Q100 qualified automotive multitouch capacitive touchscreen controller featuring a 32-bit Arm® Cortex® CPU, 88 configurable sense pins (98 total sensor I/Os + 5 TX-only), 10-finger tracking, hover sensing up to 35 mm, and force touch capability (0.1 N resolution, 0.5–10 N range). It supports wet-finger and thin-glove (≤1 mm) operation, operates across –40°C to 85°C, and delivers 30 mW typical active power with <50 µA low-power wake-up button current.
For engineers reviewing the CYAT817AZA88-5B002 datasheet, CYAT817AZA88-5B002 pinout, CYAT817AZA88-5B002 application, or CYAT817AZA88-5B002 equivalent, this device is selected for high-SNR automotive infotainment touchscreens requiring dual-sense water rejection, split-screen support, free-form shape recognition, and CAN-based safety communication interface integration.
Technical Context
This PSoC™ Automotive Multitouch generation 7XL controller implements multi-phase TX (up to 17 phases) with 5 V VCCTX supply enabling effective 20 V drive for enhanced SNR, and integrates 64 dedicated RX channels each with its own ADC for single-pass long-side scanning. Its embedded DSP accelerates noise filtering and touch data processing at up to 250 Hz refresh rate.
The device supports parallel touch/force scan using five RX channels, enables runtime diagnostics and field upgrades via bootloader, and includes optional cryptographic engine for secure host communication. Secondary I2C/SPI and CAN interfaces are available for safety-critical system partitioning, with CAN requiring custom firmware enablement.

IC Role / Device Role / Timing Role: Safety-augmented touch processor using secondary CAN interface to relay validated touch events to MCU domain controller. Use Value: Runtime diagnostics confirm sensor integrity before critical actuation; AEC-Q100 Grade A qualification ensures reliability at 85°C ambient. |
| Head-Up Display (HUD) Control Panel | Center Console Haptic Slider |
Use Scenario: Compact, curved plastic-over-glass touch panel adjacent to HUD projection area, subject to EMI from display drivers. IC Role / Device Role / Timing Role: EMI-resilient touch controller leveraging Auto Armor and high-frequency TX hopping to suppress display-induced noise. Use Value: 300 kHz max TX frequency and multi-phase drive maintain >40 dB SNR despite proximity to high-speed video signals. | Use Scenario: Linear slider zone on center console for climate or media volume control, requiring precise force feedback and gesture continuity. IC Role / Device Role / Timing Role: Force-capable multitouch controller using five parallel RX channels to simultaneously resolve position and pressure on slider electrodes. Use Value: 0.1 N force resolution enables fine-grained haptic response tuning; 100 Hz force refresh rate matches human perception latency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive multitouch controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYAT817AZA88-5B202 | Includes slider and haptic gesture support; same 88-pin configuration and CAN interface | Required when UI demands physical slider emulation or vibration feedback coordination | Select if haptic actuator synchronization and multi-gesture recognition are mandatory |
| CYAT817AZA88-53002 | Enables CAPSENSE™ buttons and force touch; lacks slider/haptic features but retains CAN and water rejection | Suitable for button-dominant HMI with minimal sliding interaction (e.g., HVAC control panel) | Select for cost-optimized button+force implementations where slider functionality is unused |
Compared with CYAT817AZA88-5B202 and CYAT817AZA88-53002, the -5B002 provides identical core sensing capability and CAN safety interface but omits slider/haptic and CAPSENSE™ button features-making it optimal for pure multitouch + force + hover applications with minimal feature overhead.

FAQ
What is the maximum supported touchscreen size for CYAT817AZA88-5B002?
The CYAT817AZA88-5B002 supports screens up to 15-inch diagonal with 16:10 aspect ratio and 5.3 mm electrode pitch. Its 88 configurable sense pins enable up to 2500 intersections, allowing full coverage of large-format displays while maintaining 10-finger tracking and 250 Hz refresh rate under standard configurations.
Does CYAT817AZA88-5B002 support CAN FD or only classical CAN?
CYAT817AZA88-5B002 supports only classical CAN (ISO 11898-1), not CAN FD. The datasheet specifies "CAN interface" without FD capability, and the secondary SCB interface is implemented as standard CAN 2.0B with fixed 1 Mbps arbitration phase timing. No FD bit-rate switching or extended data length features are documented or enabled in firmware.
How does the device handle wet-finger operation without false triggers?
It uses dual-sense capability with independent TX/RX phase analysis to distinguish water films from conductive touch objects. By comparing signal amplitude, phase shift, and decay characteristics across two sensing modes, the controller rejects water droplets while retaining sensitivity to intentional finger contact-even during sustained moisture exposure on the overlay surface.
Is Android driver support included out-of-the-box?
Yes-Infineon provides a certified Android HAL (Hardware Abstraction Layer) driver package for CYAT817X devices, including CYAT817AZA88-5B002. The driver supports standard Linux input subsystem (evdev), multi-touch protocol B, and integrates with Android's GestureService for swipe, pinch, and rotate gestures without vendor-specific middleware.
