Product details
Overview
CYAT817AZS98-5BFFE 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, hover sensing up to 35 mm, force touch (0.1 N resolution), and integrated CAN interface for safety-critical vehicle HMI systems.
For engineers reviewing the CYAT817AZS98-5BFFE datasheet, CYAT817AZS98-5BFFE pinout, CYAT817AZS98-5BFFE application, or CYAT817AZS98-5BFFE equivalent, this device supports split-screen operation, wet-finger and glove-touch (≤5 mm), dual-sense water rejection, auto armor EMI mitigation, and Android driver integration - all in a 128LD TQFP package rated for –40°C to 105°C.
Technical Context
The CYAT817AZS98-5BFFE implements a multi-phase TX architecture with up to 17 phases and 300 kHz TX frequency hopping to suppress display noise and EMI. Its 64 dedicated RX channels each include an independent ADC, enabling single-pass long-side scanning at up to 250 Hz refresh rate.
It integrates dual communication interfaces: primary I²C/SPI for touch data and secondary configurable I²C/SPI or CAN for safety-critical host coordination. Force sensing uses five parallel RX channels with 100 μm/10 N displacement sensitivity and 100 Hz scan rate, supporting rigid-body mechanical implementations.

Use Scenario: Multi-zone seat control panel with slider, buttons, and gesture zones in rear-seat entertainment system. IC Role / Device Role / Timing Role: CAPSENSE™ button and slider processor with runtime diagnostics and manufacturing test kit (MTK) support. Use Value: Slider sensing with free-form shape support enables intuitive volume/brightness control; MTK reduces factory calibration overhead by >40%. | Use Scenario: Transparent touch layer on HUD combiner glass requiring high SNR under direct sunlight and thermal cycling. IC Role / Device Role / Timing Role: High-voltage (20 V effective) TX driver with 300 kHz frequency hopping to overcome solar-cell EMI and temperature-induced baseline drift. Use Value: 20 V effective drive improves SNR by 12 dB over 5 V alternatives; automatic baseline tracking maintains accuracy across –40°C to 105°C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive multitouch controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CYAT817AZS98-5BFBA | Lacks haptic feedback and acoustic gesture support; same 103-pin count and CAN interface | No haptic actuator control or proximity-triggered acoustic response capability | Select when haptics/acoustics are not required and cost optimization is prioritized |
| CYAT817AZA98-5BFBA | Same feature set but Automotive-A grade (–40°C to 85°C) instead of Automotive-S | Not qualified for under-hood or high-ambient cabin locations exceeding 85°C | Select only for non-extreme thermal environments where full Automotive-S qualification is unnecessary |
Compared with CYAT817AZS98-5BFBA and CYAT817AZA98-5BFBA, the CYAT817AZS98-5BFFE uniquely delivers full haptic/acoustic gesture support plus Automotive-S temperature qualification - critical for next-gen EV cockpits requiring simultaneous force, hover, and safety-critical CAN coordination.

FAQ
Does CYAT817AZS98-5BFFE support Android natively?
Yes - Infineon provides certified Android drivers compatible with Android 11 through 14, including HAL integration for gesture mapping, force threshold calibration, and wake-on-touch suspend/resume handling. Driver source code and integration guides are available via MyICP after registration.
What is the maximum supported touchscreen size?
The CYAT817AZS98-5BFFE supports screen sizes up to 15-inch diagonal with 16:10 aspect ratio and 5.3 mm electrode pitch. This is enabled by its 103 sense pins, 64-channel parallel RX architecture, and single-pass long-side scanning capability.
How does the CAN interface function in safety-critical applications?
The CAN interface operates as a secondary SCB configured per Infineon's safety firmware, transmitting validated touch status, diagnostic flags, and force-event timestamps to domain controllers. It complies with ISO 11898-1 and supports error frame detection and bus-off recovery per ASIL-B requirements.
Is external memory required for field firmware updates?
No - the device integrates secure internal flash memory sufficient for dual-bank OTA updates. The bootloader supports encrypted image verification using AES-128 and ECDSA signature checking, eliminating need for external SPI NOR or NAND storage.
