Product details
Overview
CYAT817AZA88-53002 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 force touch sensing (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 displays.
For engineers reviewing the CYAT817AZA88-53002 datasheet, CYAT817AZA88-53002 pinout, CYAT817AZA88-53002 application, or CYAT817AZA88-53002 equivalent, key selection criteria include its 88-sense-pin TQFP package, absence of slider/haptic/gesture features, presence of CAN interface and water rejection capability, and compatibility with glove touch (≤1 mm) and hover sensing (up to 35 mm).
Technical Context
This device implements dual-sense architecture for simultaneous wet-finger tracking and noise immunity via Auto Armor technology. Its integrated DSP enables single-pass long-side scanning using 64 dedicated RX ADCs and supports high-order multi-phase TX (17-phase) at 5 V VCCTX for effective 20 V drive and enhanced SNR.
The controller provides two independent communication interfaces: primary I²C/SPI for touch data and secondary configurable I²C/SPI or CAN for safety-critical host coordination. Force sensing uses five dedicated RX channels with 0.1 N resolution and 100 μm/10 N displacement sensitivity, operating at up to 100 Hz.

FAQ
Does CYAT817AZA88-53002 support CAN communication out of the box?
Yes, CYAT817AZA88-53002 includes a dedicated CAN physical layer interface (CANH/CANL pins), but firmware must be loaded to configure it as master or slave. The CAN interface is intended for safety-related diagnostics or redundant host coordination, not primary touch data transport.
What is the maximum electrode pitch supported by this controller?
The CYAT817AZA88-53002 supports up to 5.3 mm electrode pitch, validated for 16:10 aspect ratio touchscreens up to 15 inches diagonal. This pitch enables fine-grained finger localization while maintaining SNR in automotive-grade sensor stackups with metal mesh or ITO layers.
Is hover sensing functional with thick gloves?
No-hover sensing (up to 35 mm) is specified only for bare fingers or thin gloves (≤1 mm). Thick-glove operation (≤5 mm) is supported only for direct touch, not hover, due to dielectric attenuation limiting field penetration depth in the sensor stackup.
How does the "low-power wake-up button" differ from standard wake-on-touch?
The low-power wake-up button consumes <50 µA in Deep Sleep mode and responds to dedicated button press events, whereas wake-on-touch screen monitors full-area capacitance changes at higher current. The button mode enables ultra-low-power standby for specific UI entry points without continuous screen scanning.
