Infineon Technologies CYAT817AZS98-42002

Overview

CYAT817AZS98-42002 from Infineon is an AEC-Q100 qualified automotive-grade 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 wet-finger, glove (≤5 mm), and fingernail touch on up to 15-inch displays. It operates across –40°C to 85°C and delivers 250 Hz refresh rate with multi-phase TX drive up to 300 kHz.

For engineers reviewing the CYAT817AZS98-42002 datasheet, CYAT817AZS98-42002 pinout, CYAT817AZS98-42002 application, or CYAT817AZS98-42002 equivalent, key selection criteria include its TQFP-128 package, CAN interface capability, absence of hover/force/slider/CAPSENSE™ button features per ordering code, and reliance on primary I²C/SPI host communication without secondary safety interface firmware enablement.

Technical Context

This device belongs to Infineon's PSoC™ Automotive Multitouch generation 7XL family and implements dual-sense architecture for water rejection and wet-finger tracking. Its 64 dedicated RX ADC channels enable single-pass long-side scanning, while integrated DSP accelerates noise filtering and touch data processing.

The part supports split-screen operation and free-form shape recognition using configurable electrode mapping. It includes runtime diagnostics, bootloader-based field upgrades, and manufacturing test kit (MTK) integration - all validated under Automotive-A temperature grade (–40°C to 85°C).

FAQ

Does CYAT817AZS98-42002 support CAN communication?

No. Although the generation 7XL platform supports optional CAN via secondary SCB firmware, the -42002 ordering code explicitly omits this feature. The device provides only primary I²C and SPI host interfaces, with no CAN transceiver or protocol stack enabled in factory configuration.

What is the maximum supported touchscreen size and resolution?

The controller supports screens up to 15-inch diagonal with up to 2500 electrode intersections. Resolution is determined by electrode pitch (minimum 5.3 mm) and aspect ratio (16:10 supported), enabling native HD (1280×800) or FHD (1920×1080) touch mapping depending on sensor layout and host processing.

Is Android driver support included out-of-the-box?

Yes. Infineon provides certified Android HAL drivers and integration packages for Android 10 through 13, including touch coordinate translation, gesture parsing, and power management hooks - verified with common SoCs like Qualcomm Snapdragon and MediaTek Dimensity platforms.

Can CYAT817AZS98-42002 operate with wet or gloved fingers?

Yes. It implements dual-sense capability and Auto Armor technology to reject water interference and track wet fingers reliably. It also supports two-finger operation with gloves up to 5 mm thick, using adaptive baseline tracking and SNR-optimized multi-phase TX drive.
