Product details
Overview
CYAT817AZS98-523DA 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 slider, haptic, acoustic, and proximity sensing. It enables robust multitouch operation on up to 15-inch displays with wet-finger, glove (≤1 mm), and fingernail tracking in automotive infotainment and digital cockpit systems.
For engineers reviewing the CYAT817AZS98-523DA datasheet, CYAT817AZS98-523DA pinout, CYAT817AZS98-523DA application, or CYAT817AZS98-523DA equivalent, key selection criteria include its 128LD TQFP package, CAN interface capability, dual-sense water rejection, low-power wake-on-touch (<50 µA), and support for split-screen and free-form shape recognition in safety-critical vehicle HMI designs.
Technical Context
This device implements a generation-7XL PSoC™ Automotive Multitouch architecture with integrated DSP for single-pass long-side scanning across 64 RX channels, each with dedicated ADC. It supports high-frequency TX hopping up to 300 kHz and multi-phase TX drive (17-phase) delivering effective 20 V for enhanced SNR under EMI-heavy automotive environments.
The controller integrates a secondary safety communication interface (I2C/SPI master/slave configurable) and optional CAN physical layer support-requiring custom firmware enablement. Its force touch capability uses five dedicated RX channels with 0.1 N resolution and 100 Hz refresh rate, implemented via rigid-body mechanics without external transducers.

FAQ
Does CYAT817AZS98-523DA support CAN communication out of the box?
No. CAN physical layer support requires custom firmware implementation and is not enabled by default. The device includes CANH/CANL pins and internal PHY circuitry, but the secondary SCB must be configured as CAN master via Infineon-provided middleware and validated against ISO 11898-2. No external transceiver is needed once firmware is deployed.
What is the maximum electrode pitch supported for reliable 10-finger tracking?
The device supports up to 5.3 mm electrode pitch while maintaining full 10-finger tracking accuracy and SNR margin. This is validated with Manhattan and diamond sensor layouts on PET and glass substrates, and applies to both LCD and AMOLED displays with integrated metal mesh layers.
How does the low-power wake-on-touch mode achieve <50 µA current draw?
It uses dedicated hardware state machines that monitor only WAKE# pin transitions and minimal CAPSENSE™ baseline drift - bypassing the Arm® Cortex® core and DSP entirely. Only the analog front-end and comparator logic remain active, with automatic reinitialization upon wake event to preserve full functionality.
Can CYAT817AZS98-523DA drive touch sensors on curved or 3D-shaped displays?
Yes. Its 103-pin configurability supports non-rectangular electrode routing, including free-form shapes and segmented zones. The dual-sense architecture and auto-baseline tracking compensate for mechanical deformation-induced capacitance variation, validated on 3D-formed polycarbonate overlays used in premium automotive applications.
