Product details
Overview
CYAT817AZA98-5BFBA from Infineon is an AEC-Q100 qualified automotive-grade capacitive multitouch 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 (0.5–10 N), and wet-finger/water-rejection capability for in-vehicle infotainment displays.
For engineers reviewing the CYAT817AZA98-5BFBA datasheet, CYAT817AZA98-5BFBA pinout, CYAT817AZA98-5BFBA application, or CYAT817AZA98-5BFBA equivalent, key selection criteria include its 128LD TQFP package, CAN interface support, dual-sense architecture for water rejection, 250 Hz refresh rate, and low-power wake-on-touch (<50 µA) for automotive human-machine interface (HMI) systems.
Technical Context
This device implements a multi-phase TX architecture with up to 17 phases and 5 V VCCTX supply, delivering effective 20 V drive for enhanced SNR. Its integrated DSP enables single-pass long-side scanning across 64 dedicated RX ADC channels, supporting real-time noise filtering via high-frequency TX hopping.
The controller supports split-screen and free-form shape recognition using CAPSENSE™ technology, with runtime diagnostics, field-upgradable firmware via bootloader, and secondary I2C/SPI safety interface-configurable as master or slave with custom firmware. It includes hardware-accelerated gesture detection and haptic feedback coordination.

FAQ
Does CYAT817AZA98-5BFBA support Android OS integration?
Yes, it includes official Android driver support validated by Infineon for seamless integration into Android-based automotive infotainment platforms. The driver handles touch report formatting, gesture mapping, and power-state transitions-including deep-sleep wake-on-touch synchronization with Android's input subsystem.
What is the role of the 5 TX-only pins in the 103-pin configuration?
These five dedicated TX-only pins enable asymmetric sensor layouts and extended multi-phase TX drive schemes, increasing effective SNR without consuming RX channel resources. They are used in conjunction with the 98 configurable TX/RX pins to support complex electrode topologies like SLIM or hybrid in-cell stackups.
How does the dual-sense capability enable water rejection?
Dual-sense operates self- and mutual-capacitance measurements simultaneously: water films primarily affect self-capacitance, while finger touch dominates mutual-capacitance. By comparing both signals in real time, the IC distinguishes wet-finger input from false triggers caused by condensation or splashes.
Is CAN interface functionality enabled by default in CYAT817AZA98-5BFBA?
No-CAN is implemented as a secondary safety communication interface requiring custom firmware to configure the SCB peripheral as CAN controller. The hardware block is present and AEC-Q100 qualified, but initialization, bit-timing, and protocol stack must be implemented in application firmware.
