Infineon Technologies CYAT817AZS72-32002

Overview

CYAT817AZS72-32002 from Infineon is an AEC-Q100 qualified automotive multitouch capacitive touchscreen controller featuring a 32-bit Arm® Cortex® CPU, 72 configurable sense pins, support for up to 10 fingers, and wake-on-touch screen functionality. 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 CYAT817AZS72-32002 datasheet, CYAT817AZS72-32002 pinout, CYAT817AZS72-32002 application, or CYAT817AZS72-32002 equivalent, key selection criteria include its 72-sense-pin TQFP package, absence of force touch/hover/slider features (per ordering table), CAN interface capability, and low-power wake-up button (< 50 µA) for automotive HMI power management.

Technical Context

This device belongs to Infineon's PSoC™ Automotive Multitouch generation 7XL family and implements dual-sense architecture with auto armor EMI suppression. It supports I²C (up to 1 Mbps) and SPI (up to 8 Mbps) as primary host interfaces, plus a configurable secondary I²C/SPI or CAN interface requiring custom firmware.

The controller integrates 64 dedicated RX ADC channels and on-chip DSP for real-time noise filtering, enabling single-pass long-side scanning. Its analog supply range is 3.0–5.5 V, logic supply is 1.71–1.95 V and 3.0–5.5 V, and typical deep sleep power is 30 µW - optimized for always-on automotive touch sensing.

FAQ

Does CYAT817AZS72-32002 support CAN communication out of the box?

No. The CAN interface is implemented as a secondary configurable SCB (Serial Communication Block) that requires custom firmware to enable and configure. Hardware pins (CANH/CANL) are present on the 100LD TQFP package, but default operation uses I²C or SPI as primary host interface.

What is the maximum supported touchscreen size for CYAT817AZS72-32002?

The device supports screen sizes up to 15 inches diagonal, based on its 72 sense pins, 2500 intersection capacity, and 16:10 aspect ratio optimization. Electrode pitch is specified at 5.3 mm, and it accommodates Manhattan, diamond, SOL, and SLIM sensor topologies.

Is hover sensing or force touch enabled on this variant?

No. According to Infineon's official ordering table, CYAT817AZS72-32002 explicitly omits hover, force touch, slider, and CAPSENSE™ button features. These functions are present only in variants ending in -3BFBA, -3B202, or -33002.

What power supply configurations does CYAT817AZS72-32002 require?

It requires two independent supplies: VDDA (3.0–5.5 V) for analog circuitry including ADCs and CAPSENSE™, and VDDIO (1.71–1.95 V or 3.0–5.5 V) for digital I/O and core logic. Deep sleep current is typically 30 µW, and average active power is 30 mW under typical scan conditions.
