CYAT817AZS72-22002

Touch Screen Controllers Overview

The CYAT817AZS72-22002 is a capacitive touchscreen controller from the PSoC™ Automotive Multitouch Generation 7XL family. It features a 32-bit Arm® Cortex® CPU and supports up to 72 sense pins with ten-finger multitouch reporting. The device operates within an ambient temperature range of –40°C to 85°C (Automotive-A). Electrical specifications include a logic supply of 1.71 V to 1.95 V or 3.0 V to 5.5 V, and an analog supply of 3.0 V to 5.5 V. Communication interfaces include I²C slave at standard bit rates up to 1 Mbps and SPI slave up to 8 Mbps.

Touch Screen Controllers Feature Summary

• AEC-Q100 qualified for automotive electronics applications
• Supports screen sizes up to 15-inch diagonal with 5.3 mm electrode pitch
• Integrated DSP for data processing and high-frequency TX frequency hopping
• Low-power operation with 30 mW average power and 30 μW typical Deep Sleep power

Touch Screen Controllers Applications

• Automotive infotainment systems
• Vehicle instrument clusters
• Center console touch interfaces

Touch Screen Controllers Procurement Notes

Verify that the specific ordering suffix matches the required feature set, as this model lacks force touch and hover sensing capabilities compared to other variants in the CYAT817X series. Confirm package availability and lead times directly with Infineon Technologies or authorized distributors prior to procurement.

Touch Screen Controllers Selection Notes

Select this component when a 72-sense-pin configuration is required for displays up to 15 inches. Ensure the application environment remains within the –40°C to 85°C operating range. Verify that the host system can support the required I²C or SPI communication speeds and that the power supply rails align with the specified 1.71–5.5 V ranges.

Touch Screen Controllers Part Context

This part belongs to the CYAT817X family of PSoC™ Automotive Multitouch controllers. It shares the same 100LD TQFP package and core architecture as variants like CYAT817AZS61-22002 and CYAT817AZA72-3B002, differing primarily in the number of available sense pins and enabled advanced features such as hover or force touch.

Touch Screen Controllers Replacement Considerations

Direct pin-compatible replacements within the same generation include CYAT817AZS61-22002 (61 pins) if fewer sense lines are sufficient, or CYAT817AZA72-3B002 if additional features like hover sensing are needed. Cross-generation replacement requires firmware adaptation.
