CYAT847AZS72-22002

Overview

The CYAT847AZS72-22002 is a PSoC™ Automotive Multitouch Generation 7XL slave controller designed for multi-chip capacitive touchscreen applications. It features a 32-bit Arm® Cortex® CPU and supports up to 72 sense I/Os with a 100-pin TQFP package (14 × 14 × 1.4 mm). The device operates on a 3.0 to 5.5 V analog supply and 1.71 to 5.5 V logic supply, functioning within an automotive-grade temperature range of -40°C to 105°C. It utilizes an I²C interface at rates up to 1 Mbps.

Feature Summary

• AEC-Q100 qualified for automotive electronics
• Supports thin gloves (≤1-mm) and thick gloves (≤5-mm)
• Integrated AutoArmor and DualSense technologies for noise suppression and water rejection
• Reports up to ten fingers with refresh rates up to 120 Hz

Applications

• Automotive touchscreen displays
• Trackpad interfaces
• Slider controls

Procurement Notes

Verify the ordering suffix 'S' indicates the -40°C to 105°C temperature range and 'T' packaging status if applicable. Confirm the specific number of sense pins required for the target sensor configuration against the 72-pin variant specifications before procurement.

Selection Notes

Select this model as a slave unit in a multi-chip architecture due to the '4' designation in the part number. Ensure the host system requires the extended automotive temperature range (-40°C to 105°C) provided by the 'S' suffix rather than the standard automotive range.

Part Context

This component belongs to the Infineon PSoC™ Automotive Multitouch Generation 7XL family. It is specifically engineered as a slave controller to expand touch sensing capabilities beyond single-chip limits, supporting screen sizes up to 35 inches diagonal with high electrode counts.

Replacement Considerations

Direct replacements within the same generation include CYAT847AZA72-22002 (standard temp) or other 72-pin variants like CYAT847AZS61-22002 if fewer sense pins are sufficient. Cross-generation compatibility requires verification of register configurations.
