CYAT847AZS88-42002

Overview

The CYAT847AZS88-42002 is a slave capacitive touchscreen controller from the PSoC Automotive Multitouch Generation 7XL series. It features a 32-bit Arm Cortex CPU and supports screen sizes up to 35 inches with up to 296 sense pins and 10,320 intersections. The device operates on a 3.0 V to 5.5 V analog supply and 1.71 V to 5.5 V logic supply. It provides a refresh rate up to 120 Hz and reports up to ten fingers. The component is housed in a 128-pin TQFP package and meets Automotive-S temperature requirements of -40°C to +105°C.

Feature Summary

• AEC-Q100 qualified multi-chip capacitive touchscreen controller with 32-bit Arm Cortex CPU
• Supports screens up to 35-inch diagonal with up to 296 sense pins and 10,320 intersections
• Includes AutoArmor for EMI noise suppression and DualSense for water rejection and wet-finger tracking
• Reports up to ten fingers with support for thin gloves (≤1 mm) and thick gloves (≤5 mm)

Applications

• Automotive infotainment systems requiring high reliability
• Large display touch interfaces up to 35 inches
• Multi-chip touchscreen architectures

Procurement Notes

Verify the specific ordering code against the official Infineon datasheet to confirm pin count, package type, and temperature range. Ensure compatibility with the host system's I2C interface rates and power supply requirements before procurement.

Selection Notes

Select this model as a slave unit within a multi-chip configuration. Confirm that the required number of sense pins (up to 296) and intersections fits the design. Verify that the 128-pin TQFP package aligns with the PCB layout constraints.

Part Context

This part belongs to the PSoC Automotive Multitouch Generation 7XL family designed for automotive electronics. It complements master controllers in a multi-chip setup to handle large displays. The 'S' suffix indicates an extended temperature range suitable for harsh automotive environments.

Replacement Considerations

Direct replacements must be from the same Generation 7XL family. Check if the application requires a master or slave role, as this is a slave device. Ensure the replacement supports the necessary sense pin count and package size.
