CYAT827AZS59-22002

Touch Screen Controllers Overview

The CYAT827AZS59-22002 is an automotive-grade, PSoC-based multitouch capacitive touchscreen controller designed for hybrid in-cell sensor configurations. It integrates a 32-bit Arm Cortex CPU and supports up to 59 receive channels with 16:10 aspect ratio compatibility. The device operates within a supply voltage range of 1.71 V to 5.5 V and functions across an ambient temperature range of -40°C to 105°C (Automotive-S). Key electrical features include effective 20-V drive capability, integrated DSP for data filtering, and I2C communication at 100/400 kbps.

• Features 64 RX channels architecture with individual ADCs per channel

Touch Screen Controllers Applications

• Automotive infotainment systems
• Vehicle instrument clusters
• In-car navigation displays

Touch Screen Controllers Procurement Notes

Verify the specific suffix 'S' indicates the Automotive-S temperature grade (-40°C to 105°C) compared to the 'A' variant. Confirm package availability as the component utilizes a 100-pin TQFP form factor. Ensure compliance with automotive environmental standards during sourcing.

Touch Screen Controllers Selection Notes

Select this model for hybrid in-cell display integration requiring high noise suppression. Choose based on the need for 59 receive channels versus the 64-channel alternative. Consider the 105°C operating limit for under-hood or high-heat cabin environments where standard automotive grades are insufficient.

Touch Screen Controllers Part Context

This component belongs to the Infineon PSoC Automotive Multitouch Generation 7XL family. It is specifically engineered for hybrid in-cell sensor topologies where TX/VCOM share layers and RX ITO sits above the color filter. It serves as a specialized solution for modern vehicle interfaces demanding robust multi-touch performance.

Touch Screen Controllers Replacement Considerations

The CYAT827AZA59-22002 offers identical functionality but is rated for the lower Automotive-A temperature range (-40°C to 85°C). Verify thermal requirements before substituting, as the 'S' suffix denotes the extended high-temperature capability essential for specific automotive zones.
