CYAT827AZA59-3200A

Touch Screen Controllers Overview

The CYAT827AZA59-3200A is an automotive-grade, multi-touch capacitive touchscreen controller from Infineon's PSoC™ Automotive Generation 7XL family. Designed for hybrid in-cell sensor configurations, it integrates a 32-bit Arm® Cortex® CPU and supports up to ten simultaneous touch points with thin glove tracking. The device features 59 receive channels and operates within a supply voltage range of 1.71 V to 5.5 V. It utilizes I²C communication at 100 or 400 kbps and is housed in a 100-pin TQFP package (14 × 14 × 1.4 mm). Qualified under AEC-Q100 standards, it functions reliably in temperatures ranging from -40°C to +85°C.

Touch Screen Controllers Feature Summary

• Automotive AEC-Q100 qualified with integrated DSP for noise filtering and faster scanning
• Supports hybrid in-cell sensors with AutoArmor technology for electromagnetic emission and immunity improvement
• Enables multitouch functionality with water rejection, large object rejection, and automatic baseline tracking
• Operates on dual power domains: 1.71–1.95 V for logic/digital I/Os and 3.0–5.5 V for analog supplies

Touch Screen Controllers Applications

• Automotive infotainment systems requiring high reliability and noise suppression
• Hybrid in-cell touchscreen displays with screen sizes up to 20 inches diagonal
• Interfaces demanding robust performance in environments with high EMI or display noise

Touch Screen Controllers Procurement Notes

Verify the specific ordering suffix and temperature grade against project requirements before procurement. Confirm availability status directly with Infineon Technologies or authorized distributors, as lifecycle information may vary. Ensure compliance with moisture sensitivity levels and reflow temperature limits during assembly processes.

Touch Screen Controllers Selection Notes

Select this component when designing automotive applications necessitating AEC-Q100 certification and hybrid in-cell sensor compatibility. The 59 RX channel configuration suits displays with aspect ratios around 16:10. Consider the integrated DSP capabilities if system constraints require low average power consumption and high refresh rates up to 250 Hz.

Touch Screen Controllers Part Context

This part belongs to the PSoC™ Automotive Multitouch Generation 7XL series, which targets advanced automotive human-machine interfaces. The 'A' suffix in the model number indicates the Automotive-A temperature range (-40°C to +85°C), distinguishing it from the Automotive-S variant rated up to 105°C. The 'ZA' designation specifies the 100-pin TQFP package type.

Touch Screen Controllers Replacement Considerations

Within the same product line, the CYAT827AZS59-3200A offers identical electrical and functional specifications but supports an extended operating temperature range up to 105°C. Other variants in the table differ by receive channel count or gesture support capabilities.
