CYAT81688-100AS61

Touch Screen Controllers Overview

The CYAT81688-100AS61 is a capacitive touchscreen controller from Infineon Technologies, part of the TrueTouch Standard TS4200 family. It integrates an Arm Cortex-M0 CPU and supports I2C and SPI interfaces. The device operates within a supply voltage range of 1.71 V to 5.5 V and draws approximately 20 mA during operation. It features 61 sensor pins, supporting up to 10 simultaneous touch points. The component is housed in a 100-pin TQFP package and includes four ADC inputs for additional sensing capabilities.

Touch Screen Controllers Feature Summary

• Generates 61 sensor channels with support for thick overlays and gloves
• Integrates gesture recognition and capacitive button functionality
• Includes an Arm Cortex-M0 processor for flexible application logic
• Supports both I2C and SPI communication protocols

Touch Screen Controllers Applications

• Automotive infotainment systems requiring multi-touch input
• Industrial control panels with thick overlay requirements
• Smart home interfaces needing gesture detection

Touch Screen Controllers Procurement Notes

Verify the specific suffix 'S61' against official datasheets to confirm pinout and electrical characteristics, as suffixes often denote packaging or temperature grade variations. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Ensure ordering quantities align with manufacturer minimum order requirements.

Touch Screen Controllers Selection Notes

Select this model when 61 sensor lines are required for large displays or complex button arrays. Compare operating temperature ranges if deployment exceeds standard commercial limits. Verify interface compatibility with the host microcontroller, noting support for both I2C and SPI modes.

Touch Screen Controllers Part Context

This component belongs to the CYAT8168X series, designed for automotive and industrial human-machine interfaces. It succeeds earlier TrueTouch generations by offering enhanced noise immunity and thicker glass tolerance. The series is optimized for high-reliability environments where robust touch performance is critical.
