81688-100AS61KAT

Overview

The CYAT81688-100AS61KAT is a capacitive touchscreen controller from Infineon Technologies, part of the TrueTouch Generation 6XL family. It integrates a PSoC-based microcontroller with dedicated touch sensing capabilities. The device supports up to 10 simultaneous fingers and includes gesture recognition features. It operates within a supply voltage range of 1.71 V to 5.5 V and functions at temperatures between -40°C and +105°C. Communication interfaces include I2C and SPI. The component is housed in a 100-pin TQFP package.

Feature Summary

Supports thick overlays and thick gloves for enhanced usability
Integrated gesture recognition functionality
Waterproof design capability
Low power consumption with wake-up button support

Applications

Automotive human-machine interface (HMI) displays
Smart sensing applications requiring robust touch input
General-purpose embedded systems with capacitive touch requirements

Procurement Notes

Verify the specific suffix 'KAT' against official Infineon documentation to confirm tape-and-reel packaging specifications and any unique manufacturing lot codes. Ensure compatibility with existing PCB footprints for the 100-pin TQFP package before procurement.

Selection Notes

Select this model when automotive-grade reliability (-40°C to +105°C) and support for thick dielectric overlays are required. Compare channel count and pin configuration against similar models like the CYAT81689 if fewer pins are sufficient for the application design.

Part Context

This component belongs to the CYAT8168X series, which represents Generation 6XL of Infineon's TrueTouch technology. It is designed for high-performance multitouch applications, offering improved noise immunity and faster response times compared to previous generations.

Replacement Considerations

Direct replacements may include other variants within the CYAT8168X family, such as CYAT81688-100AS61ZT, provided pinout and electrical characteristics match. Verify package type and operating temperature range for equivalence.
