CYAT81659-100AA48T

Overview

The CYAT81659-100AA48T is a capacitive slider controller from Infineon Technologies, part of the TrueTouch Standard TS3xxx family. It integrates an ARM Cortex-M0 processor for advanced signal processing and gesture recognition. The device supports I2C and SPI interfaces for host communication. It operates within a supply voltage range of 1.71 V to 5.5 V and functions across temperatures from -40°C to +85°C. The component is housed in a TQFP-64 package suitable for surface-mount assembly.

Feature Summary

• Integrated ARM Cortex-M0 processor for flexible firmware customization
• Supports both I2C and SPI communication protocols
• Capacitive sensing technology with high resolution
• Wide operating voltage range from 1.71 V to 5.5 V

Applications

• Capacitive slider controls in home appliances
• Industrial control panels requiring linear input
• Automotive interior lighting and climate adjustment sliders

Procurement Notes

Verify the specific suffix '100AA48T' against official Infineon documentation to confirm pinout and packaging details, as datasheets for the CYAT8165x series often list variants like the TQFP-64 or TQFP-100. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Check for end-of-life notifications or alternative recommendations directly from the manufacturer.

Selection Notes

Select this component when a dedicated capacitive slider interface is required rather than a full touchscreen matrix. Ensure the host system supports either I2C or SPI at the required clock speeds. Verify that the mechanical design accommodates the TQFP-64 footprint if this package variant is confirmed. Consider power consumption requirements relative to the 1.71 V minimum supply voltage.

Part Context

This part belongs to the Infineon TrueTouch Standard TS3xxx series, which combines capacitive touch sensing with embedded processing capabilities. The CYAT81659 model specifically targets slider applications, distinguishing it from multi-touch controllers in the same family. It leverages PSoC technology to allow custom algorithm development for unique user interface needs.

Replacement Considerations

Consult Infineon's official cross-reference tools for direct replacements within the CYAT8165x family. Verify compatibility of firmware and pinouts before substituting with other models such as the CYAT81655 or CYAT81689.
