CY8C20160-SX2IT

Overview

The CY8C20160-SX2IT is a capacitive touch sensor IC from Infineon Technologies, designed for user interface applications. It operates within a supply voltage range of 2.4V to 5.25V and features an I²C interface for communication. The device provides up to six input channels for detecting touch presence or proximity. Packaged in a 16-pin SOIC format with a width of 3.90mm, it integrates CapSense technology to enable robust interaction without mechanical components.

Feature Summary

• Capacitive touch detection capability for user interfaces
• I²C serial interface for system integration
• Supports up to six independent input channels
• Operates across a wide voltage range

Applications

• Capacitive touch buttons
• User interface panels
• Proximity sensing modules

Procurement Notes

Verify the specific suffix IT against official Infineon documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with the target I²C bus speed and voltage levels before procurement. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a low-pin-count solution for capacitive sensing is required. The I²C interface simplifies connection to microcontrollers. Consider the 16-SOIC package constraints for PCB layout. Verify that the application environment supports the specified operating voltage range.

Part Context

This part belongs to the PSoC family of programmable systems-on-chip. It functions as a dedicated touch controller rather than a general-purpose processor. The series includes variants with different pin counts and package options, all sharing core CapSense technology.

Replacement Considerations

Check for CY8C20160-SX2I if reel packaging is not required. Consult Infineon's obsolescence notices for alternative members of the CY8C201xx series.
