CY8CMBR3116-LQXIT

Overview

The CY8CMBR3116-LQXIT is a CapSense Express controller supporting up to 16 capacitive sensing inputs, including buttons and proximity sensors. It operates within a voltage range of 1.71 V to 5.5 V and functions across an industrial temperature range of –40 °C to +85 °C. The device features SmartSense Auto-tuning for continuous performance compensation and liquid tolerance to prevent false touches. It communicates via an I2C interface supporting up to 400 kHz and includes system diagnostics for fault detection.

Feature Summary

Register-configurable CapSense Express controller eliminating firmware development
SmartSense Auto-tuning algorithm for dynamic sensor performance maintenance
Liquid tolerance capabilities to eliminate false touches in wet conditions
System diagnostics to detect improper capacitor values and sensor shorts

Applications

Capacitive touch user interfaces replacing mechanical buttons
Proximity sensing solutions with wake-on-approach functionality
Industrial control panels requiring noise immunity and reliability

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to ensure correct packaging and reel specifications. Confirm that the component matches the required package type and environmental ratings for the intended application before procurement.

Selection Notes

Select this model when a design requires up to 16 sensing inputs combined with proximity detection capabilities. Ensure the host system supports I2C communication and that the operating voltage aligns with the 1.71 V to 5.5 V specification range.

Part Context

This component belongs to the CY8CMBR3xxx family of CapSense Express controllers developed by Infineon Technologies (formerly Cypress Semiconductor). The family provides register-configurable solutions for capacitive sensing applications without requiring custom firmware development.

Replacement Considerations

Consult the official datasheet selector guide for compatible alternatives within the CY8CMBR3xxx family. Verify pin compatibility and feature sets such as slider support or shield electrode requirements when considering substitutes.
