IFXCY8CMBR2044-24LKXIT

Overview

The CY8CMBR2044-24LKXIT is a CapSense Express controller designed for implementing up to four capacitive touch buttons without the need for firmware development. It operates over a wide voltage range of 1.75V to 5.5V and features SmartSense auto-tuning to compensate for environmental changes and manufacturing variations. The device includes integrated LED drivers and consumes as little as 15uA per button in low-power configurations.

Why Choose This Part

This controller eliminates the complexity of capacitive sensing through SmartSense Auto-Tuning, which dynamically adjusts sensitivity and thresholds. It provides a complete hardware-configurable solution that includes system diagnostics and LED drive capabilities in a compact 3x3mm QFN package.

Applications

Getting Started

Designers can evaluate the device using the CY3280-MBR2 CapSense Express Kit. The hardware is configured via the EZ-Click software tool, which generates the required configuration settings for the device's I2C or serial debug interface.
