Overview

The CY8CMBR3102-SX1I is a dedicated CapSense Express controller designed for implementing two capacitive touch buttons without the need for firmware development. It operates across a wide voltage range of 1.71V to 5.5V and is optimized for ultra-low power consumption, drawing as little as 2.5uA in sleep mode.

Why Choose This Part

The SmartSense Auto-tuning algorithm eliminates the need for manual sensitivity tuning, simplifying the design process for varying PCB thicknesses and overlay materials. Its 8-pin SOIC footprint is compact, and the dedicated I2C and GPO interfaces allow for easy integration into existing host systems.

Applications

Mechanical Button Replacement
Replacing traditional mechanical switches with sleek, wear-resistant capacitive touch interfaces in consumer electronics.
Proximity Sensing
Detecting the presence of a hand or finger to wake a system from sleep mode, reducing overall power consumption.
Industrial Control Panels
Providing a sealed, robust user interface for equipment in environments where dust or moisture may interfere with mechanical contacts.

Getting Started

Engineers can configure the device using the EZ-Click software tool, which allows for rapid prototyping of sensor parameters via an I2C interface. For hardware evaluation, look for the CY8CKIT-145-40XX or similar CapSense evaluation kits that demonstrate the MBR3 family's liquid tolerance and proximity features.
