CapSense MBR3 is Cypress’s solution for quickly and easily replacing mechanical buttons with sleek and reliable capacitive-sensing user interfaces. The CapSense MBR3 family is the world’s easiest capacitive-sensing solution that allows you to design with the click of a mouse using our GUI-based software tool, EZ-Click™.

CapSense MBR3 combines the best of CapSense features including SmartSense™ auto-tuning, robust water tolerance, and best-in-class proximity sensing while delivering reliable performance under all conditions. The CapSense MBR3 family comes in four small packages that are suited for various capacitive-sensing designs.

Easiest-to-Design

• CapSense MBR3 requires no firmware development
• EZ-Click GUI-based software tool configures devices without the need to write any code

SmartSense Auto-Tuning

• A CapSense algorithm that continuously compensates for system, manufacturing and environmental changes
• Eliminates the need for manual tuning during all product design phases

Robust Water Tolerance

• CapSense MBR3 works under water droplets, rain, mist and other liquids
• Ensures no false touches even under streaming water

Industry's Best Capacitive Proximity Sensing

• Achieve up to 30cm in proximity sensing distance
• Implement advanced features like wake-on-approach to support ultra-low power applications

Reliable Performance

• Advanced sensing algorithms ensure reliable performance even in noisy environments
• Implement designs with Signal-to-Noise Ratio (SNR) of > 100:1
