The CY8CMBR3xxx CapSense® Express™ controllers enable advanced, yet easy-to-implement, capacitive touch sensing user interface solutions. This register-configurable family, which supports up to 16 capacitive sensing inputs, eliminates time-consuming firmware development. These controllers are ideal for implementing capacitive buttons, sliders, and proximity sensing solutions with minimal development-cycle times. These controllers are enabled with Cypresss SmartSense™ Auto-tuning algorithm, which compensates for manufacturing variations and dynamically monitors and maintains optimal sensor performance in all environmental conditions. In addition, SmartSense Auto-tuning enables a faster time-to-market by eliminating the time-consuming manual tuning efforts during development and production ramp-up. Advanced features, such as LED brightness control, proximity sensing, and system diagnostics, save development time. These controllers enable robust liquid-tolerant designs by eliminating false touches due to mist, water droplets, or streaming water.
