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. The CY8CMBR3xxx family features an advanced analog sensing channel and the Capacitive Sigma Delta PLUS (CSD PLUS) sensing algorithm, which delivers a signal-to-noise ratio (SNR) of greater than 100:1 to ensure touch accuracy even in extremely noisy environments. 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. The CY8CMBR3xxx controllers are offered in a variety of small form factor industry-standard packages. The ecosystem for the CY8CMBR3xxx family includes development toolssoftware and hardwareto enable rapid user interface designs. For example, the EZ-Click Customizer tool is a simple graphical user interface software for configuring the device features 2 through the I C interface. This tool also supports CapSense data viewing to monitor system performance and support validation and debugging. Another tool, the Design Toolbox, simplifies circuit board layout by providing design guidelines and layout recommendations to optimize sensor size, trace lengths, and parasitic capacitance. To quickly evaluate the CY8CMBR3xxx family features, use the CY3280-MBR3 Evaluation Kit.
