Infineon Technologies CY8CMBR3xxx CAPSENSE™ Express™ Controllers
Infineon Technologies 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.
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 Infineon's 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.
