产品概述

• 产品概述

  CY8CMBR3108-LQXIT is a CapSense® Express™ controller that is enable advanced, yet easy-to-implement, capacitive touch sensing user interface solutions. It is ideal for implementing capacitive buttons, and proximity sensing solutions with minimal development-cycle times. The CY8CMBR3xxx family features an advanced analogue 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. Advanced features, such as LED brightness control, proximity sensing, and system diagnostics, save development time. This controller enables robust liquid-tolerant designs by eliminating false touches due to mist, water droplets, or streaming water.
