Applications of CY8CMBR3108-LQXIT
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.
