CY8CMBR3108LQXIT

Description

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.
