CPT212B Capacitive Touch Controller

TouchXpress™ Family CPT212B Data Sheet The CPT212B device, part of the TouchXpress family, is designed to quickly add capacitive touch via an I2C interface by eliminating the firmware complexity and reducing the development time for capacitive sensing applications. Supporting up to 12 capacitive sensor inputs in packages as small as a 3 mm x 3 mm QFN, the CPT212B is a highly-integrated device that interfaces via I2C to the host processor to provide a simple solution for adding capacitive touch.

CPT212B Features

* like moisture immunity, wake-on proximity, and buzzer feedback for an enhanced user experience. No firmware development is needed, and all the capacitive touch sense parameters can be configured using a simple GUI-based configurator. By eliminating the need for complex firmware development, the CPT2
