TouchXpress™ Family CPT112S Data Sheet The CPT112S 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 a 3 mm x 3 mm QFN package, the CPT112S is a highly-integrated device that interfaces via I2C to the host processor to provide a simple solution for adding capacitive touch. The device also comes with advanced 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.
