QFN, the CPT007B is a highly-integrated device that provides a simple solution for add-
ing capacitive touch. The device also comes with advanced features like moisture im-
munity, 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 CPT007B device enables rapid user interface designs with
minimal development effort.
