CPT007B

TouchXpress™ Family CPT007B Data Sheet The CPT007B device, part of the TouchXpress family, is designed to quickly replace mechanical buttons with modern capacitive touch buttons by eliminating firmware complexity and reducing development time. Supporting up to 7 capacitive sensor inputs in a 3 mm x 3 mm QFN package, the CPT007B is a highly-integrated device that provides a simple solution for adding capacitive touch. The device also comes with advanced features like moisture immunity, wakeon 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. The CPT007B device is ideal for a wide range of capacitive touch applications, including the following: Home appliances Instrument / Control panels White goods Medical equipment Consumer electronics Lighting control KEY FEATURES No firmware development required Simple GUI-based configurator 7 Capacitive Sensor inputs with programmable sensitivity 7 General purpose outputs (GPOs) to communicate to the host processor or drive LEDs Lowest power capacitive sense solution Active — 200 µA Sleep — 1 µA Wake on proximity Superior noise immunity: SNR up to 270:1 Moisture immunity Mutually-exclusive touch qualifier ...
