TouchXpress™ Family CPT213B Data Sheet The CPT213B device, part of the TouchXpress family, is designed to quickly add IEC 60730 Class B capacitive touch via an I2C interface by eliminating the firmware complexity and reducing the development time for capacitive sensing applications.
Supporting up to 13 capacitive sensor inputs in packages as small as a 4 mm x 4 mm QFN, the CPT213B 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 an IEC safety library and moisture immunity.
No firmware development is needed, and all the capacitive touch sense parameters can ...
