Supporting up to 12 capacitive sensor inputs in packages as small as a 3 mm x 3 mm
QFN, the CPT112S is a highly-integrated device that interfaces via I2C to the host pro-
cessor 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 ca-
pacitive touch sense parameters can be configured using a simple GUI-based configura-
tor. By eliminating the need for complex firmware development, the CPT112S device en-
ables rapid user interface designs with minimal development effort.
