TouchXpress™ Capacitive Touch Controller

TouchXpress capactive touch controllers are designed to quickly replace mechanical buttons with modern capacitive touch buttons. The controllers support up to 13 capacitive sensor inputs and eliminate complex firmware to speed user interface design. The devices are highly integrated and can include I2C interfaces to the host processor. No firmware development is needed, and all the capacitive touch sense parameters can be configured using a simple GUI-based configurator.
