Turnkey Microcontrollers With Capacitive Touch

Ready-to-Use Solutions for Buttons, Sliders, Wheels and Proximity

Whether you are new to developing touch-enabled designs, or just looking for a quick, easy and reliable solution for your design, our turnkey capacitive touch controllers provide a simple and straightforward pathway for implementing touch capabilities in your user interface. These devices communicate with the host via GPIO or the standard I²C, SPI and USB serial interfaces. You don’t need any programming experience to get them working. Simply connect the sensor and apply power. Use the simple Graphical User Interface (GUI)-based configuration tool to tune the controller and monitor the touch signals. These plug-and-play products also enable you to easily replace mechanical buttons in your existing product. We have options that support up to 64 buttons, water-tolerant touch and EN/IEC 60730 requirements for Class B safety.
