Create 2D Touchpads and Touchscreens with a Microcontroller
It’s Easy and Very Economical
Many of our microcontrollers (MCUs) feature on-chip capacitive touch engines. With these MCUs, you can control a touchpad or touchscreen without any additional cost. Our free 2D Touch Surface Library with built-in gesture recognition brings 2D surfaces to life to enhance the user experience for your products.The library runs in the background and interfaces easily with your applications or communications code for a true one-chip 2D touch platform.
We also offer easy-to-use hardware tools and code configurators to accelerate your development and speed up your time to market with your new touch-enabled products. Our global team of applications engineers will also support you when you come across any challenges or have any questions.

How Does 2D Capacitive Touch Technology Work?
- Projected capacitive touch sensors operate by measuring the tiny change in capacitance on an electrode when a human finger or other object comes in contact with a sensor grid underneath the touch surface
- An on-chip touch peripheral is used to take separate measurements of the capacitance on all electrodes to determine the position of the finger
- Additional on-chip processing functions are used to detect surface gestures like swipes and report them to the application software
Do You Need High-Performance Multi-Touch or Large Touchscreens?
maXTouch touch controllers support multi-finger, gloved-finger and wet operation for screens up to 24” in diagonal size that are used in a variety of automotive, home appliance, medical and industrial applications. Regardless of the conditions, maXTouch® touchscreen controllers are designed for robust and reliable operation in challenging environments. Host serial I2C, SPI and USB communication interfaces are available across the product portfolio.
