With Atmel® touch technologies, human interfaces are intuitive, uniquely personal, and simply fun to use. From our touchscreen controllers to our touch sensors and everything in between, we provide technologies that enable you to produce smart and differentiated designs that delight your customers. We’ll meet your high-performance standards, not to mention your power consumption expectations. With our configuration options, you’ll be able to implement our chips in all kinds of applications.

  • Highly Evolved Touchscreen Controllers with Best-in-Class Capacitive Touch Technology — Our maXTouch® touchscreen controller technology delivers superior performance and low power consumption, enabling touch interfaces that identify, qualify, and track the user’s contacts with exceptional precision and sensitivity, while ignoring unintended touches. Our latest T series of devices provides an exceptional touch performance that supports finger, thin stylus, thick glove, and Hover operations, as well as robust touches even when the touchscreen is coated with moisture or rain drops.
  • Sensor Hub — Our maXFusion technology is also available in a standalone solution, the mXF0100, which accurately processes real-time data related to location, direction and orientation for use in handsets and tablets. In addition, you can also use a standard Atmel microcontroller, such as a low-power Atmel AVR® UC3L device integrated with your own sensor fusion code, to perform sensor fusion processing with sensors provided by our extensive range of sensor partners.
  • Touch Sensors — Our XSense® touch sensors provide a highly flexible, high-performance alternative to traditional touch sensors, enabling you to develop light, sleek touch-based designs that are edgeless, have narrow borders and boast curved surfaces.
  • Buttons, Sliders and Wheels — Our market-proven technology for implementing nonmechanical buttons, sliders and wheels offers excellent precision and reliability on any touch-sensitive device. The technology delivers low power, and low cost, and supports simple configurations of 1 to 10 buttons up to scanned-matrix configurations with 48 buttons.
  • Atmel QTouch Library — Atmel QTouch® Library makes it simple for you to embed capacitive-touch buttons, sliders and wheels functionality into general-purpose Atmel ARM and AVR® microcontroller applications. The royalty-free QTouch Library provides several library files for each device and supports different numbers of touch channels, enabling both flexibility and efficiency in touch applications.

Transform the User Experience with Atmel Touch Controllers

For the user, touch technology is all about sensitivity, speed, and accuracy— in other words, an interface that senses and responds to their touches precisely and reliably, in the blink of an eye.

As a global leader in capacitive touch technology, with more than 15 years of experience, Atmel can be your partner in delivering transformative touch innovations to the market quickly and cost effectively. Our robust noise-resistant integrated circuits (ICs) are designed to provide superior performance and response times while conserving power and saving space. For enhanced functionality and design ease, you can also integrate our touch technology with leading-edge Atmel ARM and AVR® microcontrollers.
