Re-engineering the Touchscreen Experience for Smartphones, Tablets and a Host of Displays

Building on 15 years of touch innovation, Atmel® maXTouch® technology delivers next-generation controller capabilities for touchscreen applications, including both superior performance and low power consumption. It enables touch interfaces that identify, qualify and track the user’s contacts with exceptional precision and sensitivity. With maXTouch unlimited touch, users enjoy a sophisticated interface that is smart enough to ignore unintended touches. All of this enables peerless touch interfaces that are intuitive, flexible, reliable, and battery-friendly.

Atmel touchscreen chips are small enough to fit the most compact mobile devices and powerful enough to accommodate the larger screens on products such as digital tablets and Windows 8 compliant notebooks and Ultrabooks.

Key Features

  • Unlimited touch — This unique maXTouch capability enables advanced functions invoked by simultaneous multiple touches, while helping to avoid false touches. The maXTouch T series features a dual architecture and is the world’s first single-chip touchscreen controller for Windows 8 certified notebooks and Intel Ultrabooks up to 15.6 inches. Newer devices in the maXTouch family integrate maXFusion™ sensor hub technology, which processes data from a range of sensors—including accelerometers, gyroscopes and magnetometers—to control the end product or a specific application based on real-time data related to location, direction and orientation.
  • Passive Stylus — The T series supports 1.0 mm passive stylus, enabling users to interact with their smartphone via finger tips, finger nails, a ballpoint pen, mechanical pencil, and a variety of stylus accessories.
  • Active stylus — With a high-performance 1mm tip, maXStylus® active stylus offers the convenience of pen-like operations on the touchscreen.
  • Ski Glove — The T series supports up to 5.0 mm thick glove touch operation, making the use of a smartphone in cold outdoor environment a lot friendlier than ever before.
  • Hover — The T series with 20 mm finger Hover supports simple gesture inputs without the need of touching the touchscreen. Hover adds a new dimension of user interactions for smartphone users.
  • Fast response — High scan rates enable devices to follow virtually any motion, supporting demanding applications.
  • Exacting precision — An advanced, low-noise front end and numerous sensor nodes make the screen more precise and sensitive to contact.
  • Unparalleled flexibility — The chips can be easily configured to suit a broad array of applications and screen sizes.
  • Low power consumption — The ICs "sleep" after scans to conserve power and extend battery life.
  • Small footprint — Chips are suitable for the smallest devices and require few external components, lowering system costs.
  • Robust operation — Environmental resilience and excellent noise suppression increase reliability and usability.
