Smart, Sleek and Sophisticated

With Atmel® maXTouch S Series devices, you get an array of features and capabilities that enable a superior user experience: intelligent touch processing algorithms, unparalleled noise suppression, high responsiveness, pinpoint precision and sensor hub technology that fuses together input from motion-processing sensors such as accelerometers, gyroscopes and magnetometers. Build a highly responsive, high-fidelity touch experience in mobile devices from smartphones to Windows® 8-compliant Ultrabooks™ and more—even in the most punishing noise environments. Deliver an enhanced customer experience, especially with applications such as gaming and navigation.

Integrated Sensor Hub Functionality

Vivid Displays

Enhance gaming, navigation and similar applications by integrating real-time location, orientation, direction and inclination data with maXFusion™ sensor hub technology, which fuses sensor inputs from accelerometers, gyroscopes and magnetometers. With maXFusion technology, you can simplify design of low-power, Windows 8-based tablets, notebooks and Ultrabooks, while enhancing the device motion experience for your customers. maXFusion technology delivers accurate sensor processing, optimized latency and low current consumption to Windows 8 products. maXFusion technology can also be used to bring real-time motion processing to Android-based devices.

maXFusion technology is also available in standalone Atmel microcontrollers. The Atmel mXF0100 is a complete Windows 8-certified sensor hub solution based on an Atmel AVR® microcontroller and maXFusion technology. maXFusion technology provides maximum flexibility in sensor support, working with devices from Atmel's sensor partners including the most popular sensors selected by smartphone and tablet manufacturers. You can also use low-power Atmel AVR® UC3L microcontrollers and your own firmware to perform sensor fusion processing.

More Vivid Displays

Build thinner, lighter smartphones, tablets, notebooks and ultrabooks with brighter, more vivid displays. A key maXTouch S Series feature, our thinner sensors let you use the latest sensor constructions with the noisiest displays, while still delivering unbeatable touchscreen performance.

Flawless Touch Performance

Enable your customers to achieve flawless touch performance using any charger. maXCharger™ Technology, another key maXTouch S Series feature, makes charger noise control possible.


Shorter Design Cycle

You won't need to develop any firmware to configure your controller to a particular touch sensor stackup, display or charger. And best of all, our thinner sensors require no synchronization to the display or dedicated listening channels. So maxTouch S Series devices are as easy to develop with as previous-generation maXTouch devices.
