maXTouch U family opens up a world of possibilities for next-gen devices


This new controller family will make touchscreen devices less frustrating and more enjoyable to use.


It’s safe to say that touchscreens have surely come a long way since Dr. Samuel C.Hurst at the University of Kentucky debuted the first electronic touch interface back in 1971. Despite their ubiquity today in just about every device, the technology doesn’t seem to always work as well as it should given recent advancements. As VentureBeat’s Dean Takahashi points out, displays remain frustratingly unresponsive to finger taps, consume a lot of power, and quite frankly, are still pretty bulky — until now.

Chips

That’s because Atmel has launched a next generation of sensor chips that will pave the way to much better (and more delightful) tactile experiences for gadgets ranging from 1.2” smartwatch screens to 10.1” tablet displays. Following in the footsteps of its older siblings, the new maXTouch U family will enable optimal performance, power consumption leveraging picoPower technology, and of course, thinner screens.

More apparent than ever before, the use of touch-enabled machinery has exploded over the past five years. As a result, there has been an ever-growing need to develop touchscreens with extremely high touch performance, ultra-low power and more sophisticated industrial designs with thinner screens. Not to mention, the anticipated surge in wearables has also created a demand for extremely small touchscreen controllers with ultra-low power consumption in tiny packaging. Luckily, this is now all possible thanks to the maXTouch U family which crams pure awesomeness in a 2.5-millimeter by 2.6-millimeter space (WLCSP).

Flawless

Designers can now build extremely innovative thin and flexible touchscreen designs using single layer, on-cell and hybrid in-cell touchscreens with intelligent wake-up gestures and buttons. What this means is that, the technology can support entry-level smartphones, slick wearable gizmos, super tablets and everything in between on a full range of stack-ups.

Among the most notable features of the U include low power modes down to 10µW in deep sleep for wearables such as smartwatches, active stylus support, 1.0-millimeter passive stylus support (so users can write with things like pencils on a touchscreen), as well as up to a 20-millimeter hover distance (so that a user can answer their phone call with a wet hand). What’s more, the touch controllers can sense water and reject it as a touch action, and works with multiple fingers — even if someone is wearing gloves.

Binay Bajaj, Atmel Senior Director of Touch Marketing, explains that the recently-revelaed series provides all the necessary building blocks for futuristic mobile gadgetry. The chips are available in samples today, while production versions will be ready in the third and fourth quarters.

“Our expertise in ultra-low power MCUs and innovative touch engineering have allowed us to bring a superior series of devices to market that is truly an innovative collection to drive next-generation touchscreens. We are a leading provider of touchscreen devices to a variety of markets adopting capacitive touchscreens,” Bajaj adds.

Let’s take a closer look at the six new maXTouch U devices:

  • mXT735U is the perfect device for the entry level tablet delivering robust moisture support and excellent noise immunity for touchscreens up to 10.1″.
  • mXT640U supports touchscreens up to 6 inches. This device supports 1mm passive stylus support and thin stack support including 0.4mm cover lens for GFF stack, up to 25mm hover detection and moisture resistance.
  • mXT416U delivers extremely high touch performance including 2.5mm passive stylus, excellent moisture support, noise immunity and up to 30mm large finger touch detection.
  • mXT336U is targeted for mid-range smartphone applications, delivering a perfect balance between performance and form factor.
  • mXT308U is geared towards low-end smartphone applications emphasizing simplicity and robustness.
  • mXT144U is designed specifically for wearable applications. The mXT144U features picoPower with 10uW in deep sleep mode and is the smallest hybrid sensing touchscreen controller packaged in a 2.5mm x 2.6mm WLCSP. This device is the ideal solution for today and tomorrow’s wearable devices.
