Atmel debuts mXT106xT2 touchscreen controller lineup

Atmel has expanded its popular maXTouch T lineup of touchscreen controllers with the mXT106xT2 family of devices. The new series incorporates a wide range of features for 7 – 8.9″ mid-sized tablet displays including hover, stylus and optimized noise immunity.

As Atmel exec Patrick Hanley points out, the maXTouch is the only product currently available that enables finger hovering up to 20mm on devices larger than a smartphone. This capability allows users to interact with their devices – without physically making contact with the screen.

Indeed, the T Series incorporates Atmel’s Adaptive Sensing technology to facilitate dynamic touch classification, which automatically switches between self- and mutual-capacitance sensing – providing a seamless transition between finger touch, hover, passive or active stylus, as well as glove touch. Additionally, Adaptive Sensing dramatically reduces power consumption, facilitating longer battery life for mobile devices.

“The mXT106xT2 offers features required in today’s tablet devices, including 0.4mm thin cover lenses and multifinger glove support for users in cold weather climates,” said Hanley. “For [those] who seek the extensive benefits in going paperless, the mXT106xT2 also [includes] stylus capabilities in either active stylus through Atmel’s maXStylus, or passive stylus with a 1mm tip to facilitate more precise selection.”

Essentially, the 106xT2 offers the same performance features as Atmel’s T Series maXTouch controllers, while enabling capacitive button, slider and wheel control via an embedded hardware module known as the Peripheral Touch Controller (PTC). This feature allows systems to integrate capacitive buttons without tying up nodes from the touch controller, while performing with improved noise immunity and lower power than when implemented via firmware.

The new devices in the maXTouch T Series are currently in production, with the 8.3” screen size evaluation kit slated to ship in May.

Atmel’s maXTouch T hits next-gen smartphone and phablet markets

Atmel has expanded its popular maXTouch T lineup of touchscreen controllers with the mXT640T, mXT336T and mXT224T. The new devices offer a comprehensive set of features, supporting next-gen mobile devices such as smartphones, phablets and mid-size tablets with touchscreens ranging from 3.2”-8.3.”

Key touch features include 1mm passive stylus and maXStylus (active stylus), hover capability, moisture immunity and multi-finger glove support.

“Essentially, these devices build on Atmel’s success of its single-chip maXTouch T series products for large-screen applications – mXT2952T and mXT1664T – which were launched in the second quarter,” an Atmel engineering rep explained.

As we’ve previously discussed on Bits & Pieces, the T series deftly incorporates Atmel’s Adaptive Sensing technology to enable dynamic touch classification – automatically and intelligently switching between self- and mutual-capacitance sensing. This provides users with a seamless transition between a finger touch, hover, passive/active stylus or glove touch. Meaning, users no longer have to manually enable “glove mode” in the operating system to differentiate between hover and glove.

Adaptive Sensing also helps significantly reduces the power consumption of a device, thereby extending battery life. Meanwhile, the analog front-end is equipped with advanced and flexible settings to maximize the signal-to-noise ratio (SNR) prior to digital processing – eliminating signal distortions induced by water and noisy chargers.

“The new T Series enables superior touch performance with single-layer sensors as compared to the most recently announced solutions. Simply put, the latest devices will enable Atmel to extend its industry leadership in the large-screen market to the smartphone and phablet spaces,” said the engineering rep. “In fact, we are already working with a range of ITO and LCD manufacturers to support various stack-ups such as OGS, G1, GF and On-Cell which are targeted for production early next year. Plus, Atmel has begun sampling the new T Series devices with a number of OEMs who have provided positive feedback about the new touch products and their performance.”
