Atmel ships second-gen maXStylus Active Pen


Atmel is now shipping its second generation Windows 8.1-certified maXStylus in volume quantities. The new capacitive active stylus controller delivers a near-perfect ‘pen-to-paper’ writing experience on a touchscreen with superior responsiveness.

According to Shar Narasimhan, Atmel Sr. Product Marketing Manager of Touchscreen and Stylus Products, touchscreens ranging from 6” to 15.6” using Atmel’s maXTouch controllers can seamlessly support maXStylus without additional hardware components or design changes.

“These solutions include our recently launched maXTouch T Series devices ranging from the mXT640T to the mXT2952T single-chip solutions. This integrated solution eliminates the need for an additional sensor layer, lowering overall system costs for the OEM without compromising performance,” Narasimhan explained. “The complete maXTouch and maXStylus solution has achieved Microsoft’s Windows 8.1 certification and can be [easily] integrated into [Microsoft] Windows 8.1 or [Google’s] Android OS.”

Narasimhan also noted that Atmel’s Stylus heralds a new era of interaction with smart devices as users seek a more intuitive experience on their smartphones, tablets, notebooks and Ultrabooks.

“These smart devices also require richer feature sets to differentiate their products,” he said. “We deliver the closest pen-to-paper experience available today for users writing with a capacitive active stylus on a touchscreen. Our next-generation maXStylus pen is currently in mass production with tier 1 OEMs and will be available on store shelves in early Q1.”

Today, competing active stylus solutions compromise the noise immunity and power levels of a system as the touchscreen struggles to distinguish between the pen and the user’s fingers. This degrades the overall system power consumption, signal-to-noise (SNR) ratio and pressure sensitivity resulting in missing strokes, dropped touches, poor linearity and an overall inferior user experience. 

With Atmel’s integrated solution, the maXStylus mXTS200 uses intelligent scanning and synchronization with the touch controller to deliver a higher SNR ratio. This results in the best capacitive stylus writing experience available on the market today – without comprising the touch controller’s noise immunity and power consumption of the overall system.

In addition, the maXStylus mXTS200 features intelligent palm rejection and the capability to switch from writing with a stylus to using both large and small fingers, without degrading capacitive touchscreen touch performance.

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.”

Designing the future of touch with Atmel

Atmel CEO Steve Laub probably put it best when he told the Wall Street Transcript that touch is generally considered to be the preferred method for current-gen consumers to interface and interact with electronic devices.

“For the last three years, [Atmel has] been the world’s leading provider of mobile touch solutions, so our technology and products are changing the way people use and interact with electronic [devices],” Mr. Laub explained. “Our technology is also changing how they view the world and the ability to interact with the world.”

Indeed, Atmel has achieved a number of impressive milestones in the touch space over the last 6 months including:

XSense: A high-performance, highly flexible touch sensor which allows engineers to design devices with curved surfaces and even add functionality along product edges. Atmel is now positioned to ramp volume production for this revolutionary new tech.

Facilitating an uber-thin wireless touch interface: Cambridge Silicon Radio (CSR) developed an uber-thin wireless touch interface. The flexible interface, measuring less than 0.5 mm thick, turns any area into a touch surface for mobile devices and even desktops. To create the ultra-thin wireless touch surface, CSR partnered with Atmel and Conductive Inkjet Technology (CIT). More specifically, the device uses Atmel’s touch silicon tech to sense multiple contact points on a surface – and is therefore capable of offering a full touch surface or power optimized key detection.

Expanding the maXTouch auto lineup: In July, Atmel rolled out a new maXTouch family to facilitate single-layer shieldless designs in automotive center stacks, navigation systems, radio interfaces and rear seat entertainment platforms. The mXT336S is optimized for 7-inch touchscreens, while the mXT224S targets smaller touchscreens and tablets.

Powering the Samsung Galaxy S4 Mini’s touchscreen: Samsung selected Atmel’s maXTouch mXT336S controller to power the touchscreen of its Galaxy S4 Mini.

Powering Samsung’s Galaxy S4: The Galaxy S4 is fitted with Atmel’s sensor hub management MCU (microcontroller unit) which collects and processes data from all connected sensors in real-time, optimizing multiple user experiences, such as gaming, navigation and virtual reality. In addition, the sensor hub MCU lowers the overall system power consumption via picoPower technology to prevent drain and enable longer battery life.

Driving Asus touchscreens: Asus selected Atmel’s mXT2952T and mXT1664T controllers to drive the touchscreens of multiple new tablets and Ultrabooks – including the Zenbook Infinity which is based on Intel’s Haswell processor.

Enabling ‘in-cell’ touch for custom LCD designs: AndersDX introduced In-Cell Touch technology custom liquid crystal display (LCD) installations targeted at low- to high-volume consumer manufacturing. Instead of a touch sensor bonded onto the LCD display, each In-Cell touch key is embedded directly into the LCD cell. The LCD ITO pattern is then designed to match individual touch key symbols. An Atmel Q Touch sensor IC integrated into the display electronics controls up to four touch keys per application.

Outdoors with Ocular: Atmel’s maXTouch S trekked to the great outdoors with Ocular LCD’s PCAP touch panels. Designed specifically for outdoor and marine applications, these Crystal Touch panels are non-birefringent and immune to false touches caused by water spray and droplets.

Atmel’s maXTouch T controllers power Asus touchscreens

Asus has selected Atmel’s recently launched mXT2952T and mXT1664T controllers to power the touchscreens of multiple new tablets and Ultrabooks – including the Zenbook Infinity which is based on Intel’s Haswell processor.

Part of Atmel’s latest generation maXTouchT Series, the mXT2952T is the world’s first ultra low-power single chip touchscreen controller for 15.6” displays, while the mXT1664T targets displays up to 12.5”.

“Our new maXTouch T Series controllers feature adaptive sensing architecture designed to combine processor intelligence, along with mutual and self capacitance,” a senior Atmel marketing manager told Bits & Pieces.

“This architecture seamlessly transitions into the best mode in real-time to enable superior touch and active stylus performance in adverse environmental conditions, while minimizing overall power consumption.”

The marketing manager also noted that Atmel’s maXTouch T Series supports the active maXStylus, which offers users a more precise handwriting experience on their touchscreens. Meanwhile, additional features such as sensor hub management, smaller package size and native fine-line metal mesh support enable OEMs to develop sleeker form factors.

As previously discussed on Bits & Pieces, Atmel has been the world’s leading provider of mobile touch solutions for the last three years – positively impacting the way people use and interact with electronic products.

“If you think about the most common electronic device today, a cell phone or smartphone, people use touch technology to interact with it. Today, touch is generally considered to be the preferred way for people to interface or interact with electronic devices,” Atmel President and CEO Steve Laub told the Wall Street Transcript during a recent interview.

“A key goal for us is to enhance our leading position in the capacitive touch market. In 2012, for the third year in a row, we were the leader in the mobile capacitive touch marketplace. We are powering millions of tablets and smartphones, and we want to continue our leadership position [in a] very rapidly changing, dynamic marketplace.”
