The new Atmel maXTouch mXT112E controller from Atmel Corporation is optimized for 2.8- to 3.5-inch touchscreens for consumer markets such as feature phones, digital still cameras, global positioning systems (GPS), gaming consoles, and other high-volume devices. The new controllers include all the proven functions of the maXTouch E series tailored to meet the precise needs of these consumer devices.
The Atmel maXTouch mXT112E enables true single-layer touchscreens, resulting in screens that are thinner, lighter and brighter. Similar to the Atmel E-series family, this device offers advanced signal processing algorithms to mitigate noise from a wider range of LCD displays, environmental noise, and interference from after-market chargers.
The mXT112E allows up to four simultaneous touches, a level of performance that has previously only been seen in the smartphone market. Similar to other maXTouch E series products, its advanced touch processing rejects unintentional touches caused by a gripping hand, while interpreting light touches correctly for gestures made on the devices. It can support a narrow passive stylus input even while the user’s hand is resting on the screen in a natural writing position.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
