Atmel equips MCUs with Quantum capacitive touch tech

AtmelCorp. has licensed Quantum ResearchGroup's QTouch and QMatrix capacitive touch technologies to be programmed into Atmel picoPowerAVR microcontrollers, enabling the devices to be used for both touch sensing and control functions such as driving motor controls, LEDs and displays.

QTouch technology is used for simple keys, while QMatrix is used for larger keypad arrays and keyboards. Atmel has also obtained a license to QWheel and QSlide applications, which are used for rotary and linear touch controls respectively.

Atmel's planned capacitive touch parts will incorporate AVR microcontrollers with picoPower energy-saving techniques. The MCUs have a modern and effective core suited for Quantum's touch technologies. The AVR architecture also ensures both high processing capability and good performance. In addition, its true 1.8V operation and multiple sleep modes increase the battery life in hand-held, battery-operated products such as cellphones and media players.

"The combination of the AVR core, picoPower technology and robust capacitive sensing based on our patented charge-transfer methods will give customers reliable, proven, low energy capacitive touch sensing solutions at a competitive price point," said Hal Philipp, founder and CEO of Quantum.

"Atmel selected Quantum technology for its entry into the capacitive touch sensing market after evaluating all the available technologies," said Ingar Fredriksen, director AVR product marketing. "We wanted to go with a solution that integrates rapidly with our technology and works reliably in challenging environments. When parts hit the market, designers will have a flexible low-power alternative with strong field and factory support, backed by Atmel's reliable supply chain."
