According to Atmel Corp., Samsung Electronics Co. Ltd will be using Atmel's maXTouch mXT224E controller to power its Galaxy S II touchscreen. It is a third-generation capacitive touch engine that integrates Atmel's advanced AVR architecture optimized for capacitive sensing. An addition to the maXTouch E-series, the company said the touchscreen controller offers advanced noise rejection and suppression. The device also eases thinner touchscreen stacks, such as "on-cell" where a touch sensor is patterned directly on the color filter of the display. The support of "on-cell" and other thin touchscreen constructions allow manufacturers to take pioneering designs faster-to-market so consumers can enjoy sleeker and brighter handsets, Atmel stated.

The maXTouch 224E controller enables Samsung Galaxy S II users to experience unlimited touches, faster response times, higher accuracy, lower power and superior sensitivity, the company said. In addition, the E-series architecture noise immunity provides a flawless touch experience, even with unqualified after-market chargers and in the presence of other noise such as WiFi and microwave signals, added the company.

"Samsung continues to develop some of the most innovative touch smartphones on the market," said Helen Francis, senior manager of touch marketing, Atmel. "Atmel is thrilled to be powering Samsung's next-generation smartphone touchscreens with our enhanced maXTouch solutions. Samsung's confidence in Atmel's touch technology is further evidence that we continue to lead the market with ideal solutions for the most innovative touchscreen devices."
