Atmel's New Family of Touch Screen Solutions Enable Two Touch Gestures for Intuitive User


SAN JOSE, Calif., Oct. 23 /PRNewswire-AsiaNet/ --

New Product Line also Includes First to Market Single Layer ITO Touchscreen 

                   Solutions for Single Touch Applications 


    Atmel(R) Corporation (Nasdaq: ATML) today announced its new line of charge-transfer, capacitive

touchscreen controller ICs targeted at some of the highest growth areas of the electronics market, such as

mobile phones and other personal electronics. Atmel, with millions of custom touchscreen solutions shipped

over the past few years, offers highly reliable standard Two Touch(TM) and Single Touch touchscreen

controllers. Together with partners, the company also offers complete touchscreen solutions for the most

common screen sizes, including the chips and sensors, typically implemented as ITO on PET or glass. 

    Atmel's Two Touch controller ICs can track and report one or two 

simultaneous touches as separate X and Y positions. Common user initiated gestures, including tap, double

tap, flick and drag, as well as two touch gestures such as zoom in, zoom out and rotate are implemented in


touchscreen controllers. This approach allows designers to incorporate a 

comprehensive range of user interface functions such as resizing and rotation 

of on-screen graphics, as well as allowing a two finger gesture to replace multiple levels of menu access.  

    In addition to the touchscreen functions, the engineer can also implement 

the touch surface as a combination of touch keys and scrolling devices for additional flexibility -- this is

configurable by the host processor through 

the industry standard two-wire, I2C compatible interface. 

    Peter Jones, General Manager of Atmel's microcontroller division said, "Our new Two Touch devices give

industrial designers the opportunity to 

incorporate next generation, cost effective user interfaces into their new product developments with ease. To

support this activity our End-to-End 

reference designs help speed the development cycle. These new products 

overcome many of the limitations of traditional resistive and capacitive 

touchscreen technologies. Also with our single layer ITO solutions, customers 

can achieve excellent performance at a very competitive price." 

    For single touch applications, Atmel offers a unique single layer sensor 

minimizing the mechanical stack, and improving the optical performance of touchscreen displays. The

reduction of scatter and absorption of the available 

backlight results in improved light transmission, contrast and results in highly reduced power consumption.  

    The first Two Touch devices, AT42QT5320 and AT42QT5480, support screen sizes of up to 8" with a 16:9

aspect ratio. The single touch devices, 

AT42QT4120 and AT42AT4160, support screen sizes of up to 4.3" with aspect ratios of 16:9 or 4:3. The

AT42QT5320 comes in a 5x5 mm QFN package; the AT42QT5480 is available in 5x5 mm BGA, a 7x7 mm

QFN and a 10x10mm TQFP package 

and also supports up to four user controlled GPO's. All packages are RoHS compliant. 

    The AT42QT4160 and AT42QT4120 single touch devices can operate through up 

to 3mm plastic and 4mm glass panel thicknesses. The devices are available in a 

5x5 mm QFN RoHS compliant package. 


    Availability and Pricing 

    Samples are now available and production quantities will be available in 

Q1 2009. Pricing for touchscreen controller devices start at $2.50 for high volume projects.
