Atmel has released a new automotive-certified maXTouch element suitable for cabin control systems. The new product brings the smartphone experience to today's cars, and can be operated even when wearing gloves. New products for automotive-certified maXTouch components include the mXT143E and mXT224E touch controllers, which are designed for small car touch screens and touch panels under 7 inches in diameter. Applications include car center console display screens, navigation systems, radio people Machine interface and rear seat entertainment system.
The mXT143E and mXT224E controllers are suitable for smaller size touch screens and touch panels, further enhancing the company's expanding lineup of automotive certified touch controller series. The entire series now supports touch screens and monitors with diameters from 2 inches to 12 inches. Touch panel.
The release of these new automotive certified maXTouch components strengthens Atmel's position as a market-leading touch technology and product manufacturer. The new automotive certified maXTouch product line is known for its excellent performance and rich functions. This series of products has the characteristics of unlimited touch recognition function, fast response speed, high accuracy, stable operation and low power consumption.
The mXT768E and mXT540E components are fully automotive-certified (Grade 2, AEC-Q100 standard) products, with dedicated embedded functions that meet automotive design requirements, including support for high temperature environments, reliable operation in harsh environments, and support for gloved fingers Touch.
The new product has a high signal-to-noise ratio of 80: 1, which is very suitable for noisy environments, and fully supports users wearing gloves to operate car touch screens.
The mXT143E / mXT224E components also embed X / Y position calculation and post-processing algorithms to eliminate false touches. Users can perform multi-touch gestures (contract, stretch, etc.), and at the same time distinguish and prevent palms from resting on the screen and other accidental touches.
The new component provides true 12-bit touch function, supports independent X / Y position tracking with simultaneous touch of up to 10 fingers, provides the highest linearity and accuracy, and is easy to quickly apply to high-quality displays. Users can configure the X-ray and Y-line ratio functions to support a variety of display screen ratios from 4: 3 to 16: 9.
Stephan Thaler, Marketing Director of Atmel Automotive Touch Products, said: "Atmel brings the touch experience of consumer products to the car, even if the driver wears gloves. It can be operated by using the mXT768E and mXT540E components. With a single controller, smaller-sized automotive touch applications such as center console touch screens or curved touch panels can be realized, which reduces development time, reduces system complexity and cost. "
Other features of maXTouch components for automotive applications include frequency hopping during pulse generation, self-calibration, integrated detection to meet EMI / EMC requirements, and maintaining high reliability in harsh environments. The product has a scan speed of up to 280 Hz, allowing design engineers to provide character recognition for the alphanumeric input to the automotive HMI interface, which is another key feature of modern automobiles.
Atmel can now provide samples of automotive certified mXT143E and mXT224E touch controllers in TQFP48 packages, and mass production will begin at the end of October 2012. Atmel also provides demonstration kits for these two components to support design adoption and shorten time to market.
