Industry's First Touch Solution for Gloved Finger Operation Now Supports Touchpads Up to 7 Inches in Automobiles.
Atmel announced new automotive-qualified maXTouch controllers for in-car control systems. These new devices will bring today’s smartphone experience into contemporary cars, even for drivers wearing gloves. Expanding the Atmel portfolio of maXTouch automotive-qualified devices, the new mXT143E and mXT224E touch controllers are designed for small automotive touchscreens and touchpads up to 7 inches in diameter such as center stack displays, navigation systems, radio human-machine interfaces (HMIs) and rear-seat entertainment systems.
By addressing smaller screen and touch-pad sizes, the mXT143E and mXT224E controllers complement the company’s growing family of automotive-qualified touchscreen controllers that support screens/pads from 2 to 12 inches in diameter. With these new automotive-qualified maXTouch devices, Atmel strengthens its position as a market-leading touch innovator and supplier. The maXTouch family is known for its superior performance and rich feature set, including unlimited touches, fast response time, touch precision, robust operation and low power consumption.
Dedicated Embedded Functionality for Automotive
The mXT143E and mXT224E are fully automotive-qualified according to AEC-Q100. The touchscreen controllers provide embedded functionalities that meet specific automotive design requirements, including high-temperature behavior and reliable operation in harsh environments and with gloved fingers.
The high signal-to-noise ratio of 80:1 makes these devices ideal for very noisy environments.
The mXT143E and mXT224E embed X/Y position calculation as well as post-processing algorithms such as eliminating unintended touches. With touchscreens and pads based on these new maXTouch controllers, users can perform multi-touch gestures, while unintended touches, such as a resting hand on the screen, are rejected. The devices feature true 12-bit touch functionality with independent X/Y tracking for up to 10 concurrent touches in real–time, allowing for the highest linearity and accuracy. Adaptation to high-resolution displays is easy and quick. The user-configurable ratio of X and Y lines supports a variety of aspect ratios from 4:3 to 16:9.
Availability
Samples of automotive-qualified mXT143E and mXT224E touch controllers are available now in TQFP48 packages. Mass production will start the end of October 2012. Demo kits for both devices are also available to support design-in and shorten time to market.
