Heilbronn, Germany--Atmel Corp., pushing its consumer technology
into the automobile, announced version of its maXTouch
microcontrollers for in-car control systems. The 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.
The high signal-to-noise ratio of 80:1 makes these devices ideal for very noisy environments. The devices provide full support for gloved hand operation on automotive touchscreens and pads.
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 (pinch, stretch, etc.), 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.
