Automotive qualified touch controllers from Atmel

Atmel's new maXTouch family of touch controllers is designed to enable single layer shieldless designs in automotive centre stacks, navigation systems, radio interfaces or rear seat entertainment systems.

The mXT336S is optimised for 7in touchscreens, while the mXT224S targets smaller touchscreens and touchpads. Both devices are AEC-Q100 compliant and fully automotive qualified. Atmel claims they offer faster response time, more precise touches, robust operation and low power consumption. The devices support touch detection, up to 10 simultaneous touches, touch size reporting, single and dual touch gesture calculation, communication of X/Y positions, gesture support, and the ability to eliminate unintended touches. Users can perform multi touch gestures such as pinch and stretch, while unintended touches are rejected, such as a resting hand on the screen.
