The Atmel® maXTouch® family, known for its superior performance and rich feature set, is now qualified for automotive applications, such as automotive touchscreens and touchpads (supporting 2 inches up to 12 inches in diameter) used in center stack displays, navigation systems, radio human-machine interfaces (HMIs) and rear-seat entertainment systems.

maXTouch devices provide unlimited touch identification, fast response time, exacting precision, robust operation and low power consumption to touch-based designs.

The automotive-qualified maXTouch family member mXT224E provides dedicated functionalities that meet specific automotive requirements such as high-temperature behavior and reliable operation in harsh environments.

Embedded filters realized in hardware and firmware enable touchscreens supporting gloved finger operation―a key requirement in modern automotive HMI interfaces. Embedded single- and dual-gesture algorithms and the palm suppression functionality allow detection and suppression of unintended touches, such as a resting hand on the screen.

The mxT224E addresses medium-sized touchscreens of up to 6 inches in diameter. Qualified for automotive from -40°C to +85°C, it supports configurable X- and Y-lines, as well as gloved operation.
