The Atmel® maXTouch® family, known for its superior performance and rich feature set, is now qualified for automotive applications. The mXT224S targets touchscreens and touchpads with a size of up to 6 inches. In addition to its high performance, multitouch functionality, faster response time, robust operation and lower power consumption, the new mXT224S also provides embedded functionalities such as gesture calculation and filter algorithms that meet current automotive design requirements. Dedicated firmware and a high signal-to-noise ratio makes the device ideally suited for very noisy environments and provide full support for gloved-hand operation on automotive touchscreens. The mXT224S supports single-layer shieldless designs which helps to achieve thinner stacks and thus to reduce system complexity, power consumption and overall system cost.

Automotive Applications

  • Center stacks
  • Middle console touchpads
  • Navigation systems
  • Radio interfaces

Principais recursos

  • AEC-Q100-compliant and fully automotive qualified
  • High SNR ratio enables single layer, shieldless designs instead of dual or triple layers, as typical in many current applications
  • Single layer sensors enable to reduce the overall system complexity, overall cost and power consumption, and increase product yields
  • High voltage option on X-lines to double the SNR ratio
  • Supporting gloved hand operation
  • Up to 10 simultaneous touches
  • Rejection of unintended touches such as a resting hand on the screen
  • Touch size reporting
  • Single- and dual-touch gesture (pinch, stretch, etc.) calculation
  • Communication of X/Y position via I2C-compatible serial interface
