The Atmel® maXTouch® family, known for its superior performance and rich feature set, is now qualified for automotive applications. The mXT336S is optimized for 7-inch touchscreens and enables single-layer shieldless designs. In addition to its superior performance, multitouch functionality, faster response time, robust operation and lower power consumption, the new mXT336S 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.

Automotive Applications

  • Center stacks
  • Navigation systems
  • Radio interfaces
  • Rear seat entertainment systems

关键特性

  • 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
