Automotive-qualified controller family

  • 24-Sep-2013 08:05 EDT

Atmel Corp.’s new maXTouch family enables single-layer shieldless designs in automotive center stacks, navigation systems, radio interfaces, or rear-seat entertainment systems. The mXT336S is optimized for 7-in touch screens, while the mXT224S targets smaller touch screens and touch pads. According to Atmel, the new AEC-Q100-compliant touch devices offer multitouch, faster response time, more precise touches, robust operation, and lower power consumption. In addition, the devices provide dedicated embedded functionality that meets current automotive design requirements. Dedicated firmware and a high signal-to-noise ratio make the mXT336S and mXT224S suitable for very noisy environments. Since only a high signal-to-noise ratio enables detection of touches with a “gloved” finger, the devices provide full support for gloved-hand operation on automotive touch screens, claims the company.
