FlexEnable Atmel Launches Self/Mutual Capacitance Automotive-qualified Touchscreen Controllers For Up to 10″ Touchscreens

Atmel Corporation, a microcontroller (MCU) and touch technology solutions provider, today announced the company has expanded its portfolio of automotive-qualified maXTouch (R) touchscreen controllers with the mXT641T family. The new family is optimized for capacitive touchpads and touchscreens from 5 to 10 inches. These mXT641T devices are the industry’s first auto-qualified self- and mutual-capacitance controllers meeting the AEC-Q100 standards for high reliability in harsh environments.

The automotive-qualified maXTouch mXT641T family incorporates Atmel’s Adaptive Sensing technology to enable dynamic touch classification, a feature that automatically and intelligently switches between self- and mutual-capacitance sensing to provide users a seamless transition between a finger touch, hover, or glove touch. It eliminates the need for users to manually enable “glove mode” in the operating system to differentiate between hover and glove modes. Adaptive Sensing is also resistant to water and moisture and ensures superior touch performance even in these harsh conditions.

The new devices support stringent automotive requirements including hover and glove support in moist and cold environments, thick lens for better impact resistance, and single-layer shieldless sensor designs in automotive center consoles, navigation systems, radio interfaces and rear-seat entertainment systems. The single-layer shieldless sensor design eliminates additional screen layers, delivering better light transparency resulting in lower power consumption along with an overall lower system cost for the manufacturer.

“More consumers are demanding high-performance touchscreens in their vehicles with capacitive touch technology,” said Rob Valiton, Senior Vice President and General Manager, Automotive, Memory and Secure Products Business Units. “Atmel is continuing to drive more innovative, next-generation touch technologies to the automotive market and our new family of automotive-qualified maXTouch T controllers is further testament to our leadership in this space. Atmel is the only automotive-qualified touch supplier with over two decades of experience in designing, developing, and manufacturing semiconductor solutions that meet the stringent quality and reliability standards for our automotive customers.”
