Device Overview

Summary

In Production
The ATMXT449T-A Automotive touchscreen controller is aimed at display sizes up to 8” used in center stacks, navigation systems or rear seat entertainment systems. This family of automotive touchscreen controller brings Microchip’s unmatched Adaptive Sensing technology to the Automotive market. It enables 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 and glove touch. Adaptive Sensing is also resistant to water and moisture and ensures superior touch performance even in these harsh conditions.
