ATmXT225T数据手册开发板套件编程器的评估演示板及套件规格书PDF

描述 Description

In ProductionThe ATMXT225T-A Automotive touchscreen controller is aimed typically at touchpads and display sizes up to 5”. 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.
In addition, the ATMXT225T-A supports Hover operation, which tracks the position of the finger when it floats within 20mm of the touchscreen. Hover allows user interaction without making a physical contact, and brings a more dynamic interface to user applications.
