描述 Description

In ProductionThe ATMXT641TD-A Automotive touchscreen controller is aimed at display sizes up to 9” 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.

In addition, the ATMXT641TD-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.

簡介

ATMXT641TD-A屬于集成電路（IC）的觸摸屏控制器。由制造生產(chǎn)的ATMXT641TD-A觸摸屏控制器觸摸屏控制器是一種集成電路，可在觸摸屏傳感器陣列與屏幕操作的設(shè)備之間提供接口。該控制器從傳感器陣列（通常是電阻式或電容式）接收位置信息。然后，位置信息又通過串行、并行、USB 或 UART 接口傳遞給微控制器。
