ATMXT640U数据手册集成电路（IC）的触摸屏控制器规格书PDF

描述 Description

In ProductionThe ATMXT640U touchscreen controller is aimed at display sizes up to 8.2” used in Industrial designs. This brand new family of touchscreen controller brings Microchip’s unmatched Adaptive Sensing technology to the Industrial market. It enables dynamic touch classification, a feature that automatically and intelligently switches between self-capacitance and mutual-capacitance sensing to provide users a seamless transition between a finger touch and glove touch. Adaptive Sensing is also highly resistant to moisture.  Proprietary differential touch sensing delivers unparalleled noise immunity ensuring superior touch performance even in harsh environments.

简介

ATMXT640U属于集成电路（IC）的触摸屏控制器。由制造生产的ATMXT640U触摸屏控制器触摸屏控制器是一种集成电路，可在触摸屏传感器阵列与屏幕操作的设备之间提供接口。该控制器从传感器阵列（通常是电阻式或电容式）接收位置信息。然后，位置信息又通过串行、并行、USB 或 UART 接口传递给微控制器。
