The 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.
Support: off the shelf maXTouch standard modules are available
to help shorten development time and reduce risk. Microchip also has a strong
selection of factory trained global touch sensor module partners to help
support custom touch sensor and/or touchscreen display designs.
