TT7004V is an automotive grade capacitive touchscreen controller with sensing and processing technology to resolve locations and report positions of up to ten fingers on a touchscreen. This touchscreen controller converts an array of sensor capacitances into an array of digital values that are processed by touch-detection and position-resolution algorithms within the controller.
