Infineon Technologies PSOC™ Automotive multitouch

CYAT8168X is a capacitive touchscreen controller with the sensing and processing technology to resolve the locations and report the positions of up to ten fingers on the touchscreen. The touchscreen controller converts an array of sensor capacitances into an array of digital values, which are processed by touch-detection and position-resolution algorithms in the controller. These algorithms determine the location and signal magnitude of each finger on the touchscreen.
