Microchip’s Multi-touch Projected Capacitive Touch Screen Development Kit enables the creation of advanced touch interface solutions using MTCH6303 with up to 18V boost via the MTCH652 device.
USB Stack
Sensor Configuration/Calibration
The MTCH6303 solution brings advanced features, including noise robustness, larger sensor size support up to 8", faster scanning speeds and the ability to combine with the high-voltage driver, MTCH652, to achieve superior signal to noise ratio. These capabilities enable a wider range of designs, including transparent touch screens over displays with advanced multi-touch gestures for a rich user interface.
