Microchip’s MTCH6303 is an innovative turnkey projected capacitive touch controller that provides multi-touch coordinates as well as a readymade multi-finger surface gesture suite. MTCH6303 brings modern user interface (UI) elements – such as pinch and zoom, multi-finger scrolling, and swipes – to any embedded design, with minimal host requirements.
The MTCH6303’s advanced signal processing provides noise-avoidance techniques and predictive tracking for ten fingers, typically at 100 Hz each for five touches. It also combines with Microchip’s MTCH652 High-voltage Line Driver to achieve a superior signal-to-noise ratio (SNR) for outstanding touch performance in noisy environments (refer to www.microchip.com/MTCH652). These capabilities are critical in demanding environments such as industrial controls, home and office automation with security control panels, thermostat, printers and lighting controls, and various consumer applications including exercise equipment and audio systems.
