Microchip公司的MTCH6303是电容触摸屏控制器,提供多触摸协同和多手指表面手势,现代用户(UI)元件如收缩和放大,多手指滚动和划屏等嵌入设计,支持八吋电容触摸屏,主要用在传感器,工业,医疗电子,家庭和办公自动化和消费类电子产品.本文介绍了MTCH6303主要特性,框图,典型应用电路,以及MTCH6303多触摸电容触摸屏开发板DV102013主要特性和电路图.

Microchip’s MTCH6303 is an innovative turnkey projected capacitive touch controller that provides multi-touch coordinatesas well as a readymade multi-finger surface gesture suite. MTCH6303 brings modern user interface (UI) elements – such aspinch 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 tenfingers, typically at 100 Hz each for five touches. It also combines with Microchip’s MTCH652 High-voltage Line Driverto achieve a superior signal-to-noise ratio (SNR) for outstanding touch performance in noisy environments. 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 variousconsumer applications including exercise equipment and audio systems.

MTCH6303主要特性:

• Multi-Touch up to Ten Touches
• Five Touches Typically at 100 Hz+ Each
• 27RX x 19TX Channels Support Approximately 8"Touch Screens (larger possible)
• Combines with MTCH652 High-Voltage Driver forSuperior Signal-to-Noise Ratio (SNR)
