June 30, 2015 - Microchip announces MTCH6303 touch screen controller that provides advanced multi-touch and gesture solution for touch screens up to 10”. The MTCH6303 provides multi-touch coordinates as well as a readymade multi-finger surface gesture suite that 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 signal processing provides noise-avoidance techniques and predictive tracking for 10 fingers, at scan rates of up to 250 Hz with a minimum of 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.
When combined with the MGC3130, the MTCH6303 solution is capable of supporting 3D air gestures up to 20 cm distance from the touch panel. Microchip’s MGC3130 E-field-based 3D tracking and gesture controller includes Microchip’s GestIC technology, allowing user input via natural hand and finger movements in free space. This combination empowers designers to create interface-control possibilities in two and three dimensions that differentiate their products from the competition.
The advanced capabilities of the MTCH6303 create robust, ready-to-go touch and gesture solutions for the rapid growth of human-interface applications and requirements in the industrial (e.g., machine control panels, HVAC controls, metering and test equipment), home-automation (e.g., security control panels, thermostat and lighting controls) and office-equipment (e.g., printers, copiers and fax machines) markets, among others.
The MTCH6303 is supported by Microchip’s Multi-Touch Projected Capacitive Touch Screen Development kit, which is available with free, downloadable software. The DV102013 incorporates the MTCH6303 projected-capacitive touch controller and the MTCH652 high-voltage driver on a controller board, and includes a transparent, 8” ITO touch panel for easy demonstration of the MTCH6303’s touch-controller capabilities and supporting graphical user interface (GUI) functionality.
Microchip’s free MTCH6303 GUI provides designers with complete access to the configuration and tuning parameters. Advanced visualization windows assist all user levels with easy-to-comprehend feedback, to accelerate design integration for fast time-to-market.
Additionally, Microchip empowers designers by providing access to the firmware library, to enable further customizations for maximum design flexibility and control.
