Microchip Technology recently announced a new addition to its Human Interface Solutions portfolio. The MTCH6303 is a turnkey projected-capacitive touch controller for touch pads and screens. Touch sensors with up to 1,000 nodes and diagonals of up to 10” are supported. The MTCH6303 provides multi-touch coordinates as well as a ready-made multi-finger surface gesture suite that brings modern user interface (UI) elements (e.g., 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 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 can support 3-D air gestures up to 20 cm from the touch panel. Microchip’s MGC3130 E-field-based 3-D tracking and gesture controller includes Microchip’s GestIC technology, allowing user input via natural hand and finger movements in free space. Thus, you can create interface-control possibilities in two and three dimensions.
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), home automation (e.g., lighting controls) and office equipment (e.g., printers) markets, among others.
The MTCH6303 is supported by Microchip’s new $149 Multi-Touch Projected Capacitive Touch Screen Development Kit (part # DV102013), which is now 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 you 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.
The new MTCH6303 is available today in 64-pin QFN and TQFP packages, for sampling and volume production. Pricing starts at $2.46 each, in 10,000-unit quantities.
The MTCH652 is available today in 28-pin QFN, SOIC and SSOP packages, for sampling and volume production. Pricing starts at $1.04 each, in 10,000-unit quantities. The MGC3130 is available in a 28-pin QFN package for sampling and volume production. Pricing starts at $2.26 each in 10,000-unit quantities.
