Prior to the AR1000 controller, embedded systems implementing resistive-touch user interfaces were limited to basic Analog-to-Digital Converters (ADCs) that required extensive development and integration. The AR1000 controllers eliminate this type of trial-and-error engineering by providing sophisticated, proprietary touch-screen decoding algorithms that enable applications to receive fully processed, reliable touch coordinates. Combining Microchip’s capabilities in microcontroller manufacturing with the recently acquired Hampshire Company’s 15+ years of experience designing resistive touch-screen controllers, the AR1000 controllers enable low-risk product development, lower total system cost and shorter time to market for embedded resistive-touch designs. Popular due to its low cost, acceptance of finger, glove or stylus-pen inputs, and overall ease of manufacturing and integration, resistive touch-sensing technology is suitable for applications such as mobile phones, industrial automation, retail point-of-sale, gaming/entertainment, and automobile navigation systems.
“The AR1000 controllers give designers the flexibility they need to quickly and easily implement analog resistive touch-screen interfaces,” said Steve Drehobl, vice president of Microchip’s Security, Microcontroller and Technology Development Division. “The controllers meet the needs of today’s touch solutions with low cost and reduced development time, while delivering the Microchip brand promises of quality, reliability and performance.”
The AR1000 controllers provide universal 4-, 5- and 8-wire support, as well as support for SPI, I2C™ and UART communication interfaces. They are well suited for resistive-touch designs in the consumer (mobile communication devices, Personal Digital Assistants, Global Positioning Systems, media players, printers), medical (patient-monitoring equipment), industrial (kiosks, touch-screen monitors, portable instruments, point-of-sale terminals), and automotive markets (navigation systems), among others.
Development Support
Microchip also announced the mTouch AR1000 Development Kit (part # DV102011) today, which provides everything designers need to get started using AR1000 controllers. The kit includes the AR1000 development board, a 7” four-wire resistive touch screen, a PICkit™ Serial Analyzer and all necessary interface cables, as well as a CD containing technical documentation and all necessary software. The CD also includes an easy-to-use AR1000 configuration utility, which has a Graphical User Interface (GUI) that enables designers to test all user-configurable options with the AR1000 controllers. The kit is priced at $99.99 and can be ordered today, at http://www.microchipdirect.com.
For additional design support, Microchip offers an online Touch-Sensing Solutions Design Center ( http://www.microchip.com/mtouch). This comprehensive Web sites provides a wide range of technical tools and resources that designers can use for developing capacitive, inductive and resistive touch-sensing applications—all in one, convenient location.
