Analog Resistive Touch-Screen Controllers for Embedded Markets Announced by Microchip Technology
Universal Touch-Screen Controllers Provide Fully Processed, Reliable Touch Coordinates for a Variety of Consumer, Industrial and Medical Applications
CHANDLER, Ariz.--(BUSINESS WIRE)--Microchip Technology Inc. (NASDAQ: MCHP), a leading provider of microcontroller and analog semiconductors, today announced the mTouch™ AR1000 Resistive Touch-Screen Controllers—the embedded industry’s most innovative analog resistive touch-screen controllers. Adding to Microchip’s comprehensive portfolio of mTouch capacitive and inductive touch-sensing solutions, the AR1000 controllers further solidify Microchip’s position of having the broadest touch-controller product offering in the semiconductor industry. By providing built-in decoding and advanced filtering, as well as controller-driven calibration, the controllers lower costs and reduce time to market for any embedded resistive-touch design.
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.
