Microchip launches mTouch AR1000, an analog resistive touch screen controller for the embedded market
Microchip Technology Inc. announced that it has launched the mTouch AR1000 controller, the most innovative analog resistive touch screen controller in the embedded industry. The AR1000 controller complements Microchip's comprehensive mTouch capacitive and inductive touch sensing solution portfolio, further consolidating Microchip's position as the most extensive supplier of touch controller products in the semiconductor industry. By providing built-in decoding and advanced filtering, as well as controller-driven calibration, the AR1000 controller reduces the cost of any embedded resistive touch design and speeds time to market.
Before the AR1000 controller was introduced, embedded systems that implemented resistive touch user interfaces were limited to basic analog-to-digital converters (ADCs) and required large-scale development and integration. The AR1000 controller eliminates this type of trial-and-error engineering by providing advanced proprietary touch-screen decoding algorithms, allowing applications to get reliable touch coordinates that are fully processed. The AR1000 controller combines Microchip's excellent microcontroller manufacturing capabilities with the recently acquired Hampshire company's more than 15 years of experience in designing resistive touch screen controllers, which reduces the risk of product development and total system cost for embedded resistive touch design. And shorten time to market. Due to the low cost, the ability to use fingers, input through gloves or stylus, and overall ease of manufacturing and integration, resistive touch technology is very popular, suitable applications include mobile phones, industrial automation, retail point of sale terminals, gaming / entertainment facilities And car navigation system.
Steve Drehobl, vice president of security, microcontroller and technology development at Microchip, said: "The AR1000 controller gives designers the flexibility they need to quickly and easily implement an analog resistive touch screen interface. The controller is less expensive and shorter The development time meets the various needs of today's touch solutions, and also reflects Microchip's brand commitment to quality, reliability and performance. "
The AR1000 controller has universal 4-wire, 5-wire, and 8-wire support, and supports SPI, I2C, and UART communication interfaces. The product is very suitable for resistive touch design, such as consumer (mobile communication devices, personal digital assistants, global positioning systems, media players and printers), medical (patient monitoring equipment), industry (self-service kiosks, touch screen displays, portable Instruments and point-of-sale terminals) and the automotive market (navigation systems), etc.
Development tool support
Microchip also introduced the mTouch AR1000 development kit (part number: DV102011) to meet all the needs of designers using AR1000 controllers. The kit includes an AR1000 development board, a 7-inch 4-wire resistive touch screen, a PICkit serial analyzer and all necessary interface cables, as well as a CD containing relevant technical documents and all necessary software. The CD also includes an easy-to-use AR1000 configuration utility. Through the graphical user interface (GUI) of the program, designers can use the AR1000 controller to test all user-configurable options. Tool kits can now be ordered through http: //.
