Integrated controllers simplify resistive touch screen control devices
Microchip has launched what it describes as 'the embedded industry's most innovative' analogue resistive touch screen controllers.
The mTouch AR1000 provides built in decoding and advanced filtering, as well as controller driven calibration.
The controller has been introduced to address the fact that embedded systems implementing resistive touch user interfaces have been limited to basic ADCs that required extensive development and integration. Microchip says that the AR1000 controllers eliminate this type of trial and error engineering by providing proprietary touch screen decoding algorithms, enabling applications to receive fully processed touch coordinates.
It has been designed for applications such as mobile phones, industrial automation, retail point of sale, gaming / entertainment, and automobile navigation systems.
The AR1000 controllers provide universal 4-, 5- and 8-wire support, as well as support for SPI, I2C and UART communication interfaces and are available in 20-pin QFN, SOIC and SSOP packages.
