Microchip has added to its touch control offering with the first resistive touch-screen controllers in its mTouch range, which already includes capacitive and inductive touch-sensing devices.

Designing in resistive-touch user interfaces usually meant you were limited to basic ADCs and signficant circuit design.

According to Microchip, the AR1000 controller can eliminate this design work by providing proprietary touch-screen decoding algorithms that enable applications to receive fully processed, reliable touch coordinates.

The AR1000 controllers provide universal 4-, 5- and 8-wire support, as well as support for SPI, I2CTM and UART communication interfaces and are available in 20-pin QFN, SOIC and SSOP packages.

There is also the mTouch AR1000 development kit (part # DV102011), which includes the AR1000 development board, a 7 inch four-wire resistive overlay, a PICkit Serial Analyzer and all necessary interface cables, as well as a CD containing technical documentation, GUI and all necessary software.
