Description

The Microchip mTouch™ AR1000 Series Resistive Touch Screen Controller is a complete, easy to integrate, cost-effective and universal touch screen controller chip solution. The AR1000 Series has sophisticated proprietary touch screen decoding algorithms to fully process all touch data and save the host from this overhead. More than the usual "preprocessing" features of other low cost devices, the AR1000 delivers reliable, validated and calibrated touch coordinates. Using its onboard EEPROM, the AR1000 can store and independently apply the calibration to the touch coordinates before sending them to the host. This unique combination makes the AR1000 the most resource efficient touch screen controller for embedded designs. The AR1011 touch screen controller supports UART communication. Please reference the AR1021 touch screen controller for I2C™Compatible and SPI communication.
