MICROCHIPAR1021-I/SOAR1021-I/SO, Resistive Touch Screen Controller, 10 bit I2C, SPI 4-Wire, 5-Wire, 8-Wire, 20-Pin SOIC

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.

Additional Features: Supports any manufacturer's 4-, 5-, or 8-wire analog resistive touch screen I2C or SPI communication

1024x1024 resolution

EEPROM calibration retention

Supports any size analog resistive touch screen, 1.5" - 24"
