Touch Screen Controller SMD 20-Pin SOIC Tube

The Microchip mTouchTM AR1021 Series Resistive Touch Screen Controller is a complete, easy to integrate, cost-effective and universal touch screen controller chip. The AR1021 Series has sophisticated proprietary touch screen decoding algorithms to process all touch data, saving the host from the processing overhead. Providing filtering capabilities beyond that of other low-cost devices, the AR1021 delivers reliable, validated, and calibrated touch coordinates. Using the on-board EEPROM, the AR1021 can store and independently apply the calibration to the touch coordinates before sending them to the host. This unique combination of features makes the AR1000 the most resource-efficient touch screen controller for system designs, including embedded system integrations.
