Microchip (AR1020-I/SS) Touch Screen Controller IC, I2C, SPI Interface

Touch Screen Controller IC, I2C, SPI Interface, 10 bit Resolution, 3.135 V to3.465 V, SSOP-20Product OverviewThe AR1020-I/SS is an analogue resistive Touch Screen Controller featurescomplete, easy to integrate and universal touch screen controller chip. TheAR1000 series has sophisticated proprietary touch screen decoding algorithms toprocess all touch data, saving the host from the processing overhead. It isproviding filtering capabilities beyond that of other low-cost devices, theAR1000 delivers reliable, validated and calibrated touch coordinates. Using theon-board EEPROM, the AR1000 can store and independently apply the calibration tothe touch coordinates before sending them to the host. This unique combinationof features makes the AR1000 the most resource-efficient touch screen controllerfor system designs, including embedded system integrations.Power-saving sleep modeBuilt-in drift compensation algorithm128-byte of user EEPROMOff, stream, down, up touch modes4, 5 and 8-wire analogue resistive touch sensor10-bit Maximum touch resolution140 reports per second (typical) with a touch sensor of 0.02uF with 200R layersActual report rate is dependent on the touch sensor usedApplicationsIndustrial, Communications & Networking, Consumer Electronics, Portable DevicesProduct InformationIC Interface Type: I2C, SPIResolution (Bits): 10bitSupply Voltage Min: 3.135VSupply Voltage Max: 3.465VController IC Case Style: SSOPNo. of Pins: 20PinsProduct Range: AR1000MSL: MSL 1 - Unlimited
