AR1020-I/SS

AR1020-I/SS

Touch Screen Controller IC, I2C, SPI Interface, 10 bit Resolution, 3.135 V to 3.465 V, SSOP-20

The AR1020-I/SS is an analog resistive Touch Screen Controller that features a complete, easy integration and universal touch screen controller chip. The AR1000 series has sophisticated proprietary touch screen decoding algorithms to process all touch data, saving the host from the processing overhead. It is providing filtering capabilities beyond that of other low-cost devices, the AR1000 delivers reliable, validated, and calibrated touch coordinates. Using the onboard EEPROM, the AR1000 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.

  • Power-saving sleep mode
  • Built-in drift compensation algorithm
  • 128-byte of user EEPROM
  • Off, stream, down, up to touch modes
  • 4, 5, and 8-wire analog resistive touch sensor
  • 10-bit Maximum touch resolution
  • 140 reports per second (typical) with a touch sensor of 0.02uF with 200R layers
  • The actual report rate is dependent on the touch sensor used

Applications:
Industrial, Communications & Networking, Consumer Electronics, Portable Devices
