AR1021 - Resistive Touch Screen Controller

Download the AR1021 datasheet PDF. This datasheet also covers the AR1010 variant, as both devices belong to the same resistive touch screen controller family and are provided as variant models within a single manufacturer datasheet.

Features

  • RoHS Compliant.
  • Power-Saving Sleep mode.
  • Industrial Temperature Range.
  • Built-in Drift Compensation Algorithm.
  • 128 Bytes of User EEPROM Power Requirements.
  • Operating Voltage: 2.5-5.0V ±5%.
  • Standby Current: - 5V: 85 µA, typical; 125 µA (maximum) - 2.5V: 40 µA, typical; 60 µA (maximum).
  • Operating “No touch” Current: - 3.0 mA (typical).
  • Operating “Touch” Current: - 17 mA, typical, with a touch sensor having 200 layers.
