Application Scenarios & Design Considerations

4-Wire Touch Screen Controller with low voltage digital I/O

Alternative Part Number

  • ADS7846E --: Pin-compatible 4-wire resistive touchscreen controller from TI with similar SPI interface and functionality, widely used as a direct substitute.
  • XPT2046 --: Low-cost drop-in compatible 4-wire touchscreen controller with the same register set and SPI protocol, commonly used as a replacement for TSC2046.
  • ADS7843E --: Earlier TI 4-wire touchscreen controller in the same family with compatible SPI interface; suitable when full TSC2046 feature set is not required.
