MCP23S17-E/ML Frequently Asked Questions (FAQs)

  • The maximum frequency of the SPI interface is 10 MHz.
  • You can use the CS (Chip Select) pin to select which device to communicate with. Each device should have a unique CS pin connection.
  • The RESET pin is used to reset the device to its default state. It can be tied to VDD or driven by an external reset signal.
  • Yes, you can use a bit-bang SPI implementation or a software SPI library to communicate with the MCP23S17, even if your microcontroller doesn't have a built-in SPI peripheral.
  • The interrupt pins can be configured to trigger on rising, falling, or both edges of the input signals. This is done by setting the corresponding bits in the IOCON register.
