MCP23S18-E/SO Frequently Asked Questions (FAQ)

  • 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 SPI-to-I2C bridge chip or a microcontroller with an I2C interface to communicate with the MCP23S18.

  • The interrupt pins can be configured as active-high or active-low, and can be triggered by specific events such as input changes or output matches.
