MCP23S18-E/MJ Frequently Asked Questions (FAQ)

  • The maximum frequency of the SPI interface is 10 MHz.

  • To configure the MCP23S18 as an output port, set the IODIR register to 0x00. This sets all pins as outputs.

  • The INTA and INTB pins are interrupt output pins that can be used to signal an interrupt to the microcontroller when a change is detected on the input pins.

  • The MCP23S18 can be reset by pulling the RESET pin low for a minimum of 1 ms.

  • Each I/O pin can source or sink up to 25 mA of current.
