MCP23018-E/SSVAO Frequently Asked Questions (FAQ)

  • The maximum frequency of the I2C clock is 1.7 MHz for standard mode and 3.4 MHz for fast mode.

  • You can use the three address pins (A0, A1, and A2) to set a unique address for each device, allowing up to 8 devices on the same bus.

  • The reset pin (RESET) is an active-low input that resets the device to its default state when pulled low. It can be used to initialize the device or recover from a fault condition.

  • Yes, you can use the MCP23018 as an output expander only by not using the input pins and configuring the device as an output-only device.

  • The MCP23018 has an interrupt output (INT) that can be connected to a microcontroller's interrupt input. The interrupt is triggered when a change is detected on any of the input pins. You can then read the interrupt capture register to determine which pin triggered the interrupt.
