MCP23018T-E/MJ Frequently Asked Questions (FAQs)

  • The maximum frequency of the I2C clock is 400 kHz, but it can be operated at 100 kHz or 400 kHz depending on the application.
  • The MCP23018 has three I/O configuration registers (IODIRA, IODIRB) that allow you to configure each pin as an input or output. A '1' in the register sets the pin as an input, while a '0' sets it as an output.
  • The INTA and INTB pins are interrupt output pins that can be used to notify the microcontroller of changes on the input pins. They can be configured to trigger on rising, falling, or both edges.
  • The MCP23018 can be reset by holding the SCL clock line low for a minimum of 4.7 ms. This resets the device to its power-on state.
  • The maximum current that can be sourced or sunk by the I/O pins is 25 mA. However, the total current sourced or sunk by all I/O pins should not exceed 125 mA.
