MCP23008-E/P Frequently Asked Questions (FAQs)

  • The maximum frequency of the I2C clock is 400 kHz.
  • The MCP23008 can be reset by pulling the RESET pin low for a minimum of 1 ms.
  • The INTA and INTB pins are interrupt output pins that can be used to notify the microcontroller of changes in the input port states.
  • Yes, the MCP23008 is 5V tolerant, but it operates at 2.7V to 5.5V. If your microcontroller operates at 5V, you may need to use level shifters or voltage dividers to interface with the MCP23008.
  • The MCP23008 can be configured for input or output mode by writing to the IODIRA and IODIRB registers. A '1' in the register sets the corresponding pin as an input, while a '0' sets it as an output.
