MCP23017-E/SP Frequently Asked Questions (FAQs)

  • The maximum frequency of the I2C clock is 400 kHz.
  • The MCP23017 can be reset by pulling the RESET pin low for at least 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 MCP23017 is 5V tolerant, but it requires a 3.3V power supply. You can use level shifters or voltage dividers to interface with a 5V microcontroller.
  • The IODIRA and IODIRB registers are used to configure the direction of the GPIO pins. A '1' in the register sets the pin as an input, while a '0' sets it as an output.
