MCP23S08-E/ML Frequently Asked Questions (FAQ)

  • The maximum frequency of the I2C clock is 400 kHz, as per the I2C specification.

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

  • The RESET pin is an active-low input that resets the device when pulled low. It can be used to reset the device to its default state.

  • Yes, you can use the MCP23S08 with a microcontroller that doesn't have I2C by using a bit-banging approach, where the microcontroller generates the I2C clock and data signals manually.

  • The interrupt pins can be configured to trigger on rising, falling, or both edges of the input signals. This is done by setting the corresponding bits in the IOCON register.
