MCP23018-E/SO Frequently Asked Questions (FAQ)
-
The maximum frequency of the I2C clock is 400 kHz.
-
The MCP23018 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 MCP23018 is 5V tolerant, but it operates at 1.8V to 5.5V, so a level shifter may be required for 5V systems.
-
The IODIRA and IODIRB registers are used to configure the direction of the GPIO pins. A '1' sets the pin as an input, and a '0' sets the pin as an output.
