    Hi Sean,

    The MCP23S08T is the SPI controlled IO expander while the MCP23008 is the I2C controlled IO expander.

    Our team does not have a SPI controlled IO expander, but we do offer I2C controlled IO expanders. 

    Here is a list of our 3.3V IO expanders of our newest silicon. 

    If the customer has a 5V application, consider the TCA version instead of the TCAL version. 

    i.e.

    TCAL6416 is 3.3V

    TCA6416 is 5.0V

    Regards,

    Tyler
