MCP23S09-E/SO Frequently Asked Questions (FAQ)
-
The maximum frequency of the SPI interface is 10 MHz.
-
You can use the CS (Chip Select) pin to select which device to communicate with. Each device should have a unique CS pin connection.
-
The RESET pin is used to reset the device to its default state. It can be tied to VDD or driven by an external reset signal.
-
Yes, but you'll need to use a SPI-to-other-bus bridge chip or a microcontroller with a built-in SPI-to-other-bus bridge.
-
You can configure the MCP23S09 for input or output mode by writing to the IODIR register. A '1' sets the pin as an input, and a '0' sets the pin as an output.
