16-bit I/O Port Expander MCP23S17 (SPI)

The MCP23S17 provides 16-bit, general purpose parallel I/O expansion for SPI applications.

The 16-bit I/O port functionally consists of two 8-bit ports (PORTA and PORTB). The MCP23S17 can be configured to operate in 8-bit or 16-bit modes

We also have the I2C version of this chip here MCP23017
