Description

MCP23S17 I/O Expander IC with SPI Interface

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

The MCP23S17 I/O Expander IC consists of multiple 8-bit configuration registers for input, output and polarity selection. The system master can enable the I/Os as either inputs or outputs by writing the I/O configuration bits (IODIRA/B). The data for each input or output is kept in the corresponding input or output register. The polarity of the Input Port register can be inverted with the Polarity Inversion register. All registers can be read by the system master.
