Description
The MCP23S17-E/SO is an Electronic Component Model that belongs to the category of I/O Expanders. It is a device that offers 16-bit, general-purpose parallel I/O expansion for I2C bus or SPI applications. The MCP23S17-E/SO 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 device comes in two variations, the MCP23017 with an I2C interface, and the MCP23S17 with an SPI interface.
