The MCP23S17 chip by Microchip is designed to add additional I/O pins to your microcontroller or single board computer. Unlike a 3 – 8 decoder or a Shift Register, these I/O Expanders use a data protocol (SPI) to communicate with the host – meaning these chips are a lot more flexible, each pin can be used as an input or output, and multiple chips can be used on a single bus!

Description
The MCP23S17 chip by Microchip is designed to add additional I/O pins to your microcontroller or single board computer. Unlike a 3 – 8 decoder or a Shift Register, these I/O Expanders use a data protocol (SPI) to communicate with the host – meaning these chips are a lot more flexible, each pin can be used as an input or output, and multiple chips can be used on a single bus!
Each chip adds 16 additional digital I/O lines, and with 3 configurable address pins, 8 of these chips can be placed on a single SPI bus. That means up to 128 digital inputs or outputs can be added per SPI bus! The chip is both 5V and 3.3V logic compatible meaning it will work with popular platforms like the Arduino or Raspberry Pi.
The MCP23S17 Class for Arduino ( http://playground.arduino.cc/Main/MCP23S17 ) is very easy to work with!
Features
- Up to 8 chips on one SPI bus
- 3.3V and 5V compatible
