SPI/I<sup>2</sup>C Bus Lines Control Multiple Peripherals
This application note compares two common serial, digital interfaces used by most analog ICs: SPI or 3-wire, and I2C or 2-wire. Each serial interface offers advantages or disadvantages for many designs, depending on criteria such as needed data rate, space availability, and noise considerations. This application note discusses the differences between these two serial interfaces and presents examples to demonstrate each interface in detail.
