Part of the Hardware glossary: In a computer, a serial peripheral interface (SPI) is an interface that enables the serial (one bit at a time) exchange of data between two devices, one called a master and the other called a slave. An SPI operates in full duplex mode. This means that data can be transferred in both directions at the same time. The SPI is most often employed in systems for communication between the central processing unit (CPU) and peripheral devices. It is also possible to connect two microprocessors by means of SPI.
