SPI

Serial Peripheral Interface - a synchronous serial communication protocol using four wires (MOSI, MISO, SCK, CS) for high-speed data transfer.

SPI

SPI (Serial Peripheral Interface) is a synchronous serial communication protocol for high-speed data transfer.

Definition

SPI uses four wires: MOSI (master out, slave in), MISO (master in, slave out), SCK (clock), and CS (chip select) for full-duplex communication. Operates at standard Voltage levels.

Key Points

  • Four-wire interface
  • Faster than I2C
  • Full-duplex communication
  • Common in displays and memory
