The interface was developed by Motorola in the mid-1980s and has become a de facto standard. Typical applications include Secure Digital … See more The SPI bus specifies four logic signals: • SCLK: Serial Clock (output from master) • MOSI: Master Out Slave In (data output from master) • MISO: Master In Slave Out (data output from slave) See more Advantages • Full duplex communication in the default version of this protocol • Push-pull drivers (as opposed to open drain) provide good signal integrity and high speed • Higher throughput than I²C or SMBus. Not limited to any maximum clock … See more The SPI bus is a de facto standard. However, the lack of a formal standard is reflected in a wide variety of protocol options. Different … See more Intelligent SPI controllers A Queued Serial Peripheral Interface (QSPI; see also Quad SPI) is a type of SPI controller that uses a data queue to transfer data across … See more The SPI bus can operate with a single master device and with one or more slave devices. If a single slave device is used, the SS pin may be fixed to logic low if the slave permits it. Some slaves require a falling edge of … See more The board real estate savings compared to a parallel I/O bus are significant, and have earned SPI a solid role in embedded systems.
