Motorola invented the SPI (Serial Peripheral Interface) serial Bus to be able that microcontroller could be connected with peripheral devices or even that microcontroller could be connected to each other. As for I2C the SPI bus is based on the master-slave principle but the achievable data rate is much higher and can be in the Mhz range. The SPI is established as a standard since many years and is used in a wide spectrum of devices. For example manufacturers of DAC converters, memories, sensors, RTCs, USB controllers and many more are using the SPI technology.
Total Phase offers powerful, compact and inexpensive SPI host Adapter for programming, erasing and verifying serial SPI memory chips and SPI protocol analyzers to support the developer during the debug phase.
