Description and Features

The MIPI SoundWire is an interface specification that enables bidirectional digital audio communication between a master and one or more slave devices, or among only slave devices. It is optimized for mobile and ‘mobile-inspired’ systems. It can coexist with MIPI-compliant and non MIPI-compliant devices alike. MIPI SoundWire is low-complex, low-power, and low-latency interface that supports multi-channel data. Being low gate count allows it to be incorporated it into smaller components, like microphones and amplifiers. SoundWire Master is used in master controllers like amplifiers or processors, transferring or receiving audio data from a SoundWire slave, like the one connected to a microphone or a speaker. Similarly, SoundWire Slave is a SoundWire standard-compliant slave, supporting slave to slave communication, depending on the device component connected.
