The Microsecond Bus, μSB or MSB is an asymmetric serial communication interface specification for short-distance communication between a master and multiple slaves. The MSB has been developed in the first place for motor management applications in order to reduce the classical pulse-width modulation (PWM) of power loads by a fast serial interface with low pin count and low latency for the downstream to the smart power device. The downstream from master to slave is synchronous with low latency, while the upstream, mainly used to send diagnostic information from the slave back to the master is asynchronous, and can be slower.
The name of the bus originates from the time of one microsecond to transmit 16 bits in one of the first implementations. The bus was developed by Infineon and published in SAE International in 2005.[1] In the meantime the bus has been adopted by several other automotive semiconductor providers.
