The STMicroelectronics SPI to isolated SPI dongle allows converting SPI signals in isolated SPI signals, thereby reducing the number of necessary wires from 4 to 2. As the ISOSPI signals can travel for several meters, this protocol is particularly suitable for automotive high voltage applications where electrical isolation is required by the safety standards and the cable length can affect the communication among devices located in distant parts of the vehicle.
