Regardless of the partitioning, the AURIX™ automotive microcontroller as a gateway provides the necessary physical isolation and protocol translation to safely route messages between the different functional domains. The processor subsystem consists of a single microcontroller, multiple microcontrollers, or a microcontroller/microprocessor combination depending on overall system partitioning and performance requirements. Depending on the overall current consumption and connectivity requirements, this subsystem can be realized using integrated solutions ( System Basis Chips, SBCs) or discrete components. The power supply subsystem feeds power to the processors, communication interfaces, and various circuits on the PCB.
