A gateway controller serves as a communication bridge between the various networks inside the vehicle, including but not limited to CAN (low, high speed), LIN, ISO-9141 and J1850. The electronics may reside in a stand alone module or may be embedded in another application, such as a smart junction box, body controller, or instrument cluster. ST, with a broad portfolio of BCD, CMOS and power technologies, can provide a complete gateway solution, including bus transceivers, regulators and low cost, high performance microcontrollers with network protocol handlers’ on-chip. A sampling of ST products that are applicable to gateway applications can be found in the following block diagram.
