ST’s modular Smart-Gateway Platform (SGP) has been built on gigabit Ethernet communication between the secure and ASIL-B Telemaco3P MPU and the ASIL-D SPC58/Chorus MCU. The platform provides powerful processing capability for firewall functionalities, predictive maintenance, OTA upgrades, and high data-rate communication between different ECUs and to the cloud.

The Chorus MCU offers real-time, low-power, and secure in-vehicle connectivity through multiple CAN-FD interfaces, and the Telemaco3P MPU delivers dual Arm Cortex A7 processing power with Posix OS support and embedded Security Module for OTA updates, firewall, and predictive-maintenance functions.

The SGP reference design has a full set of in-vehicle network interfaces including multiple Ethernet and CAN ports as well as LIN and FlexRay support. The SGP also integrates expansion connections for Wi-Fi and LTE modules.It comes with a comprehensive starter package including hardware design files, hardware/software documentation, software utilities (drivers and flashers), and sample applications.
