The evolution of automotive architectures to include high throughput in-vehicle networking and high data-rate connectivity to the cloud has increased demand for high-performance Smart-Gateway and Domain-Controller Electronic Control Units (ECUs).

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

While the Chorus MCU provides real-time, low-power, and secure in-vehicle connectivity through its multiple CAN-FD interfaces, the Telemaco3P MPU extends gateway computational capabilities by delivering dual Arm® Cortex® A7 processing power with the Posix OS support and embedded Security Module to handle OTA updates, firewall, and predictive-maintenance functions.

The SGP reference design features a rich set of in-vehicle network interfaces including multiple Ethernet and CAN ports as well as support for LIN and FlexRay connections. It is deployed with a comprehensive starter package including hardware design files, hardware/software documentation, software utilities (drivers and flashers), and sample applications.

The SGP also integrates expansion connections to Wi-Fi and LTE modules for full prototyping of use cases requiring cloud-connectivity simulation. Its modular architecture provides an optimal framework for easy platform scalability in performance, networking, and software.
