High-speed data communication processing such as firewalls, predictive maintenance, and OTA
Improved computational performance with low-power real-time in-vehicle connectivity

STMicroelectronics has launched the Smart Gateway Platform (SGP) to provide development tools useful for prototyping automotive smart gateway and domain controller applications.

Recently, as automotive architectures are rapidly evolving, including in-vehicle networking and cloud connectivity with high-speed data transmission rates, the demand for high-performance smart gateways and domain controller ECUs is also increasing.
ST's modular smart gateway platform provides firewall functions and processing capable of handling predictive maintenance, over-the-air (OTA) upgrades, and high-speed data communication between different ECUs and the cloud, based on Gigabit Ethernet communication between secure ASIL B Telemaco 3P microprocessors and ASIL D SPC58/Chorus microcontrollers.

The Chorus MCU provides low-power in-vehicle connectivity in real time through multiple CAN FD interfaces, and the Telemaco 3P MPU enhances the gateway's computational performance by providing Arm Cortex A7 processing performance along with support for POSIX OS and an embedded security module that handles wireless updates, firewalls, and predictive maintenance functions.

The smart gateway platform reference design It not only supports LIN and FlexRay connections but is also equipped with various in-vehicle network interfaces, including multiple Ethernet and CAN ports. In addition, a starter package is provided, including hardware design files, hardware and software documentation, software utilities, and sample applications.

In addition, extended connectivity with Wi-Fi and LTE modules is integrated to enable the realization of perfect prototypes by applying cloud connectivity simulation. Since the modular architecture supports an optimal framework, the platform can be expanded based on performance, networking, and software.
