Developing technologies for automotive communication gateway SoCs

27-02-2023 | Renesas | Semiconductors

Renesas Electronics Corporation has announced that it has developed four technologies for SoC devices for in-vehicle communication gateways. These SoCs are expected to define automotive systems' next-generation electrical/electronic (E/E) architecture.

SoCs for automotive gateways must deliver high performance to implement new applications such as cloud services and low power consumption when not in use. They also must deliver fast CAN response to support instant start-up. Also, these SoCs must provide power-efficient communication technology that facilitates network functions as a gateway utilising limited power and security technology to allow safe communication outside the vehicle. To meet these requirements, the company has developed an architecture that dynamically changes the circuit operation timing to match the vehicle conditions with optimised performance and power consumption; fast start-up technology by partitioning and powering essential programs only; a network accelerator that attains a power efficiency of 10Gbps/W; and security technology that stops communication interference by identifying and protecting vital in-vehicle communication related to vehicle control.

These technologies have been included in the company's R-Car S4 vehicle communication gateway SoC. With the latest R-Car S4, developers can speed up advances in E/E architectures, implement secure connection with cloud services, and provide safe and reliable vehicle control simultaneously.
