Industry’s highest bandwidth switch solution enables efficient zonal and central compute platforms and accelerates adoption of software defined vehicles

SAN JOSE, Calif., May 23, 2022 (GLOBE NEWSWIRE) -- Broadcom Inc. today announced it has delivered its high bandwidth monolithic automotive Ethernet switch device, the BCM8958X, designed to address the growing bandwidth need for in-vehicle networking applications and facilitate the adoption of software defined vehicles (SDV). The BCM8958X features 16 Ethernet ports of which up to six are 10 Gbps capable, as well as integrated 1000BASE-T1 and 100BASE-T1 PHYs, providing greater flexibility and switching capacity needed to support automotive zonal electronic control unit (ECU) and central compute ECU architectures. Additionally, this switch is equipped with an advanced rule-based packet filter engine that can adapt to different vehicle operation modes to enhance driving safety.

In-vehicle networks continue to evolve with growing bandwidth demands and design complexity as the number of sensors, high-resolution cameras and displays increases. The zonal ECUs need to aggregate the data from these connected devices in real time and securely share them across central compute ECUs. The BCM8958X is optimized for use in both zonal ECUs and central compute ECUs that can switch and route large volumes of data for real time decision making. Together with the BroadR-Reach® PHYs (BCM8983X, BCM8988X, and BCM8989X) and sensor MCUs (BCM8910X), Broadcom provides the industry’s most comprehensive automotive Ethernet portfolio to enable an end-to-end network in the car.

SDV is emerging as the next wave of automotive network transformation, and its adoption is gaining strong traction. SDV eliminates the static nature of today’s in-vehicle networks and brings flexibility, programmability, and scalability to automotive networking to enable unprecedented real-time capabilities and cost efficiency across the automotive value chain. The BCM8958X provides the interface scalability, hardware virtualization, Layer 3 routing, MACsec and Layer 2 security needed to support new software applications and features for SDV.
