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.
