: Features built-in 802.1AE MACsec with 128/256-bit AES encryption, providing hardware-level security to protect in-vehicle data from cyberattacks and breaches.
Features multiple low-power modes to reduce energy consumption.
Connecting high-resolution 4K cameras, Lidar, and 4D radar sensors. Infotainment: bcm89890
In a zonal architecture, the vehicle is divided into physical zones, each managed by a gateway controller. These gateways aggregate data from local sensors and actuators and require a high-speed uplink to a central compute unit. The BCM89890 is ideal for such ECU-to-ECU backbone communications.

To use the BCM89890 in a design, you'll need to consider the following:
To appreciate the significance of the BCM89890, one must first understand the context of the Single Pair Ethernet (SPE) technology it champions. Invented by Broadcom over a decade ago under the brand BroadR-Reach®, SPE technology was a transformative departure from traditional in-vehicle cabling. It enabled high-speed data transmission over a single, lightweight, unshielded twisted-pair cable, replacing heavier, more expensive solutions like LVDS (Low-Voltage Differential Signaling). This innovation brought substantial cost and weight savings, a critical factor for enhancing electric vehicle (EV) range and efficiency. Infotainment: In a zonal architecture, the vehicle is

is designed for the most bandwidth-intensive applications in modern vehicle architecture:
Broadcom has integrated hardware security features (MACsec support) into this line, which is becoming increasingly important as cars become connected devices vulnerable to hacking. From a design perspective, it integrates the termination resistors, reducing the Bill of Materials (BOM) count for engineers designing the PCBs.
