Bcm89890 [portable] Jun 2026

Before the BCM89890, automotive Ethernet was largely capped at 1 Gbps. By moving to 10 Gbps over a single pair of wires, Broadcom has allowed manufacturers to reduce cabling weight and complexity while significantly increasing the "IQ" of the vehicle. Its combination of high throughput, low latency, and hardware-based security makes it a foundational component for the next generation of intelligent transportation.

The Broadcom BCM89890 solves this paradigm by adapting enterprise-grade multigigabit Ethernet into a ruggedized, single-pair automotive framework. Technical Specifications and Core Capabilities

| Feature | Specification | | :--- | :--- | | | IEEE 802.3bp (1000BASE-T1) | | Data Rate | 1000 Mbps (Gigabit) | | Medium | Single Twisted Pair (UTP/STP) | | Interface | RGMII / SGMII | | Temperature Range | -40°C to +105°C (Automotive Grade) | | Package | VQFN (Very thin Quad Flat No-leads) | | Security | Hardware support for Secure Boot (optional variants) | bcm89890

The BCM89890 is small—a 6x6 mm QFN—but its impact on automotive networking is enormous.

The BCM89890 serves as the physical interface between the vehicle's network and high-speed processing units, featuring: Before the BCM89890, automotive Ethernet was largely capped

Optimized for time-critical automotive startups. ## Primary Applications

The BCM89890 has ultra-low-power sleep modes. When your car is “off,” this chip draws almost nothing. When you unlock the door, it wakes up in milliseconds. This is critical for EVs worried about 12V battery drain. The Broadcom BCM89890 solves this paradigm by adapting

To use the BCM89890 in a design, you'll need to consider the following:

The shift from domain-based architectures to zonal architectures requires a robust, high-speed backbone. The BCM89890 solves several critical problems for vehicle manufacturers: 1. Enabling Autonomous Driving (ADAS)

Fully compliant with IEEE 802.3ch 10G/5G/2.5GBASE-T1 standards.

Driving ultra-high-resolution 4K displays and complex rear-seat entertainment systems.
