Bcm89885 ((better))
Broadcom does not release open-source drivers as aggressively as Linux-native vendors, but the BCM89885 is supported under:
, facilitating easy integration with automotive switches and SoCs. Automotive Qualification: AEC-Q100 qualified bcm89885
The BCM89885 uses "strapping pins" (pulled high or low via resistors during power-up) to determine its boot configuration (e.g., PHY address, interface mode, auto-negotiation). Ensure your schematic uses 10kΩ resistors for strapping; capacitive loading on these pins can cause misconfiguration during the POR (Power-On Reset) time. , meaning it is built to survive the
Traditionally, Gigabit Ethernet (1000BASE-T) required four pairs of wires, which is bulky, heavy, and expensive to route through a car. 1000BASE-T1, supported by the BCM89885, achieves the same 1 Gbps speed over a single pair. This reduction in cabling weight is critical for electric vehicles (EVs), where every gram saved contributes to increased driving range. which is bulky
, meaning it is built to survive the extreme temperatures and mechanical stresses of a vehicle environment. Core Features & Benefits Weight & Cost Reduction:
