We’re going to look back at 100BASE-T1 PHYs like the BCM89890 the same way we look at the CAN transceiver of the 1990s—as the unheralded hero that made the whole revolution possible. It’s not flashy, but without it, your car’s 17 cameras and 5 screens are just a pile of expensive glass and silicon.

Power consumption is a primary design constraint. The BCM89890 includes: We’re going to look back at 100BASE-T1 PHYs
Modern vehicles are moving from a domain-centric topology (e.g., one module for chassis, one for body) to a (e.g., left-front zone, right-front zone). In a zonal ECU, the BCM89890 serves as the edge PHY, aggregating sensor data from legacy CAN/I2C buses and converting it to Ethernet for backhaul to the central compute. Multiple BCM89890 devices often surround a Broadcom or Marvell switch chip. Design Advantages Power consumption is a primary design
