Broadcom BCM8950X 7-PORT INTEGRATED AUTOMOTIVE SWITCH

The BCM89500/BCM89501 devices are Broadcom's first fully integrated BroadR-Reach® multilayer switches to support 
automotive qualification (AECQ100) for in-car networking applications.

The BCM8950X family of products are the optimal solution for key automotive designs with high performance yet challenging low-power requirements.

Building upon 65 nm architecture, the BCM8950X family of products supports multiple intuitive low-power modes 
as well as an automotive cable diagnostics feature.

BCM89500 (*01)
176-pin 24 x 24 eLQFP package
4 (5) Integrated BroadR-Reach PHYs, 3 (2) uplink ports
