The BCM56580A0KFEBG is a high-performance Ethernet multilayer switch integrated circuit manufactured by Broadcom Limited. It features sixteen 2.5 Gigabit Ethernet ports and four 10 Gigabit Ethernet ports, designed for advanced switching applications. The component operates within a commercial temperature range and utilizes a specific surface-mount package configuration suitable for dense board layouts.
This component belongs to the Broadcom BCM565xx series of Ethernet switches. It serves as a specialized solution for environments requiring mixed speed port densities, bridging the gap between legacy Gigabit deployments and emerging 2.5G/10G standards without requiring multiple discrete controller chips.
Publicly confirmed substitute part numbers are not available in verified documentation. Engineering teams should consult official Broadcom lifecycle notices or authorized distributors for current obsolescence status and qualified alternative device recommendations.
