• Manufacturer Part Number: bcm53726
• Description: 16-port Gbe Highly Integrated Multilayer Switch Soc
• Manufacturer: Broadcom Corp.

The BCM53726 series is a complete L2 SoC solution for easy and rapid
development of Gigabit switching applications. The BCM53726
integrates 16 configurable 1-Gbps ports or 10-Mbps/100-Mbps Ethernet
ports.
The BCM53726 series is a highly integrated solution ideally suited for
stand-alone Gigabit Ethernet switches. It combines all the functions of a
high-speed switch system, including packet buffers, SerDes, media
access controllers, address management, a non-blocking switch fabric,
and integrated high-performance CPU into a single 65 nm CMOS
device. The BCM53726 series supports auto-DoS attack prevention and
SNMP, IEEE 802.1x, spanning tree, and rapid spanning tree protocols.
The BCM53726 switch:
• Integrates internal memory in the common buffer pool (CBP) for
• Provides 16-full-duplex GbE ports that interface to external physical
• Supports a Broadcom Serial Control (BSC) controller for
