• Manufacturer Part Number: bcm53312s
• Description: 8-port Gbe 4-port Gbe Highly Integrated Multilayer Switch Soc
• Manufacturer: Broadcom Corp.

The BCM53312S is a complete L2 SoC solution for easy and rapid
development of gigabit switching applications. The BCM53312S
integrates 12 10/100/1000 wire speed switching processors. From a
GPHY interface perspective, it integrates eight GPHYs and four SGMII
SerDes cores. From a host interface perspective, it can use either
embedded MIPS processors or a PCI interface for external processor
connections.
The BCM53312S 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 an
integrated high-performance CPU into a single 65 nm CMOS device.
The BCM53312S supports auto DoS attack prevention and SNMP, IEEE
802.1x, Spanning Tree, and Rapid Spanning Tree protocols.
The BCM53312S switch:
• Integrates internal memory in the common buffer pool (CBP) for
• Integrates eight GPHYs to reduce PCB area.
• Embeds an autoVoIP engine to enhance user VoIP experience.
• Embeds an auto DoS prevention capability to enhance user security
