BCM5325E
®
SIX-PORT MANAGED 10/100 ROBOswitch™
FEATURES
SUMMARY OF BENEFITS
• High level of integration:
• Five transceivers (802.3u compliant)
• Six Media Access Controllers (MACs) (802.3x compliant)
• 1-Mbit packet buffer and 512-Kbit control memory
• Non-blocking switching
• 802.1p QoS packet classification with four priority queues
• Port-based and 802.1Q-based VLAN with 16 entries
• 802.1d Spanning Tree
• Supports 802.1x EAPOL higher layer protocol
• Programmable storm control
• 1K MAC addresses with automatic learning and aging
• Programmable per port flow control and back-pressure
• MII or reversed MII
• MDC/MDIO and SPI interfaces
• WAN port and protected port support
• Port mirroring and IGMP layer 3 snooping
• Internal oscillator simplifies design and reduces cost
• 3.3V and 2.5V, power consumption is less than 1.0W
• BCM5325E/BCM5325U pin-to-pin compatible with
BCM5325M/BCM5325 respectively
• 128-pin MQFP package
• Enables a new generation of affordable five-port 10/100
switches with highest integration of enhanced L2+ features
• Utilizes field-proven industry-standard 10BASE-T/100BASE-
TX (100BASE-FX-compatible) Fast Ethernet transceivers—
lowering overall system interoperability and reliability risks
• 802.1Q based VLAN and flexible priority queues mapped to
selectable protocols such as 802.1p, DiffServ, and COS,
enables the switch to be designed into a wide variety of
applications for multimedia and data traffic
• Supports 802.1x for network security
• WAN port allows one of the ports to be specified for WAN
connectivity, in which case all traffic coming to the WAN port
is forwarded to the CPU
• Programmable per port storm provides better traffic
management
• MII port supports additional 100TX/FX
• Optional reversed MII port connects directly to an 802.3
compliant MAC
• Access to all internal registers through SPI or MDC/MDIO
interfaces
• Switch management features: Port statistic counters
