SIX-PORT MANAGED 10/100 ROBOswitchâ¢
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 transceiversâ
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
