BCM5325E ® SIX-PORT MANAGED 10/100 ROBOswitch™ SUMMARY OF BENEFITS FEATURES • High level of integration: • Enables a new generation of affordable five-port 10/100 • 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 switches with highest integration of enhanced L2+ features • Utilizes field-proven industry-standard 10BASE-T/100BASETX (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 • • • • • • • • • • • • 802.1d Spanning Tree Supports 802.1x EAPOL higher layer protocol Programmable storm control • WAN port allows one of the ports to be specified for WAN 1K MAC addresses with automatic learning and aging 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 Programmable per port flow control and back-pressure MII or reversed MII MDC/MDIO and SPI interfaces WAN port and protected port support • Optional reversed MII port connects directly to an 802.3 compliant MAC Port mirroring and IGMP layer 3 snooping • Access to all internal registers through SPI or MDC/MDIO Internal oscillator simplifies design and reduces cost interfaces 3.3V and 2.5V, power consumption is less than 1.0W • Switch management features: Port statistic counters BCM5325E/BCM5325U pin-to-pin compatible with BCM5325M/BCM5325 respectively • 128-pin MQFP package 5325E Block Diagram Auto MDI/MDIX 10/100 PHY MAC Auto MDI/MDIX 10/100 PHY MAC Auto MDI/MDIX 10/100 PHY MAC Auto MDI/MDIX 10/100 PHY MAC Auto MDI/MDIX 10/100 PHY MAC Port and 802.1Q based VLAN Port, 802.1p, MAC, IPv4/IPv6 DiffServ 4 CoS queues 802.1x & 802.1D MII / RvMII Interface CPU Interface MAC SPI / CPU Interface ARL Table Multicast Group IGMP Snooping OVERVIEW 5325F Block Diagram Auto MDI/MDIX 10/100 PHY MAC 0 Auto MDI/MDIX 10/100 PHY MAC 1 Auto MDI/MDIX 10/100 PHY MAC 2 Auto MDI/MDIX 10/100 PHY MAC 3 Port, 802.1p, MAC, IPv4/IPv6 DiffServ 4 CoS queues Auto MDI/MDIX 10/100 PHY MAC 4 802.1x & 802.1D MAC 5 ARL Table MII MII / RvMII Interface CPU Interface Voltage Regulator Port and 802.1Q based VLAN SPI / CPU Interface The BCM5325E is the feature-enhanced and pin-compatible six-port switch to the industry leader BCM5325M ROBOswitch™. This device combines all the functions of a high-speed switch system, including packet buffers, PHY transceivers, MACs, address management, and a non-blocking switch fabric, into a single 0.18-µm CMOS device. The BCM5325E complies with the IEEE 802.3, 802.3u, and 802.3x specifications, including the MAC control PAUSE frame and autonegotiation subsections, providing compatibility with all industrystandard Ethernet and Fast Ethernet devices. The BCM5325E contains five full-duplex 10BASE-T/100BASE-TX Fast Ethernet transceivers, each of which performs all of the physical layer interface functions for 10BASE-T Ethernet on Category 3, 4, or 5 Unshielded Twisted Pair (UTP) cable and 100BASE-TX Fast Ethernet on Category 5 UTP cable. Multicast Group IGMP Snooping pin-compatible to the industry five-port FE leader BCM5325M and BCM5325, respectively. The BCM5325F includes the PHY-MUX option where the fifth 10/100 PHY can be configured to connect to MAC 4, MAC 5 internally or external MAC via MII. This allows the flexible use of the fifth PHY for special application, or to be used with an external WAN MII interface, ideal for broadband and SOHO gateway/router applications. In addition to the robust 10/100 Ethernet DigiPHY, the five-port switch in the BCM5325E includes rich feature sets such as four priority queues supporting port, MAC, 802.1p, DiffServ-based Class of Service suitable for voice over IP, video, and data traffic for multimedia applications. In addition, BCM5325E supports other advance L2 managed features including port-based and 802.1Q VLAN, 802.1x EAPOL protocol filtering, IGMP snooping, and mirroring. The BCM5325E comes in the three options of BCM5325E, BCM5325F, and BCM5325U.
