BCM5338MKQM

The BCM5338MKQM is one member of the BCM5338 family which the following features:(1)Cascades to 36 ports through a 3.2-Gbps expansion port; (2)Stack to 48 ports with a 200-Mbps turbo MII port; (3)IEEE 802.1p QoS packet classification with four priority queues; (4)IEEE 802.1Q based VLAN with 512 entries; (5)Supports IEEE 802.1x EAPOL higher layer protocol; (6)MAC based trunking with automatic link failover; (7)Programmable per port storm control and rate control; (8)Port protection allows traffic aggregation to assigned port; (9)4K MAC addresses with automatic learning and aging; (10)Per port programmable MAC address locking; (11)Programmable per port flow control and back pressure; (12)Buffer repeater mode; (13)MII or reversed MII; (14)MDC/MDIO and SPI interfaces; (15)Port mirroring and IGMP layer2/3 snooping; (16)MIB Autocast function; (17)DTE (power over Ethernet); (18)Hardware support for SNMP, RMON, and STP; (19)Internal oscillator simplifies design and reduces cost; (20)JTAG; (21)3.3V and 1.8V, and typical power consumption is less than 2W; (22)BCM5328M pin-to-pin compatible 208-pin MQFP package.

And the benefits of the BCM5338MKQM can be summarized as:(1)Enables a new generation of affordable 10/100 switches with highest integration of enhanced L2+ features; (2)BCM5338MKQM uses field-proven industry-standard 10BASE-T/100BASE-TX; (3)(100BASE-FX compatible) Fast Ethernet transceivers lowering overall system interoperability and reliability risks; (4)IEEE 802.1Q based VLAN and flexible priority queues mapped to selectable protocols such as IEEE 802.1p, Diffserv, ToS, and CoS, enable the switch to be designed to a wide variety of applications for multimedia and data traffic; (5)Supports port based Extensible Authentication Protocol over LAN in four application modes; forwards only EAPOL frames to the CPU for authentication and allows secure mode traffic filtering; (6)BCM5338MKQM supports IEEE 802.1ad aggregation/port trunking; (7)Per port storm control of broadcast, multicast, and unlearned unicast traffic; (8)Flexible per port ingress/egress rate control with minimum resolution of 48 Kbps for better traffic management; (9)MAC address locking enhances security control; (10)MII port supports additional 100TX/FX; (11)Optional reversed MII port connects directly to an IEEE 802.3 compliant MAC; (12)Access to all internal registers through SPI or MDC/MDIO interfaces; (13)Low-cost management using the on-chip MIB registers allows the collection and transmission of basic management statistics for each port.
