BCM5338M

NINE-PORT MANAGED 10/100 SWITCH WITH IEEE 802.1/P/X/Q VLAN

S U M M A R Y O F B E N E F I T S

F E A T U R E S

Sixth-generation L2+ Fast Ethernet switch on a chip

The BCM5338M integrates:

Enables a new generation of affordable 10/100 switches with

highest integration of enhanced L2+ features

•

Uses field-proven industry-standard 10BASE-T/100BASE-TX

(100BASE-FX compatible) Fast Ethernet transceivers—

lowering overall system interoperability and reliability risks

•

Eight transceivers (IEEE 802.3u compliant)

Nine medium access controllers (MACs) (IEEE 802.3x

compliant)

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

•

One port can be assigned as a WAN port

256-KB memory for packet buffer and control

Non-blocking switch fabric supports up to 24 ports

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

Cascades to 36 ports through a 3.2-Gbps expansion port

Stack to 48 ports with a 200-Mbps turbo MII port

•

IEEE 802.1p QoS packet classification with four priority

queues

Supports IEEE 802.1ad aggregation/port trunking

•

IEEE 802.1Q based VLAN with 512 entries

Supports IEEE 802.1x EAPOL higher layer protocol

MAC based trunking with automatic link failover

Programmable per port storm control and rate control

Port protection allows traffic aggregation to assigned port

4K MAC addresses with automatic learning and aging

Per port programmable MAC address locking

Programmable per port flow control and back pressure

Buffer repeater mode

•

Per port storm control of broadcast, multicast, and unlearned

unicast traffic

Flexible per port ingress/egress rate control with minimum

resolution of 48 Kbps for better traffic management

•

MAC address locking enhances security control

MII port supports additional 100TX/FX

•

Optional reversed MII port connects directly to an IEEE 802.3

compliant MAC

Access to all internal registers through SPI or MDC/MDIO

interfaces

•

Low-cost management using the on-chip MIB registers allows

the collection and transmission of basic management statistics

for each port

MII or reversed MII

MDC/MDIO and SPI interfaces

Switch management features:

•

Port mirroring and IGMP layer2/3 snooping

MIB Autocast^®function

•

Low-cost MIB Autocast function

Hardware support for Simple Network Management Protocol

(SNMP), remote network monitoring (RMON), IEEE 802.1d

spanning tree protocol, IEEE 802.1s multiple spanning tree (up

to 32), and IEEE 802.1w rapid spanning tree protocol

DTE (power over Ethernet)

Hardware support for SNMP, RMON, and STP

Internal oscillator simplifies design and reduces cost

JTAG

3.3V and 1.8V, and typical power consumption is less than 2W

BCM5328M pin-to-pin compatible 208-pin MQFP package
