th
FE port via MII or Reversed MII mode for management

MDC/MDIO and SPI interfaces

Internal oscillator simplifies design and reduces cost

JTAG

Embedded 2.5V and 1.2V regulator, typical power
consumption: 3.5W

400-pin PBGA package

The BCM5324M includes:
- Twenty-four 10/100 transceivers for TX/FX
- Twenty-four media access controllers
- Two Gigabit media access controllers
- 3 Mb total of packet buffer and control memory
- Non-blocking switch fabric supports up to 24 FE+2 GE
ports

Advanced Cable Diagnostics minimize the need for expensive
cable troubleshooting equipment.

Enables a new generation of lower cost FE switches with the
highest integration of enhanced L2+ features and maximum
connectivity.

Optimized for WebSmart managed switch design.

802.1Q VLAN allows segmentation of network into smaller
broadcast domains to preserve bandwidth and increase
network security.

Four flexible Class of Service (CoS) queues per port assures
the lowest latency to high-priority traffic. This enables the
switch to support a wide variety of delay sensitive video and
audio multicast applications.

IEEE 802.3ad link aggregation increases effective bandwidth
and provides redundancy of a link.

IEEE 802.1X Extensive Authentication Protocol over LAN
(EAPOL) plus MAC address locking enhances network port
security.

Storm and Bandwidth/Rate Control provide better traffic
profile management.

Access to all internal registers through SPI or MDC/MDIO
interfaces.

Hardware support for implementing SNMP and RMON.

Low-power consumption and small package allow simple PCB
design.
