?25th

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

-

N on-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.

BCM5324M is designed based on the field-proven industry leader ROBOSwitch?. This device combines all the functions of a high-speed switch system including packet buffers, PHY transceivers, media access controllers, address management, and a non-blocking switch fabric into a single 0.13 μm CMOS device. It complies with IEEE 802.3specifications, including the MAC control PAUSE frame and auto-negotiation subsections, providing interoperability with all industry-standard Ethernet, Fast Ethernet and Gigabit Ethernet devices.BCM5324M is the industry first Ethernet to integrate twenty-four full-duplex 10BASE-T/100BASE-TX/FX Fast Ethernet transceivers. Each transceiver incorporates the Broadcom PHY Advance Cable Diagnostic technology, which can detect cable shorts as well as open and measure the cable length. BCM5324M also supports two GMII/RGMII/TBI interfaces, providing flexible 10/100/1000BASE-TX and fiber connectivity.

BCM5324M supports 8K MAC addresses, 4K VLAN addresses and CoS queues based on the Port ID, the MAC address, the 802.1p priority field in layer 2, the TOS field in IPv4 or the DiffServ field in IPv6headers. Together with other advanced features, such as 802.1x EAPOL protocol filtering, Port bandwidth/rate control, MAC address locking and IGMP snooping at Layer2 and Layer3 allow system vendors to build advanced L2+ switch systems for the multitenant/multidweller unit (MDU/MTU) markets.

The BCM5324M family of switches is optimized for Websmart and L2managed designs. The new level of integration brings L2 manageable to SMB switches at an affordable price. Single chip replaces the typical 3-or 4 chip solutions in the market today.

For Network Management, the BCM5324M includes 70+ on-chip MIB counters to collect receive and transmit statistics from each port for supporting the Etherlike MIB, Bridge MIB, MIB II (interfaces) and the RMON MIB (Groups 1, 2, 3, 9).Product ordering information:
