Features

•

Integrated Single-Chip 10/100/1000 Mbps

Ethernet Switch

16 10/100 Mbps Autosensing, Fast Ethernet

Ports with RMII or Serial Interface (7WS). Each

port can independently use one of the two

interfaces

2 Gigabit Ports with GMII, PCS and 10/100

interface options per port

Gigabit port supports hot swap in managed

configuration.

Supports 8/16-bit CPU interface in managed

mode

Serial interface in unmanaged mode

Supports two Frame Buffer Memory domains

with SRAM at 100 MHz

Supports memory size 2 MB, or 4 MB

Applies centralized shared memory architecture

Up to 64 K MAC addresses

Maximum throughput is 3.6 Gbps non-blocking

High performance packet forwarding (10.712 M

packets per second) at full wire speed

• Two SRAM domains (2 MB or 4 MB) are

required

•

Provides port based and ID tagged VLAN support

(IEEE 802.1Q), up to 255 VLANs

Supports IP Multicast with IGMP snooping

Supports spanning tree with CPU, on per port or

per VLAN basis

Packet Filtering and Port Security

Secure mode freezes MAC address learning.

Each port may independently use this mode.

Full Duplex Ethernet IEEE 802.3x Flow Control

Backpressure flow control for Half Duplex ports

Supports Ethernet multicasting and broadcasting

and flooding control

Supports per-system option to enable flow control

for best effort frames even on QoS-enabled ports

• Static address filtering for source and/or

• Static MAC address not subject to aging
