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
• Two SRAM domains (2 MB or 4 MB) are
required
• 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

Ordering Information
ZL50418/GKC 553-pin HSBGA
-40°C to +85°C
• 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
• Static address filtering for source and/or
destination MAC
• Static MAC address not subject to aging
• 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
