LAN9303M-AKZE

The LAN9303M is a full featured, 3 port 10/100 managed Ethernet switch designed for embedded applications where performance, flexibility, ease of integration and system cost control are required. The LAN9303M combines all the functions of a 10/100 switch system, including the Switch Fabric, packet buffers, Buffer Manager, Media Access Controllers (MACs), PHY transceivers, and serial management. The LAN9303M complies with the IEEE 802.3 (full/half-duplex 10BASE-T and 100BASE-TX) Ethernet protocol specification and 802.1D/802.1Q network management protocol specifications, enabling compatibility with industry standard Ethernet and Fast Ethernet applications.

• Ethernet Switch Fabric
  • 32K buffer RAM
  • 512 entry forwarding table
  • Port based IEEE 802.1Q VLAN support (16 groups) – Programmable IEEE 802.1Q tag insertion/removal
  • IEEE 802.1D spanning tree protocol support
  • 4 separate transmit queues available per port
  • Fixed or weighted egress priority servicing
  • QoS/CoS Packet prioritization – Input priority determined by VLAN tag, DA lookup,
• TOS, DIFFSERV or port default value – Programmable Traffic Class map based on input priority on per port basis – Remapping of 802.1Q priority field on per port basis – Programmable rate limiting at the ingress with coloring and random early discard, per port / priority – Programmable rate limiting at the egress with leaky bucket algorithm, per port / priority
  • IGMP v1/v2/v3 monitoring for Multicast packet filtering
  • Programmable broadcast storm protection with global % control and enable per port
