Introduction
   The LAN9303M is a full featured, three-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 Ethernet switch system, including the Switch Fabric, packet buffers, Buffer Manger, 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 management protocol specifications, enabling compatibility with industry standard Ethernet and Fast Ethernet applications.
