Microchip TechnologyLAN9646-I/MXXIC: Ethernet switch
The Microchip 6 port gigabit Ethernet switch with numerous advanced features with 4 of the 6 ports incorporate 10/100/1000 Mbps PHYs. The other two ports have interfaces that can be configured as SGMII, RGMII, MII or RMII. Either of these may connect directly to a host processor or to an external PHY. Full register access is available by SPI or I²C interfaces, and by optional in-band management via any of the data ports. PHY register access is provided by a MIIM interface. Full-chip software power-down Energy detect power-down Wake on LAN support Programmable rate limiting at ingress and egress ports Broadcast storm protection Self-address filtering for implementing ring topologies MAC filtering function to filter or forward unknown unicast, multicast and VLAN packets
