TC9204M is a fully integrated 4-Port 10/100/1000 smart Ethernet switch controller designed for low cost and high performance solutions. The chip embeds necessary SSRAM for packet buffering and MAC address table. TC9204M provides MII / GMII interface for all ports.
A store-and-forward switching method using anon-blocking architecture is implemented within TC9204M to improve the availability and bandwidth. The chip embeds SSRAM packet buffer, which it supports normal and priority queues for each transmission port. TC9204M provides evolved CoS with four levels of priority. The priority can be checked via layer 2 (802.1Q VLAN Tagging) and/or layer 3 (IP Header TOS bits) packets. Port based priority is also provided to ensure transmission with precedence for all packets incoming from selected port(s).
