It adopts the crossbar architecture to complete the function of packets switching between 4 MII ports. The mechanism of this switch is “learning & forwarding”, and the embedded MAC address table ensures the implementation of this function. It can attain wire speed when it's used as a fast Ethernet switch. 4-port Layer 2 Unmanaged Switched Ethernet Controller AT79C1010 Summary 3433AS–NETST–2/04 Note: This is a summary document. A complete document is available under NDA. For more information, please contact your local Atmel sales office. Figure 1.
