a built-in 2K entries of address table and supports a 4Mb external SSRAM. T71L6816A is
also a high performance Fast-Ethernet switch with fully compliance with the IEEE802.3,
802.3u and 802.3x specifications. The T71L6816A can be implemented with external PHY chips
and 4Mb pipe-line SSRAM. By default, it is targeted for applications to the stand-alone
switch for low-cost SOHO and small enterprise market.
