PACKAGING 2 Data Sheet: ACD80800 The ACD80800 serves as an Address Resolution Logic for ACD’s switch controller chips (ACD82124, ACD82012 etc.) through a glueless ARL interface. It automatically builds up an address table and can map up to 8K MAC addresses into their associated ports. The ACD80800 can work without a CPU in a unmanaged switch system, or with a CPU and an ACD MIB (ACD80900 Management Information Base).
