BL OCK DIAGRAM
The MTD502E is a highly integrated, 10M/
100M two port switch controller with build_in
embedded memory. It supports 2 MII/RMII ports
for 10M/100M operation, and both can operate
The MTD502E is an ideal solution for two
port bridge or dual speed hub application, and no
need any external memory buffers in application
design. The flexible MII interface design can
directly connect with pseudo MII interface
The MTD502E provides packet forwarding, address filtering, learning, and aging function, and have an optional back_presure control
address filtering database, which can recognize
up to 2048 MAC addresses. It also support an
automatical aging function for address table
