MTD502E
TECHNOLOGY
2 Port 10M/100M Switch With Build_in Memory
FEATURES
GENERAL DESCRIPTION
• IEEE802.3 and IEEE802.3u compliant.
• Single chip, low cost, two port switch controller.
• Build_in embedded memory on chip for packet
buffering.
• Provide 2 MII/RMII (Reduced Media Indepen-
dent Interface) ports.
• A flexible MII interface design can directly con-
nect with standard MII or pseudo MII.
• Support half/full duplex operation per port.
• Optional back_pressure control for half_duplex
mode.
• Provide “store and forward” switching, and for-
warding rate at full_wire speed.
• Support up to 2048 MAC addresses filtering
database, and automatical address aging_out
function (300 secs).
• Low power CMOS design, with single 3.3V
supply voltage, 50 MHZ operation.
• Provide 128 pin PQFP package (MTD502EF),
and 80 pin LQFP package (MTD502EG).
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
under half or full duplex mode.
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
(Am79c901, HomePNA PHY).
The MTD502E provides packet forward-
ing, address filtering, learning, and aging func-
tion, and have an optional back_presure control
implemented in half duplex mode.
The MTD502E supports an effective
address filtering database, which can recognize
up to 2048 MAC addresses. It also support an
automatical aging function for address table
updating (aging time is 300 secs default).
