MTD502E

www.DataSheet4U.com MYSON TECHNOLOGY FEATURES 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 Independent Interface) ports. A flexible MII interface design can directly connect 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 forwarding 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). MTD502E 2 Port 10M/100M Switch With Build_in Memory GENERAL DESCRIPTION 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 forwarding, address filtering, learning, and aging function, and have an optional back_presure control implemented in half duplex mode. Th...
