[MYSON TECHNOLOGY]

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.

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).
