www.DataSheet4U.com MYSON TECHNOLOGY FEATURES IEEE802.3 and IEEE802.3u compliant. Provide 16 RMII (Reduced Media Independent Interface) ports. Programmable 1K/8K MAC addresses filtering database. Store and forward switching function and bad packet filtering function. Optional back_pressure/802.3x flow control/ flooding control/broadcast control. Optional EEPROM Interface for advanced switch configurations. 4MB/2MB packet buffer with SGRAM/SDRAM flexible memory interface. Port VLAN/trunking. Link/Rx activity, packet buffer utilization LED display. 83MHz for non-blocking 16 port switch. Build in internal/external memory test function. 208 pin PQFP package, 3.3V operation voltage. MTD516 (Preliminary) GENERAL DESCRIPTION The MTD516 complies fully with the IEEE802.3, 802.3u and 802.3x specifications and is a non-blocking 16 port 10M/100M Ethernet switch device. Support 16 RMII ports for 10M/100M operation. 4MB memory interface provides maximum 2730 packet buffers for Ethernet packet buffering. Up to 8192 address entrys are provided by the MTD516, and the MTD516 use full Ethernet address compare algorithm to minimize hashing collision events. The MTD516 provides EEPROM interface to config port trunking, port VLAN, static entry, 802.3x flow control threshold, flooding port, broadcast control threshold. Each MTD516 ports support 10M/100M auto-negotiation by MII management interface. The MTD516 also provides 2 pins for Link/ RX activity, packet buffer utiliz...
