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 utilization LED display function. 16 Port 10M/100M Ethernet Switch BLOCK DIAGRAM SDRAM/ SGRAM Interface Memory Controller DMA0 MAC0 RMII0 DMA1 MAC1 RMII1 DMA2 Memory Arbiter MAC2 RMII2 DMA3 MAC3 RMII3 3~12 DMA4 MAC4 RMII12 DMA13 Port Switch Logic MAC13 RMII13 DMA14 MAC14 RMII14 DMA15 MAC15 RMII15 This datasheet contains new product information.
