DM9000()EVB Datasheet PDF - Davicom Semiconductor

●The DM9000()EVB is an evaluation board for DM9000 Ethernet MAC controller. The DM9000 is a fully integrated and cost effective single chip fast Ethernet MAC controller with a general processor interface, a 10/100M PHY and 4K Dword SRAM. It is designed with low power and high performance process that support 3.3V with 5V tolerance. The DM9000 also provides a MII interface to connect HPNA device or other transceivers that support MII interface. It supports 8bit, 16bit and 32bit uP interfaces to internal memory accesses for different processors. The PHY of the DM9000 can interface to the UTP3, 4, 5 in 10Base-T and UTP5 in 100Base-TX. It is fully compliant with the IEEE 802.3u Spec. Its auto negotiation function will automatically configure the DM9000 to take the maximum advantage of its abilities. The DM9000 also supports IEEE 802.3x full duplex flow control. This programming of the DM9000 is very simple, so user can port the software drivers to any system easily.
