Product Summary

The DM9000E 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. The DM9000E is designed with low power and high performance process that support 3.3V with 5V tolerance. The device also provides a MII interface to connect HPNA device or other transceivers that support MII interface. The DM9000E supports 8-bit, 16-bit and 32-bit uP interfaces to internal memory accesses for different processors.
