Product Summary

The DM9000AEP is a fully integrated and cost-effective low pin count single chip Fast Ethernet 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 IO tolerance. The DM9000AEP supports 8-bit and 16-bit data interfaces to internal memory accesses for various processors. The DM9000AEP is fully compliant with the IEEE 802.3u Spec. Its auto-negotiation function will automatically configure the device to take the maximum advantage of its abilities. The device also supports IEEE 802.3x full-duplex flow control.
