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. It supports 8-bit and 16-bit data interfaces to internal memory accesses for various processors. The applications of the The DM9000AEP inlucde VoIP CPE (ATA, IP Phone, Video Phone) and IP STB, IPC, Internet Radio. The PHY of the DM9000AEP can interface to the UTP3, 4, 5 in 10Base-T and UTP5 in 100Base-TX with HP Auto-MDIX. It is fully compliant with the IEEE 802.3u Spec. Its auto-negotiation function will automatically configure the DM9000AEP to take the maximum advantage of its abilities. It also supports IEEE 802.3x full- duplex flow control.
