DAVICOM DM9000BEP 芯片, 以太网控制器, 10/100M PHY, 48LQFP
The is a fully integrated 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 interface that support 3.3V with 5V IO tolerance. The DM9000B supports 8-bit and 16-bit data interfaces to internal memory accesses for various processors. The PHY of the DM9000B 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 DM9000B to take the maximum advantage of its abilities. The DM9000B also supports IEEE 802.3x full-duplex flow control.
