标题：Eric_chu:向大家推荐一款嵌入式的高速以太网芯片
摘要：No.87081向大家推荐一款嵌入式的高速以太网芯片 高速乙太網路晶片 > DM9000A
The DM9000A is a fully integrated and cost-effective low pin count single chip Fast controller with a general processor interface,a 10/100M PHY and 16K Byte SRAM. It is designed with low power and high performance process that support 3.3V with 5V IO tolerance.
The DM9000A supports 8-bit and 16-bit data interfaces to internal memory accesses for various processors. The PHY of the DM9000A can interface to the UTP3, 4, 5 in 10Base-T and UTP5 in 100Base-TX with AUTO-MDIX. It is fully compliant with the IEEE 802.3u Spec. Its auto-negotiation function will automatically configure the DM9000A to take the maximum advantage of its abilities. The DM9000A also supports IEEE 802.3x full- duplex flow control.
Features
■ 48-pin LQFP
■ Supports processor interface: byte/word of I/O command to internal memory data operation
■ Integrate ......
