DM9000CEP-Ethernet Controller

The DM9000C 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.■ Supports automatically load vendor ID and product ID from EEPROM■ Optional EEPROM configuration■ Very low power consumption mode:– Power reduced mode (cable detection)– Power down mode– Selectable TX drivers for 1:1 or 1.25:1 transformers for additional power reduction.■ Compatible with 3.3V and 5.0V tolerant I/O■ DSP architecture PHY Transceiver.■ 48-pin LQFP, 0.18 um process■Supports processor interface: byte/word of I/O command to internal memory data operation■ Integrated 10/100M transceiver With HP Auto-MDIX■ Supports back pressure mode for half-duplex■ IEEE802.3x flow control for full-duplex mode■ Supports wakeup frame, link status change and magic packet events for remote wake up■ Support 100M Fiber interface.■ Integrated 16K Byte SRAM■ Build in 3.3V to 1.8V regulator■ Supports early Transmit■ Supports IP/TCP/UDP checksum generation andchecking
