DM9000AEP-Ethernet Controller

Ethernet Controller with General Processor InterfaceIntegrated 10/100M transceiverIntegrated 16K Byte SRAMBuild in 3.3V to 2.5V regulatorCompatible with 3.3V and 5.0V tolerant I/OThe DM9000A 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. Features:■48-pin LQFP■ Supports processor interface: byte/word of I/O command to internal memory dataoperation■ Integrated 10/100M transceiverwith HP Auto-MDIX■ Supports back pressure mode for half-duplex mode flow control■ 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 2.5V regulator■ Supports early Transmit■ Supports IP/TCP/UDP checksum generation and checking■ 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/OApplication VoIP CPE (ATA, IP Phone, Video Phone) IP STB, IPC, Internet Radio
