General Description

The 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 data operation

■Integrated 10/100M transceiver with 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/O
