DM9000 - ISA to Ethernet MAC Controller with Integrated 10/100 PHY - Davicom Datasheet

General Description
The DM9000 is a fully integrated and cost-effective single chip Fast Ethernet MAC 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 tolerance.

FEATUREs
■ Supports processor interface: byte/word/dword of I/O command to internal memory data operation
■ Integrated 10/100M transceiver
■  Supports MII and reverses MII interface
■  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
■ Integrated 4K dword SRAM
■  Supports automatically load vendor ID and product ID from EEPROM 
■Supports 4 GPIO pins
■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
■100-pin LQFP with CMOS process
