GENERAL DESCRIPTION

The DM9010B is a fully integrated and cost-effective single chip Fast Ethernet MAC 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 tolerance.

FEATURES

■ 100-pin LQFP.

■ Supports processor interface: Byte/word/Dword of I/O command to internal memory data operation

■ Integrated 10/100M transceiver with HP Auto-MDIX

■ 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 16K Byte SRAM

■ Build in 3.3V to 1.8V regulator

■ Supports early Transmit

■ Supports IP/TCP/UDP checksum generation and checking

■ Supports automatically load vendor ID and product ID from EEPROM

■ Supports 7 or 23 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.

– 1: 1 transformers only when HP Auto-MDIX Enable.

■ Compatible with 3.3V and 5.0V tolerant I/O
