DM9000BIEP Datasheet PDF - Davicom Semiconductor

●General Description

●The DM9000BI is a fully integrated and cost-effective Industrial-grade 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 interface that support 3.3V with 5V IO tolerance.

●Features

●■ 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 IP/TCP/UDP checksum generation and checking

●■ Supports early Transmit

●■ 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.

●■ Supports Industrial-grade: -40 °C.~ +85°C

●■ 48-pin LQFP, 0.18 um process
