Davicom DM9000CEP LQFP-48 Ethernet Controller IC

Description:

The DM9000C/CI is a industrial-temperature 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 interface that support 3.3V with 5V IO

tolerance.

The DM9000C/CI supports 8-bit and 16-bit data

interfaces to internal memory accesses for various

processors. The PHY of the DM9000C/CI can interface to

the UTP3, 4, 5 in 10Base-T and UTP5 in 100Base-TX with

HP Auto-MDIX. It is fully compliant with the IEEE 802.3u

Spec. Its auto-negotiation function will automatically

configure the DM9000C/CI to take the maximum advantage

of its abilities. The DM9000C/CI also supports IEEE 802.3x

full- duplex flow control.

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 early Transmit

■ Supports IP/TCP/UDP checksum generation and

checking

■ Supports industrial-temperature (-40℃ ~ +85℃)

(DM9000CIEP only)

■ 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.

■ 48-pin LQFP, 0.18 um process
