    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


    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.


    ■ Supports processor interface: byte/word of I/O

    command to internal memory data operation

    ■ Integrated 10/100M transceiver With HP


    ■ 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

    (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
