TECHNOLOGY

(Preliminary)

Integrated Fast Ethernet Controller

FEATURES

• Compliant to PCI bus interface v2.2.

• IEEE802.3 and 802.3u compliant.

• High performance with PCI bus master structure.

• Programmable PCI burst length for low CPU utili-

zation rate.

• Transmit packet queuing capability for higher per-

formance.

• Supports both full-duplex and half-duplex mode

operation.

• Supports both IEEE802.3x and XON/XOFF full

duplex flow control method.

• Contains separate transmit and receive FIFOs.

• Supports Magic packet and Microsoft wake-up

frame filtering.

• Supports ACPI and PCI power management.

• Supports CardBus STSCHG pin and status

changed registers. The CIS can be stored in the

EEPROM.

• Supports up to 128K bytes boot ROM or flash

memory without external latch.

• Autoload EEPROM contents after power-on.

• Programmable EEPROM interface.

• 128 pin PQFP package.

• Single 3.3V Power Supply.

GENERAL DESCRIPTION

MTD800 is a highly integrated fast ethernet

controller for PCI interface. The chip contains a PCI

interface block, two large FIFOs( each is 2KiloBytes )

for transmit and receive DMA, IEEE802.3 and 802.3u

compliant MAC interface for MII connection. Besides

that, the chip has the built-in Wake-Up controller to

perform ACPI function, and the capability of sensing

IEEE 802.3x frame to support XON/XOFF flow con-

trol protocol. The chip also has EEPROM and Boo-

tROM interface for no glue logic board

implementation. For CardBus application, MTD800

supports four status-changed registers, an interface

for accessing CIS which is stored in EEPROM and

STSCHG pin to reflect the general wake-up event.
