RTL8139CL

REALTEK 3.3V SINGLE CHIP FAST ETHERNET CONTROLLER WITH POWER MANAGEMENT

Realtek Semiconductor 

1. Features

128 pin QFP/LQFP

Integrated Fast Ethernet MAC, Physical chip and

transceiver in one chip

10 Mb/s and 100 Mb/s operation

Supports 10 Mb/s and 100 Mb/s N-way

Auto-negotiation operation

PCI local bus single-chip Fast Ethernet controller

Compliant to PCI Revision 2.2

Supports PCI clock 16.75MHz-40MHz

Supports PCI target fast back-to-back transaction

Provides PCI bus master data transfers and PCI memory

space or I/O space mapped data transfers of

RTL8139C(L)'s operational registers

Supports PCI VPD (Vital Product Data)

Supports ACPI, PCI power management

Supports CardBus. The CIS can be stored in 93C56 or

expansion ROM

Supports up to 128K bytes Boot ROM interface for both

EPROM and Flash memory

Supports 25MHz crystal or 25MHz OSC as the internal

clock source. The frequency deviation of either crystal or

OSC must be within 50 PPM.

Compliant to PC99 standard

Supports Wake-On-LAN function and remote wake-up

(Magic Packet*, LinkChg and Microsoft® wake-up

frame)

Supports 4 Wake-On-LAN (WOL) signals (active high,

active low, positive pulse, and negative pulse)

RTL8139C(L)

Supports auxiliary power-on internal reset, to be ready

for remote wake-up when main power still remains off

Supports auxiliary power auto-detect, and sets the

related capability of power management registers in PCI

configuration space.

Includes a programmable, PCI burst size and early

Tx/Rx threshold.

Supports a 32-bit general-purpose timer with the

external PCI clock as clock source, to generate

timer-interrupt

Contains two large (2Kbyte) independent receive and

transmit FIFO’s

Advanced power saving mode when LAN function or

wakeup function is not used

Uses 93C46 (64*16-bit EEPROM) or 93C56

(128*16-bit EEPROM) to store resource configuration,

ID parameter, and VPD data. The 93C56 can also be

used to store the CIS data structure for CardBus

application.

Supports LED pins for various network activity

indications

Supports digital and analog loopback capability on both

ports

Half/Full duplex capability

Supports Full Duplex Flow Control (IEEE 802.3x)

3.3V power supply with 5V tolerant I/Os.
