SINGLE CHIP FAST ETHERNET CONTROLLER WITH POWER MANAGEMENT
General Description:
The Realtek RTL8139B(L) is a highly integrated and cost-effective single-chip Fast Ethernet
controller that provides 32-bit performance, PCI bus master capability, and full compliance with
IEEE 802.3u 100Base-T specifications and IEEE 802.3x Full Duplex Flow Control. It also
supports Advanced Configuration Power management Interface (ACPI), PCI power management
for modern operating systems that is capable of Operating System Directed Power Management
(OSPM) to achieve the most efficient power management. The RTL8139BL is suitable for the
applications of CardBus or mobile with built-in network controller. The CIS data can be stored in
either 93C56 EEPROM or expansion ROM. The RTL8139B is suitable for 5V signaling
environment only, such as modern Desktop environment.
Besides the ACPI feature, the RTL8139B(L) also supports remote wake-up (including Magic
Packet, LinkChg, and Microsoft wake-up frame) in both ACPI and APM environments. Especially,
the RTL8139B(L) is capable of performing internal reset whenever there is (auxiliary) power
applied to. Once the auxiliary power is on whereas the main power still remains off, the
RTL8139B(L) is ready and is waiting for the Magic packet or LinkChnage to wake the system up.
Also, the LWAKE pin provides 4 different output signals including active high, active low,
positive pulse, and negative pulse. The versatility of the RTL8139B(L) LWAKE pin satisfies all
kinds of motherboards with Wake-On-LAN (WOL) function. The RTL8139B(L) also supports
Analog Auto-Powerdown, that is, the analog part of the RTL8139B(L) can be shut down
temporarily according to the user's requirement or when the RTL8139B(L) is in power down
states with the wakeup function disabled. Besides, when the analog part is shut down and the
IsolateB pin is low (i.e. the main power is off), then both the analog and digital parts stop
functioning and the RTL8139B(L) will achieve the most power saving and consume extremely
minor power.
The PCI Vital Product Data (VPD) is also supported to provide the information that uniquely
identifies hardware (i.e., the RTL8139B(L) net card). The information may consist of part number,
serial number, and other detailed information, and so on.
For sake of cost-down, the RTL8139B(L) is capable of applying 20MHz crystal as its internal
clock source. The 50MHz OSC is still supported, too.
The RTL8139B(L) keeps network maintenance cost low and eliminates usage barriers. It is the
easiest way to upgrade a network from 10 to 100Mbps. It also supports full-duplex operation,
making possible 200Mbps of bandwidth at no additional cost. The RTL8139B(L) is highly
integrated and requires no "glue" logic or external memory. It includes an interface for a boot
ROM and can be used in diskless workstations, providing maximum network security and ease
of management.
Features of 8139B(L):
¡@
128 pins 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
RTL8139B(L)'s operational registers
Supports PCI VPD (Vital Product Data)
Supports ACPI, PCI power
management
The RTL8139BL works in 3.3V
signaling environment mainly, and the
RTL8139B is used in 5V signaling
environment only. Both need 5-volt
working voltage inside.
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 50MHz OSC
as the internal clock source. The
frequency deviation of either crystal or
OSC must be within 50 PPM.
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)
Supports auxiliary power-on internal reset,
to be ready for remote wake-up when main
power still remains off
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)

Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
