RTL8139DL
Datasheet
1. General Description
The Realtek RTL8139D(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 are capable of Operating System Directed Power Management (OSPM) to achieve the most
efficient power management possible. The RTL8139D(L) also supports shared Boot ROM pins & clock run
pin.
In addition to the ACPI feature, the RTL8139D(L) also supports remote wake-up (including AMD Magic
Packet, LinkChg, and Microsoft® wake-up frame) in both ACPI and APM environments. The
RTL8139D(L) is capable of performing an internal reset through the application of auxiliary power. When
auxiliary power is applied and the main power remains off, the RTL8139D(L) is ready and is waiting for
the Magic Packet or Link Change 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
RTL8139D(L) LWAKE pin provides motherboards with Wake-On-LAN (WOL) functionality.
The RTL8139D(L) also supports Analog Auto-Power-down, that is, the analog part of the RTL8139D(L)
can be shut down temporarily according to user requirement or when the RTL8139D(L) is in a power down
state with the wakeup function disabled. In addition, 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 power
consumption of the RTL8139D(L) will be negligible. The RTL8139D(L) also supports an auxiliary power
auto-detect function, and will auto-configure related bits of their own PCI power management registers in
PCI configuration space.
PCI Vital Product Data (VPD) is also supported to provide the information that uniquely identifies
hardware (Ex., the OEM brand name of RTL8139D(L) LAN card). The information may consist of part
number, serial number, and other detailed information.
To provide cost down support, the RTL8139D(L) is capable of using a 25MHz crystal or OSC as its internal
clock source.
The RTL8139D(L) keeps network maintenance costs 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 200Mbps
bandwidth possible at no additional cost. To improve compatibility with other brands’ products, the
RTL8139D(L) is also capable of receiving packets with InterFrameGap no less than 40 Bit-Time. The
RTL8139D(L) is highly integrated and requires no “glue” logic or external memory.
The RTL8139D(L) provides a flexible multi-function mode (Realtek patent pending) to incorporate other
PCI master devices, like a hardware modem. When in multi-function mode, the RTL8139D(L) acts as an
arbiter to distinguish LAN signals from those of other devices. The second device recognizes no difference
between being connected to the RTL8139D or a regular PCI bus.
The RTL8139D(L) includes a PCI and Expansion Memory Share Interface (Realtek’s patent pending) for a
boot ROM and can be used in diskless workstations, providing maximum network security and ease of
management.

4. Pin Descriptions
Note that some pins have multiple functions. Refer to the Pin Assignment diagrams for a graphical
representation.
4.1. Power Management/Isolation Interface
Symbol Type Pin No Description
PMEB O/D 57 Power Management Event: Open drain, active low. Used by the
(PME#)
RTL8139D(L) to request a change in its current power management
state and/or to indicate that a power management event has occurred.
ISOLATEB I 74 Isolate pin: Active low. Used to isolate the RTL8139D(L) from the PCI
(ISOLATE#)
bus. The RTL8139D(L) does not drive its PCI outputs (excluding
PME#) and does not sample its PCI input (including RST# and
PCICLK) as long as the Isolate pin is asserted.
LWAKE O 64 LAN WAKE-UP signal: This signal is used to inform the motherboard
to execute the wake-up process. The motherboard must support
Wake-On-LAN (WOL). There are 4 choices of output, including active
high, active low, positive pulse, and negative pulse, that may be asserted
from the LWAKE pin. Please refer to the LWACT bit in the CONFIG1
register and the LWPTN bit in the CONFIG4 register for the setting of
this output signal. The default output is an active high signal.
Once a PME event is received, the LWAKE and PMEB assert at the
same time when the LWPME (bit4, CONFIG4) is set to 0. If the
LWPME is set to 1, the LWAKE asserts only when the PMEB asserts
and the ISOLATEB is low.
This pin is a 3.3V signaling output pin.
4.2. PCI Interface
Symbol Type Pin No Description
AD31-0 T/S 86,87,89,91-95,100, PCI address and data multiplexed pins.
1,3-5,8-10,23-30,33, Pins AD31-24 are shared with BootROM data pins, while AD16-0 are
36-38,41,42,44,45 shared with BootROM address pins.
C/BE3-0 T/S 98,11,21,32 PCI bus command and byte enables multiplexed pins.
CLK I 83 Clock: This PCI Bus clock provides timing for all transactions and bus
phases, and is input to PCI devices. The rising edge defines the start of
each phase. The clock frequency ranges from 0 to 33MHz.
DEVSELB S/T/S 15 Device Select: As a bus master, the RTL8139D(L) samples this signal
to insure that a PCI target recognizes the destination address for the data
transfer. As a target, the RTL8139D(L) asserts this signal low when it
recognizes its target address after FRAMEB is asserted.
FRAMEB S/T/S 12
Cycle Frame: As a bus master, this pin indicates the beginning and
duration of an access. FRAMEB is asserted low to indicate the start of a
bus transaction. While FRAMEB is asserted, data transfer continues.
When FRAMEB is deasserted, the transaction is in the final data phase.
As a target, the device monitors this signal before decoding the address
to check if the current transaction is addressed to it.

RTL8139DL
Datasheet
Symbol Type Pin No Description
GNTB I 84 Grant: This signal is asserted low to indicate to the RTL8139D(L) that
the central arbiter has granted ownership of the bus to the
RTL8139D(L). This input is used when the RTL8139D(L) is acting as a
bus master.
REQB T/S 85 Request: The RTL8139D(L) will assert this signal low to request the
ownership of the bus from the central arbiter.
IDSEL I 99 Initialization Device Select: This pin allows the RTL8139D(L) to
identify when configuration read/write transactions are intended for it.
INTAB O/D 81 INTAB: Used to request an interrupt. It is asserted low when an
interrupt condition occurs, as defined by the Interrupt Status, Interrupt
Mask and Interrupt Enable registers.
IRDYB S/T/S 13 Initiator Ready: This indicates the initiating agent’s ability to complete
the current data phase of the transaction.
As a bus master, this signal will be asserted low when the RTL8139D(L)
is ready to complete the current data phase transaction. This signal is used
in conjunction with the TRDYB signal. Data transaction takes place at the
rising edge of CLK when both IRDYB and TRDYB are asserted low. As
a target, this signal indicates that the master has put data on the bus.
TRDYB S/T/S 14
Target Ready: This indicates the target agent’s ability to complete the
current phase of the transaction.
As a bus master, this signal indicates that the target is ready for the data
during write operations and with the data during read operations. As a
target, this signal will be asserted low when the (slave) device is ready
to complete the current data phase transaction. This signal is used in
conjunction with the IRDYB signal. Data transaction takes place at the
rising edge of CLK when both IRDYB and TRDYB are asserted low.
PAR T/S 20 Parity: This signal indicates even parity across AD31-0 and C/BE3-0
including the PAR pin. As a master, PAR is asserted during address and
write data phases. As a target, PAR is asserted during read data phases.
PERRB S/T/S 18 Parity Error: When the RTL8139D(L) is the bus master and a parity
error is detected, the RTL8139D(L) asserts both SERR bit in ISR and
Configuration Space command bit 8 (SERRB enable). Next, it
completes the current data burst transaction, then stops operation and
resets itself. After the host clears the system error, the RTL8139D(L)
continues its operation.
When the RTL8139D(L) is the bus target and a parity error is detected,
the RTL8139D(L) asserts this PERRB pin low.
SERRB O/D 19 System Error: If an address parity error is detected and Configuration
Space Status register bit 15 (detected parity error) is enabled,
RTL8139D(L) asserts both SERRB pin low and bit 14 of Status register
in Configuration Space.
STOPB S/T/S 17 Stop: Indicates the current target is requesting the master to stop the
current transaction.
RSTB I 82
Reset: When RSTB is asserted low, the RTL8139D(L) performs
internal system hardware reset. RSTB must be held for a minimum of
120 ns.

4.3. EEPROM Interface
Symbol Type Pin No Description
AUX I 50 Aux. Power Detect: This pin is used to notify the RTL8139D(L) of the
existence of Aux. power during initial power-on or a PCI reset.
This pin should be pulled high to the Aux. power via a resistor to detect
the Aux. power. Doing so, will enable wakeup support from ACPI D3
cold or APM power-down. If this pin is not pulled high, the
RTL8139D(L) assumes that no Aux. power exists.

5.2. Transmit Status Register
(TSD0-3)(Offset 0010h-001Fh, R/W)
The read-only bits (CRS, TABT, OWC, CDH, NCC3-0, TOK, TUN) will be cleared by the RTL8139D(L)
when the Transmit Byte Count (bits 12-0) in the corresponding Tx descriptor is written. It is not affected
when software writes to these bits. These registers are only permitted to write by double-word access. After
software reset, all bits except OWN bit are reset to “0”.
Bit R/W Symbol Description
31 R CRS
Carrier Sense Lost: This bit is set to 1 when the carrier is lost during
transmission of a packet.
30 R TABT Transmit Abort: This bit is set to 1 if the transmission of a packet was
aborted. This bit is read only, writing to this bit is not affected.
29 R OWC Out of Window Collision: This bit is set to 1 if the RTL8139D(L)
encountered an "out of window" collision during the transmission of a
packet.
28 R CDH
CD Heart Beat: The NIC watches for a collision signal (ie, CD
Heartbeat signal) during the first 6.4us of the interframe gap following a
transmission. This bit is set if the transceiver fails to send this signal.
This bit is cleared in the 100 Mbps mode.
27-24 R NCC3-0 Number of Collision Count: Indicates the number of collisions
encountered during the transmission of a packet.
23-22 - - Reserved
21-16 R/W ERTXTH5-0 Early Tx Threshold: Specifies the threshold level in the Tx FIFO to
begin the transmission. When the byte count of the data in the Tx FIFO
reaches this level, (or the FIFO contains at least one complete packet)
the RTL8139D(L) will transmit this packet.
000000 = 8 bytes
These fields count from 000001 to 111111 in unit of 32 bytes.
This threshold must avoid exceeding 2K bytes.
15 R TOK Transmit OK: Set to 1 indicates that the transmission of a packet was
completed successfully and no transmit underrun has occurred.
14 R TUN Transmit FIFO Underrun: Set to 1 if the Tx FIFO was exhausted
during the transmission of a packet. The RTL8139D(L) can re-transfer
data if the Tx FIFO underruns and can also transmit the packet to the
wire successfully even though the Tx FIFO underruns. That is, when
TSD=1, TSD=0 and ISR=1 (or ISR=1).
13 R/W OWN OWN: The RTL8139D(L) sets this bit to 1 when the Tx DMA
operation of this descriptor was completed. The driver must set this bit
to 0 when the Transmit Byte Count (bits 0-12) is written. The default
value is 1.
12-0 R/W SIZE Descriptor Size: The total size in bytes of the data in this descriptor. If
the packet length is more than 1792 byte (0700h), the Tx queue will be
invalid, i.e. the next descriptor will be written only after the OWN bit of
that long packet's descriptor has been set.

Bit R/W Symbol Description
7-4 - -
Reserved
3 R ERGood Early Rx Good packet: This bit is set whenever a packet is completely
received and the packet is good. Writing a 1 to this bit will clear it.
2 R ERBad
Early Rx Bad packet: This bit is set whenever a packet is completely
received and the packet is bad. Writing a 1 to this bit will clear it.
1 R EROVW Early Rx OverWrite: This bit is set when the RTL8139D(L)'s local
address pointer is equal to CAPR. In the early mode, this is different
from buffer overflow. It happens that the RTL8139D(L) detected an Rx
error and wanted to fill another packet data from the beginning address
of that error packet. Writing a 1 to this bit will clear it.
0 R EROK
Early Rx OK: The power-on value is 0. It is set when the Rx byte count
of the arriving packet exceeds the Rx threshold. After the whole packet
is received, the RTL8139D(L) will set ROK or RER in ISR and clear
this bit simultaneously. Setting this bit will invoke a ROK interrupt.
5.4. Command Register
(Offset 0037h, R/W)
This register is used for issuing commands to the RTL8139D(L). These commands are issued by setting the
corresponding bits for the function. A global software reset along with individual reset and enable/disable
for transmitter and receiver are provided here.
Bit R/W Symbol Description
7-5 - - Reserved
4 R/W RST Reset: Setting to 1 forces the RTL8139D(L) to a software reset state
which disables the transmitter and receiver, reinitializes the FIFOs,
resets the system buffer pointer to the initial value (Tx buffer is at
TSAD0, Rx buffer is empty). The values of IDR0-5 and MAR0-7 and
PCI configuration space will have no changes. This bit is 1 during the
reset operation, and is cleared to 0 by the RTL8139D(L) when the reset
operation is complete.
3 R/W RE
Receiver Enable: When set to 1, and the receive state machine is idle,
the receive machine becomes active. This bit will read back as a 1
whenever the receive state machine is active. After initial power-up,
software must insure that the receiver has completely reset before
setting this bit.
2 R/W TE Transmitter Enable: When set to 1, and the transmit state machine is
idle, then the transmit state machine becomes active. This bit will read
back as a 1 whenever the transmit state machine is active. After initial
power-up, software must insure that the transmitter has completely reset
before setting this bit.

5.5. Interrupt Mask Register
(Offset 003Ch-003Dh, R/W)
This register masks the interrupts that can be generated from the Interrupt Status Register. A hardware reset
will clear all mask bits. Setting a mask bit allows the corresponding bit in the Interrupt Status Register to
cause an interrupt. The Interrupt Status Register bits are always set to 1 if the condition is present,
regardless of the state of the corresponding mask bit.

5.6. Interrupt Status Register
(Offset 003Eh-003Fh, R/W)
This register indicates the source of an interrupt when the INTA pin goes active. Enabling the
corresponding bits in the Interrupt Mask Register (IMR) allows bits in this register to produce an interrupt.
When an interrupt is active, one of more bits in this register are set to a “1”. The interrupt Status Register
reflects all current pending interrupts, regardless of the state of the corresponding mask bit in the IMR.
Reading the ISR clears all interrupts. Writing to the ISR has no effect.

5 R/W Magic Magic Packet: This bit is valid when the PWEn bit of the CONFIG1
register is set. The RTL8139D(L) will assert the PMEB signal to wakeup the
operating system when the Magic Packet is received.
Once the RTL8139D(L) has been enabled for Magic Packet wakeup and
has been put into adequate state, it scans all incoming packets addressed to
the node for a specific data sequence, which indicates to the controller that
this is a Magic Packet frame. A Magic Packet frame must also meet the basic
requirements of:
Destination address + Source address + data + CRC
The destination address may be the node ID of the receiving station or a
multicast address, which includes the broadcast address.
The specific sequence consists of 16 duplications of 6 byte ID registers,
with no breaks or interrupts. This sequence can be located anywhere within
the packet, but must be preceded by a synchronization stream, 6 bytes of
FFh. The device will also accept a multicast address, as long as the 16
duplications of the IEEE address match the address of the ID registers.
If the Node ID is 11h 22h 33h 44h 55h 66h, then the magic frame’s format
is similar to the following:
Destination address + source address + MISC + FF FF FF FF FF FF +
MISC + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22

6. EEPROM (93C46) Contents
The 93C46 is a 1K-bit EEPROM. Although it is addressed by words, we list its contents by bytes below for
convenience.
The 93C46 is a 1K-bit EEPROM. Although it is actually addressed by words, its contents are listed below
by bytes for convenience. After the valid duration of the RSTB pin or auto-load command in the 9346CR,
the RTL8139D(L) performs a series of EEPROM read operations from the 93C46 addresses 00H to 31H.
It is suggested to obtain Realtek approval before changing the default settings of the EEPROM.
Bytes Contents Description
00h 29h These 2 bytes contain the ID code word for the RTL8139D(L). The RTL8139D(L) will

right, otherwise, the RTL8139D(L) will not proceed with the EEPROM autoload
process.

12, 8 of the Basic Mode Control register (BMCR); Bits 3-2 are reserved. If the network
speed is set to Auto-Detect mode (i.e. Nway mode), then Bit 1=0 means the local
RTL8139D(L) supports flow control (IEEE 802.3x). In this case, Bit 10=1 in the
Auto-negotiation Advertisement Register (offset 66h-67h), and Bit 1=1 means the local
RTL8139D(L) does not support flow control. In this case, Bit 10=0 in Auto-negotiation
Advertisement. This is because there are Nway switch hubs which keep sending flow
control pause packets for no reason, if the link partner supports Nway flow control.

7.2. PCI Configuration Space Functions
The PCI configuration space is intended for configuration, initialization, and catastrophic error handling
functions. The functions of the RTL8139D(L)'s configuration space are described below.
VID: Vendor ID. This field will default to a value of 10ECh which is Realtek Semiconductor's PCI Vendor
ID.
DID: Device ID. This field will default to a value of 8139h.
Command: The command register is a 16-bit register used to provide coarse control over a device's ability
to generate and respond to PCI cycles.
Bit Symbol Description
15-10 - Reserved
9 FBTBEN Fast Back-To-Back Enable: Config3=0:Read as 0. Write operation has no effect. The
RTL8139D(L) will not generate Fast Back-to-back cycles. When Config3=1, This
read/write bit controls whether or not a master can do fast back-to-back transactions to different
devices. Initialization software will set the bit if all targets are fast back-to-back capable. A value of 1
means the master is allowed to generate fast back-to-back transaction to different agents. A value of 0
means fast back-to-back transactions are only allowed to the same agent. This bit’s state after RST# is
0.
8 SERREN System Error Enable: When set to 1, the RTL8139D(L) asserts the SERRB pin when it detects a
parity error on the address phase (AD<31:0> and CBEB<3:0> ).
7 ADSTEP Address/Data Stepping: Read as 0, write operation has no effect. The RTL8139D(L) never make
address/data stepping.
6 PERRSP Parity Error Response: When set to 1, the RTL8139D(L) will assert the PERRB pin on the detection
of a data parity error when acting as the target, and will sample the PERRB pin as the master. When set
to 0, any detected parity error is ignored and the RTL8139D(L) continues normal operation.
Parity checking is disabled after hardware reset (RSTB).
5 VGASNOO
VGA palette SNOOP: Read as 0, write operation has no effect.
P
4 MWIEN Memory Write and Invalidate cycle Enable: Read as 0, write operation has no effect.
3 SCYCEN Special Cycle Enable: Read as 0, write operation has no effect. The RTL8139D(L) ignores all special
cycle operation.
2 BMEN Bus Master Enable: When set to 1, the RTL8139D(L) is capable of acting as a bus master. When set
to 0, it is prohibited from acting as a PCI bus master.
For the normal operation, this bit must be set by the system BIOS.
1 MEMEN Memory Space Access: When set to 1, the RTL8139D(L) responds to memory space accesses. When
set to 0, the RTL8139D(L) ignores memory space accesses.
0 IOEN I/O Space Access: When set to 1, the RTL8139D(L) responds to IO space access. When set to 0, the
RTL8139D(L) ignores I/O space accesses.

Status: The status register is a 16-bit register used to record status information for PCI bus related events.
Reads to this register behave normally. Writes are slightly different in that bits can be reset, but not set.
Bit Symbol Description
15 DPERR Detected Parity Error: When set indicates that the RTL8139D(L) detected a parity error, even if parity
error handling is disabled in command register PERRSP bit.
14 SSERR Signaled System Error: When set indicates that the RTL8139D(L) asserted the system error pin,
SERRB. Writing a 1 clears this bit to 0.
13 RMABT Received Master Abort: When set indicates that the RTL8139D(L) terminated a master transaction
with master abort. Writing a 1 clears this bit to 0.
12 RTABT Received Target Abort: When set indicates that the RTL8139D(L) master transaction was terminated
due to a target abort. Writing a 1 clears this bit to 0.
11 STABT Signaled Target Abort: Set to 1 whenever the RTL8139D(L) terminates a transaction with target abort.
Writing a 1 clears this bit to 0.
10-9 DST1-0 Device Select Timing: These bits encode the timing of DEVSELB. They are set to 01b (medium),
indicating the RTL8139D(L) will assert DEVSELB two clocks after FRAMEB is asserted.
8 DPD
Data Parity error Detected:
This bit sets when the following conditions are met:
► The RTL8139D(L) asserts parity error(PERRB pin) or it senses the assertion of PERRB pin by another device.
► The RTL8139D(L) operates as a bus master for the operation that caused the error.
► The Command register PERRSP bit is set.
Writing a 1 clears this bit to 0.
7 FBBC
Fast Back-To-Back Capable: Config3=0, Read as 0, write operation has no effect.
Config3=1, Read as 1.
6 UDF User Definable Features Supported: Read as 0, write operation has no effect. The RTL8139D(L) does
not support UDF.
5 66MHz 66 MHz Capable: Read as 0, write operation has no effect. The RTL8139D(L) has no 66MHz
capability.

RID: Revision ID Register
The Revision ID register is an 8-bit register that specifies the RTL8139D(L) controller revision number.
PIFR: Programming Interface Register
The programming interface register is an 8-bit register that identifies the programming interface of the RTL8139D(L)
controller. Because the PCI version 2.1 specification does not define any specific value for network devices, PIFR = 00h.
SCR: Sub-Class Register
The Sub-class register is an 8-bit register that identifies the function of the RTL8139D(L). SCR = 00h indicates that the
RTL8139D(L) is an Ethernet controller.
BCR: Base-Class Register
The Base-class register is an 8-bit register that broadly classifies the function of the RTL8139D(L). BCR = 02h indicates
that the RTL8139D(L) is a network controller.
CLS: Cache Line Size
Reads will return a 0, writes are ignored.
LTR: Latency Timer Register
Specifies, in units of PCI bus clocks, the value of the latency timer of the RTL8139D(L).
When the RTL8139D(L) asserts FRAMEB, it enables its latency timer to count. If the RTL8139D(L)
deasserts FRAMEB prior to count expiration, the content of the latency timer is ignored. Otherwise,

MEMAR: This register specifies the base memory address for memory accesses to the RTL8139D(L) operational registers. This
register must be initialized prior to accessing any RTL8139D(L)'s register with memory access.
Bit Symbol Description
31-8 MEM31-8 Base Memory Address: This is set by software to the base address for the operational register map.
7-4 MEMSIZE Memory Size: These bits return 0, which indicates that the RTL8139D(L) requires 256 bytes of

7.4. PCI Power Management Functions
The RTL8139D(L) complies with ACPI (Rev 1.1), PCI Power Management (Rev 1.1), and Device Class
Power Management Reference Specification (V1.0a), such as to support OS Directed Power Management
(OSPM) environment. To support this, the RTL8139D(L) provides the following capabilities:
¾ The RTL8139D(L) can monitor the network for a Wakeup Frame, a Magic Packet, or a Link Change,
and notify the system via PME# when such a packet or event arrives. Then, the whole system can
restore to working state to process the incoming jobs.
¾ The RTL8139D(L) can be isolated from the PCI bus automatically with the auxiliary power circuit
when the PCI bus is in B3 state, i.e. the power on the PCI bus is removed. When the motherboard
includes a built-in RTL8139D(L) single-chip fast Ethernet controller, the RTL8139D(L) can be
disabled when needed by pulling the isolate pin low to 0V.
When the RTL8139D(L) is in power down mode (D1 ~ D3),
♦ The Rx state machine is stopped, and the RTL8139D(L) keeps monitoring the network for wakeup
event such Magic Packet, Wakeup Frame, and/or Link Change, in order to wake up the system.
When in power down mode, the RTL8139D(L) will not reflect the status of any incoming packet in
the ISR register and will not receive any packet into Rx FIFO.
♦ The FIFO status and the packets which are already received into Rx FIFO before entering into power
down mode, are kept by the RTL8139D(L) during power down mode
♦ The transmission is stopped. The action of PCI bus master mode is stopped, too. The Tx FIFO is
kept.
♦ After restoring to a D0 state, the PCI bus master mode continues to transfer the data, which is not yet
moved into Tx FIFO from the last break. The packet that was not transmitted completely last time is
transmitted again.

D3cold_support_PME bit(bit15, PMC register) & Aux_I_b2:0 (bit8:6, PMC register) in PCI configuration
space.
If 9346 D3cold_support_PME bit(bit15, PMC) = 1, the above 4 bits depend on the existence of Aux
power.
If 9346 D3cold_support_PME bit(bit15, PMC) = 0, the above 4 bits are all 0's.
Ex.:
1. If 9346 D3c_support_PME = 1,
¾ Aux. power exists, then PMC in PCI config space is the same as 9346 PMC, i.e. if 9346
PMC = C2 F7, then PCI PMC = C2 F7.
¾ Aux. power is absent, then PMC in PCI config space is the same as 9346 PMC except
the above 4 bits are all 0’s. I.e. if 9346 PMC = C2 F7, the PCI PMC = 02 76.
In this case, if wakeup support is desired when the main power is off, it is
suggested that the 9346 PMC be set to: C2 F7 (RT 9346 default value). It is not
recommended to set the D0_support_PME bit to “1”.
2. If 9346 D3c_support_PME = 0,
¾ Aux. power exists, then PMC in PCI config space is the same as 9346 PMC. I.e. if 9346
PMC = C2 77, then PCI PMC = C2 77.
¾ Aux. power is absent, then PMC in PCI config space is the same as 9346 PMC except
the above 4 bits are all 0’s. I.e. if 9346 PMC = C2 77, the PCI PMC = 02 76.
In this case, if wakeup support is not desired when the main power is off, it is
suggested that the 9346 PMC to be 02 76. It is not recommended to set the
D0_support_PME bit to “1”.
Link Wakeup occurs only when the following conditions are approved,
♦ The LinkUp bit (CONFIG3#4) is set to 1, the PMEn bit (CONFIG1#0) is set to 1, and the
RTL8139D(L) is in isolation state, or the PME# can be asserted in current power state.
♦ The Link status is re-established.
Magic Packet Wakeup occurs only when the following conditions are met:
♦ The destination address of the received Magic Packet matches.
♦ The received Magic Packet does not contain CRC error.
♦ The Magic bit (CONFIG3#5) is set to 1, the PMEn bit (CONFIG1#0) is set to 1, and the
RTL8139D(L) is in isolation state, or the PME# can be asserted in current power state.
♦ The Magic Packet pattern matches, i.e. 6 * FFh + MISC(can be none)+ 16 * DID(Destination ID) in
any part of a valid (Fast) Ethernet packet.
Wakeup Frame event occurs only when the following conditions are met:
♦ The destination address of the received Wakeup Frame matches.
♦ The received Wakeup Frame does not contain a CRC error.
♦ The PMEn bit (CONFIG1#0) is set to 1.
* *
The 8-bit CRC (or 16-bit CRC) of the received Wakeup Frame matches with the 8-bit CRC (or
16-bit CRC) of the sample Wakeup Frame pattern received from the local machine’s OS.

** **
The last masked byte of the received Wakeup Frame matches with the last masked byte of the
sample Wakeup Frame pattern provided by the local machine’s OS. (In Long Wakeup Frame mode,
the last masked byte field is replaced with the high byte of the 16-bit CRC.)
z 8-bit CRC:
This 8-bit CRC logic is use to generate an 8-bit CRC from the masked bytes of the received
Wakeup Frame packet within offset 12 to 75. Software should calculate the 8-bit Power
Management CRC for each specific sample wakeup frame and store the calculated CRC in the
corresponding CRC register for the RTL8139D(L) to check if there is Wakeup Frame packet
coming in.
z 16-bit CRC: (Long Wakeup Frame mode, the mask bytes cover from offset 0 to 127)
Long Wakeup Frame: The RTL8139D(L) also supports 3 long Wakeup Frames. If the range of
mask bytes of the sample Wakeup Frame, passed down by the OS to the driver, exceeds the range
from offset 12 to 75, the related registers of wakeup frame 2 and 3 can be merged to support one
long wakeup frame by setting the LongWF (bit0, CONFIG4). Thus, the range of effective mask
bytes extends from offset 0 to 127. The low byte and high byte of calculated 16-bit CRC should
be put into register CRC2 and LSBCRC2 respectively. The mask bytes (16 bytes) should be store
to register Wakeup2 and Wakeup3. The CRC3 and LSBCRC3 have no meaning in this case and
should be reset to 0. So as the long Wakeup Frame pairs, wakeup frame 4 and 5, wakeup frame 6
and 7. The CRC5, CRC7, LSBCRC5, and LSBCRC7 have no meaning in this case and should be
reset to 0, if the RTL8139D(L) is set to support long Wakeup Frame. In this case, the
RTL8139D(L) support 5 wakeup frames, that are 2 normal wakeup frames and 3 long wakeup
frames.
** last masked byte:
The last byte of the masked bytes of the received Wakeup Frame packet within offset 12 to
75 (in 8-bit CRC mode) should matches with the last byte of the masked bytes of the sample
Wakeup Frame provided by the local machine’s OS.
The PME# signal is asserted only when the following are approved,
The PMEn bit (bit0, CONFIG1) is set to 1.
The PME_En bit (bit8, PMCSR) in PCI Configuration Space is set to 1.
The RTL8139D(L) may assert PME# in current power state, or the RTL8139D(L) is in isolation
state. Refer to PME_Support(bit15-11) of the PMC register in PCI Configuration Space.
Magic Packet, LinkUp, or Wakeup Frame has occurred.
* Writing a 1 to the PME_Status (bit15) of PMCSR register in the PCI Configuration Space will
clear this bit and cause the RTL8139D(L) to stop asserting a PME# (if enabled).
When the RTL8139D(L) is in power down mode, ex. D1-D3, the IO, MEM, and Boot ROM space are all
disabled. After RST# asserted, the power state must be changed to D0 if the original power state is D3 .
cold
There is no hardware enforced delays at RTL8139D(L)’s power state. When in ACPI mode, the
RTL8139D(L) does not support PME from D0 (owing to the setting of PMC register. This setting comes
from EEPROM).

The RTL8139D(L) also supports LAN WAKE-UP function. The LWAKE pin is used to notify the
motherboard to execute wake-up process whenever the RTL8139D(L) receives a wakeup event, such as
Magic Packet.
The LWAKE signal is asserted according the following setting.
LWPME bit (bit4, CONFIG4):
0: The LWAKE is asserted whenever there is wakeup event occurs.
1: The LWAKE can only be asserted when the PMEB is asserted and the ISOLATEB is low.
Bit1 of DELAY byte(offset 1Fh, EEPROM):
0: LWAKE signal is disabled.
1: LWAKE signal is enabled
VPD (Vital Product Data)
Bit 31 of the Vital Product Data (VPD) is used to issue VPD read/write commands, and is also a flag used to
indicate whether the transfer of data between the VPD data register and the 93C46 is completed or not.
1. Write VPD register: (write data to 93C46)
Write the flag bit to a one (at the same time the VPD address is written). When the flag bit is set to zero
by the RTL8139D(L), the VPD data (all 4 bytes) has been transferred from the VPD data register to
93C46.
2. Read VPD register: (read data from 93C46)
Write the flag bit to a zero at the same time the VPD address is written). When the flag bit is set to one by
the RTL8139D(L), the VPD data (all 4 bytes) has been transferred from 93C46 to the VPD data register.

9. Functional Description
9.1. Transmit Operation
The host CPU initiates a transmit by storing an entire packet of data in one of the descriptors in the main
memory. When the entire packet has been transferred to the Tx buffer, the RTL8139D(L) is instructed to
move the data from the Tx buffer to the internal transmit FIFO in PCI bus master mode. When the transmit
FIFO contains a complete packet or is filled to the programmed threshold level, the RTL8139D(L) begins
packet transmission.
9.2. Receive Operation
The incoming packet is placed in the RTL8139D(L)'s Rx FIFO. Concurrently, the RTL8139D(L) performs
address filtering of multicast packets according to its hash algorithms. When the amount of data in the Rx
FIFO reaches the level defined in the Receive Configuration Register, the RTL8139D(L) requests the PCI
bus to begin transferring the data to the Rx buffer in PCI bus master mode.
9.3. Base Line Wander Compensation
The 8139D(L) is ANSI TP-PMD compliant and supports input and Base Line Wander (BLW)
compensation in 100Base-TX mode. The 8139D(L) does not require external attenuation circuitry at its
receive inputs, RD+/-. It accepts TP-PMD compliant waveforms directly, requiring only a 100Ω
termination and a 1:1 transformer.
BLW is the change in the average DC content, over time, of an AC coupled digital transmission over a
given transmission medium. BLW is a result from the interaction between the low frequency components
of a transmitted bit stream and the frequency response of the AC coupling component(s) within the
transmission system. If the low frequency content of the digital bit stream goes below the low frequency
pole of the AC coupling transformers, then the droop characteristics of the transformers will dominate,
resulting in potentially serious BLW. If BLW is not compensated, packet loss can occur.
9.4. Line Quality Monitor
The line quality monitor function is available in 100Base-TX mode. It is possible to determine the amount
of Equalization being used by accessing certain test registers with the DSP engine. This provides a crude
indication of connected cable length. This function allows for a quick and simple verification of the line
quality in that any significant deviation from an expected register value (based on a known cable length)
would indicate that the signal quality has deviated from the expected nominal case.
Single Chip Multifunction 10/100 Ethernet Controller w/Power Management 46 Track ID: JATR-1076-21 Rev. 1.2
RTL8139DL
Datasheet
9.5. Clock Recovery Module
The Clock Recovery Module (CRM) is supported in 100Base-TX mode. The CRM accepts 125Mbps
MLT3 data from the equalizer. The DPLL locks onto the 125Mbps data stream and extracts a 125MHz
recovered clock. The extracted and synchronized clock and data are used as required by the synchronous
receive operations.
9.6. Loopback Operation
Loopback mode is normally used to verify that the logic operations up to the Ethernet cable function
correctly. In loopback mode for 100Mbps, the RTL8139D(L) takes frames from the transmit descriptor and
transmits them up to internal Twister logic.
9.7. Tx Encapsulation
While operating in 100Base-TX mode, the RTL8139D(L) encapsulates the frames that it transmits
according to the 4B/5B code-groups table. The changes of the original packet data are listed as follows:
1. The first byte of the preamble in the MAC frame is replaced with the JK symbol pair.
2. After the CRC, the TR symbol pair is inserted.
9.8. Collision
If the RTL8139D(L) is not in the full-duplex mode, a collision event occurs when the receive input is not
idle while the RTL8139D(L) transmits. If the collision was detected during the preamble transmission, the
jam pattern is transmitted after completing the preamble (including the JK symbol pair).
Single Chip Multifunction 10/100 Ethernet Controller w/Power Management 47 Track ID: JATR-1076-21 Rev. 1.2
RTL8139DL
Datasheet
9.9. Rx Decapsulation
The RTL8139D(L) continuously monitors the network when reception is enabled. When activity is
recognized it starts to process the incoming data.
After detecting receive activity on the line, the RTL8139D(L) starts to process the preamble bytes based on
the mode of operation.
While operating in 100Base-Tx mode, the RTL8139D(L) expects the frame to start with the symbol pair JK
in the first byte of the 8-byte preamble.
The RTL8139D(L) checks the CRC bytes and checks if the packet data ends with the TR symbol pair, if
not, the RTL8139D(L) reports an CRC error RSR.
The RTL8139D(L) reports a RSR error in any of the following cases:
1. In 100Base-Tx mode, one of the following occurs:
a. An invalid symbol (4B/5B Table) is received in the middle of the frame.
RSR bit also sets.
b. The frame does not end with the TR symbol pair.
9.10. Flow Control
The RTL8139D(L) supports IEEE802.3X flow control to improve performance in full-duplex mode. It
detects PAUSE packet to achieve flow control task.
9.10.1. Control Frame Transmission
When the RTL8139D(L) detects that its free receive buffer is less than 3K bytes, it sends a PAUSE packet
with pause_time(=FFFFh) to inform the source station to stop transmission for the specified period of
time. After the driver has processed the packets in the receive buffer and updated the boundary pointer, the
RTL8139D(L) sends the other PAUSE packet with pause_time(=0000h) to wake up the source station to
restart transmission.
9.10.2. Control Frame Reception
The RTL8139D(L) enters a back off state for a specified period of time when it receives a valid PAUSE
packet with pause_time(=n). If the PAUSE packet is received while the RTL8139D(L) is transmitting, the
RTL8139D(L) starts to back off after current transmission completes. The RTL8139D(L) is free to transmit
the next packets when it receives a valid PAUSE packet with pause_time(=0000h) or the backoff
timer(=n*512 bit time) elapses.
Note: The PAUSE operation cannot be used to inhibit transmission of MAC Control frames (e.g. PAUSE
packet). The N-way flow control capability can be disabled, please refer to Section 6, EEPROM (93C46)

HARD TO FIND A BETTER PROVIDER
Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.
Applied Materials
CONSISTENTLY DELIVERS QUALITY SOLUTIONS
Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
