RTL8187SE
Datasheet
Single-Chip Wireless LAN Network Interface Controller
w/PCI Express Interface
1Track ID: JATR-1076-21 Rev. 1.0
1. General Description
The Realtek RTL8187SE is a low-profile highly integrated cost-effective Single-Chip Wireless LAN
network interface controller that integrates a Wireless LAN MAC, a baseband processor, and 2.4GHz RF
onto one chip. It provides a PCI Express bus controller, and full compliance with IEEE 802.11 and IEEE
802.11b/g specifications. It also complies with WMM, 802.11e, and CCX specifications.
To reduce protocol overhead, the RTL8187SE supports Short InterFrame Space (SIFS) burst mode to send
packets back-to-back. A protection mechanism prevents collisions among 802.11b nodes.
Direct Sequence Spread Spectrum (DSSS), Complementary Code Keying (CCK), and Orthogonal
Frequency Division Multiplexing (OFDM) baseband processing are implemented to support all IEEE
802.11b, and 802.11g data rates. Differential phase shift keying modulation schemes, DBPSK and DQPSK
with data scrambling capability, are available, along with complementary code keying to provide data rates
of 1, 2, 5.5, and 11Mbps, with long or short preamble. A high-speed Fast Fourier Transform (FFT)/Inverse
Fast Fourier Transform (IFFT), combined with BPSK, QPSK, 16QAM and 64QAM modulation of the
individual sub-carriers, provides data rates of 6, 9, 12, 18, 24, 36, 48 and 54Mbps, with rate-compatible
punctured convolutional coding with a coding rate of 1/2, 2/3, and 3/4.
An enhanced signal detector, an adaptive frequency domain equalizer, and a soft-decision Viterbi decoder
are built-in to alleviate severe multipath effects. Efficient IQ-imbalance calibration, DC offset, phase noise,
frequency offset, and timing offset compensation reduce radio frequency front-end impairments. Selectable
digital transmit and receive FIR filters are provided to meet the requirements of transmit spectrum masks,
and to reject adjacent channel interference, respectively. Both in the transmitter and receiver,
programmable scaling in the digital domain trades the qµAntization noise against the increased probability
of clipping. Robust signal detection, symbol boundary detection, and channel estimation perform well at
the minimum sensitivity.
The RTL8187SE supports fast receiver Automatic Gain Control (AGC) and antenna diversity functions,
and an adaptive transmit power control function to obtain better performance in the analog portions of the
transceiver. It also has on-chip digital-to-analog converters and analog-to-digital converters for analog I
and Q inputs and outputs, transmit TSSI and receiver RSSI inputs, and transmit and receiver AGC outputs.
RTL8187SE
Datasheet
Single-Chip Wireless LAN Network Interface Controller
w/PCI Express Interface
2Track ID: JATR-1076-21 Rev. 1.0
It supports Advanced Configuration Power management Interface (ACPI), Legacy PCI power management,
and PCI Express power management for modern operating systems that are capable of Operating System
directed Power Management (OSPM). PCI MSI (Message Signaled Interrupt) function and PCI Express
Device Serial Number Capability are also supported.
In addition to the ACPI feature, the RTL8187SE also supports remote wake-up (including AMD Magic
Packet and Microsoft® wake-up frame) in both ACPI and APM environments. To support Wake on
Wireless LAN from a deep power down state (e.g., D3cold, i.e. main power is off and only auxiliary power
exists), the auxiliary power source must be able to provide the needed power. When auxiliary power is
applied and the main power remains off, the RTL8187SE is ready and waiting for a Magic Packet or
wake-up frame to wake the system up.
The RTL8187SE supports an enhanced link list descriptor-based buffer management architecture, which is
an essential part of a design for a modern network interface card. It contributes to lowering CPU utilization.
Also, the RTL8187SE features inter-connect PCI Express technology. PCI Express is a high-bandwidth,
low pin count, serial, interconnect technology that offers significant improvements in performance over
conventional PCI and also maintains software compatibility with existing PCI infrastructure. Support is
also provided for Multiple BSSID, Adjustable fallback steps and fallback rates during auto rate fallback,
TX Power Tracking, Enhanced three-wire mechanism, Parallel Control Interface between Baseband and
RF, and Bluetooth coexistence.
The RTL8187SE keeps network maintenance costs low and eliminates usage barriers. The RTL8187SE is
highly integrated and requires no ‘glue’ logic or external memory.

7. EEPROM (93C46 or 93C56) Contents
The RTL8187SE supports the attachment of an external EEPROM. The 93C46 is a 1Kbit EEPROM
(the 93C56 is a 2Kbit EEPROM). The EEPROM interface provides the ability for the RTL8187SE to read
from, and write data to, an external serial EEPROM device. Values in the external EEPROM allow default
fields in PCI configuration space and IO space to be overridden following an internal power on reset, or
software EEPROM auto-load command. The RTL8187SE will auto-load values from the EEPROM to
these fields in configuration space and IO space. If the EEPROM is not present, the RTL8187SE
initialization uses default values for the appropriate Configuration and Operational Registers. Software can
read and write to the EEPROM using ‘bit-bang’ accesses via the 9346CR Register.
Note: It is suggested to obtain Realtek approval before changing the default settings of the EEPROM.

8. PCI EXPRESSTM
8.1. PCI EXPRESS Bus Interface
The RTL8187SE is compliant with PCI ExpressTM Base Specification Revision 1.1, and runs at 2.5GHz
signaling rate with X1 link width, i.e., one transmit and one receive differential pairs. The RTL8187SE
supports 4 types of PCI Express messages; interrupt messages, error messages, power management
messages, and hot-plug messages. PCI Express lane polarity reversal and link reversal are also supported to
ease PCB layout constraints.
8.1.1. PCI Express Transmitter
The RTL8187SE’s PCI ExpressTM block receives digital data recovered from the WLAN MAC interface
and performs data scrambling with Linear Feedback Shift Register (LFSR) and 8B/10B coding technology
into 10-bit code groups. Data scrambling is used to reduce the possibility of electrical resonance on the link,
and 8B/10B coding technology is used to benefit embedded clocking, error detection, and DC balance by
sacrificing the 25 percent overhead to the system through the addition of 2 extra bits. Then, the data code
groups are passed through its serializer for packet framing to generate 2.5 Gbps serial data and transmitted
onto PCB trace to its upstream device via differential driver.
8.1.2. PCI Express Receiver
The RTL8187SE’s PCI ExpressTM block receives 2.5Gbps serial data from its upstream device to generate
parallel data. The receiver’s PLL circuits are resynchronized to maintain bit and symbol lock. Through
8B/10B decoding technology and data descrambling, the original digital data is able to be recovered and
then the data is passed to the RTL8187SE’s internal WLAN MAC to be transmitted on the air.

(TLP), regardless of the state the Parity Error Enable bit. Default value of this field is 0.
14 SSERR Signaled System Error.
This bit is set when the RTL8187SE sends an ERR_FATAL or ERR_NONFATAL Message, and
the SERR Enable bit in the Command register is 1. Default value of this field is 0.
13 RMABT Received Master Abort.
This bit is set when the RTL8187SE receives a Completion with Unsupported Request
Completion Status. Default value of this field is 0.
12 RTABT Received Target Abort.
This bit is set when the RTL8187SE receives a Completion with Completer Abort Completion
Status. Default value of this field is 0.
11 STABT Signaled Target Abort.
This bit is set when the RTL8187SE completes a Request using Completer Abort Completion
Status. Default value of this field is 0.
10:9 DST1~0 Device Select Timing. Does not apply to PCI Express. Must be hardwired to 0.
8 DPD Data Parity Error Detected.
This bit is set by the RTL8187SE if its Parity Error Enable bit is set and either of the following
two conditions occurs:
- Requestor receives a Completion marked poisoned
- Requestor poisons a write Request
If the Parity Error Enable bit is cleared, this bit is never set. Default value of this field is 0.
7 FBBC Fast Back-To-Back Capable. Does not apply to PCI Express. Must be hardwired to 0.
6 - Reserved.
5 66MHz 66MHz Capable. Does not apply to PCI Express. Must be hardwired to 0.
4 NewCap Capability List.
Indicates the presence of an extended capability list item. Since all PCI Express devices are
required to implement the PCI Express capability structure, this bit must be set to 1.
3 INTSTS Interrupt Status.
This bit reflects the interrupt status of the RTL8187SE.
Unlike ISR bits, this bit is a read-only bit and cannot be reset by writing a 1 to this bit. The only
way to reset this bit is to reset the ISR register.
The setting of the ‘Interrupt Disable’ bit in the Command Register has no effect on the state of
the ‘Interrupt Status’ bit.
Only when the ‘Interrupt Disable’ bit is a 0 and the ‘Interrupt Status’ bit is a 1, will the
RTL8187SE’s Int# signal be asserted.
2:0 - Reserved.

8.6. PCI Power Management Functions
The RTL8187SE is compliant with ACPI (Rev 2.0), PCI Power Management (Rev. 1.2), and Network
Device Class Power Management Reference Specification (V1.0a), such as to support an Operating
System-Directed Power Management (OSPM) environment.
The RTL8187SE can monitor the network for a Wakeup Frame, a Magic Packet, or a Re-LinkOk, and
notify the system via PME# when such a packet or event occurs. Then the system can be restored to a
normal state to process incoming jobs.
When the RTL8187SE is in power down mode (D1 ~ D3):
The Rx state machine is stopped, and the RTL8187SE monitors the network for wakeup events such as
a Magic Packet, Wakeup Frame, and/or Re-LinkOk, in order to wake up the system. When in power
down mode, the RTL8187SE will not reflect the status of any incoming packets in the ISR register and
will not receive any packets into the Rx FIFO buffer.
The FIFO status and packets that have already been received into the Rx FIFO before entering power
down mode are held by the RTL8187SE.
Transmission is stopped. PCI bus master mode is stopped. The Tx FIFO buffer is held.
After restoration to a D0 state, the RTL8187SE transfers data that was not moved into the Tx FIFO
buffer during power down mode. Packets that were not transmitted completely last time are
re-transmitted.
The D3cold_support_PME bit (bit15, PMC register) and the Aux_I_b2:0 bits (bit8:6, PMC register) in PCI
configuration space depend on the existence of Aux power (bit15, PMC) = 1.
If EEPROM D3cold_support_PME bit (bit15, PMC) = 0, the above 4 bits are all 0’s.
Example:
If EEPROM D3c_support_PME = 1:
If aux. power exists, then PMC in PCI config space is the same as EEPROM PMC
(if EEPROM PMC = C3 F7, then PCI PMC = C3 F7)
If aux. power is absent, then PMC in PCI config space is the same as EEPROM PMC except the above
4 bits are all 0’s (if EEPROM PMC = C3 F7, then PCI PMC = 03 76)
In the above case, if wakeup support is desired when main power is off, it is suggested that the EEPROM
PMC be set to C3 F7 (Realtek EEPROM default value).

If EEPROM D3c_support_PME = 0:
If aux. power exists, then PMC in PCI config space is the same as EEPROM PMC
(if EEPROM PMC = C3 77, then PCI PMC = C3 77)
If aux. power is absent, then PMC in PCI config space is the same as EEPROM PMC except the above
4 bits are all 0’s (if EEPROM PMC = C3 77, then PCI PMC = 03 76)
In the above case, if wakeup support is not desired when main power is off, it is suggested that the
EEPROM PMC be set to 03 76.
Magic Packet Wakeup occurs only when the following conditions are met:
The destination address of the received Magic Packet is acceptable to the RTL8187SE, e.g. a broadcast,
multicast, or unicast packet addressed to the current RTL8187SE adapter.
The received Magic Packet does not contain a CRC error.
The Magic bit (CONFIG3#5) is set to 1, the PMEn bit (CONFIG1#0) is set to 1, and the PME# can be
asserted in the 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 WLAN packet.
A Wakeup Frame event occurs only when the following conditions are met:
The destination address of the received Wakeup Frame is acceptable to the RTL8187SE, e.g. a
broadcast, multicast, or unicast address to the current RTL8187SE adapter.
The received Wakeup Frame does not contain a CRC error.
The PMEn bit (CONFIG1#0) is set to 1.
The 16-bit CRC* of the received Wakeup Frame matches the 16-bit CRC* of the sample Wakeup Frame
pattern given by the local machine’s OS. Or, the RTL8187SE is configured to allow direct packet
wakeup, e.g. a broadcast, multicast, or unicast network packet.
*16-bit CRC: The RTL8187SE supports two normal wakeup frames (covering 64 mask bytes from offset 0 to
63 of any incoming network packet) and three long wakeup frames (covering 128 mask bytes from offset 0
to 127 of any incoming network packet).

The PME# signal is asserted only when the following conditions are met:
The PMEn bit (bit0, CONFIG1) is set to 1.
The PME_En bit (bit8, PMCSR) in PCI Configuration Space is set to 1.
The RTL8187SE may assert PME# in the current power state or in isolation state, depending on the
PME_Support (bit15-11) setting of the PMC register in PCI Configuration Space.
A Magic Packet, LinkUp, or Wakeup Frame has been received.
Note: Writing a 1 to the PME_Status (bit15) of the PMCSR register in the PCI Configuration Space clears
this bit and causes the RTL8187SE to stop asserting a PME# (if enabled).
When the device is in power down mode, e.g. D1~D3, the IO, and MEM spaces are all disabled. After a
RST# assertion, the device’s power state is restored to D0 automatically if the original power state was
D3cold. There is no hardware delay at the device’s power state transition. When in ACPI mode, the device
does not support PME (Power Management Enable) from D0 (this is the Realtek default setting of the PMC
register auto-loaded from EEPROM). The setting may be changed from the EEPROM, if required. The
RTL8187SE also supports the legacy LAN WAKE-UP function. The LWAKE pin is used to notify legacy
motherboards to execute the wake-up process whenever the device receives a wakeup event, such as Magic
Packet.

9. Functional Description
9.1. Transmit & Receive Operations
The RTL8187SE supports a descriptor-based buffer management that will significantly lower host CPU
utilization. The RTL8187SE supports an infinite number of consecutive transmit descriptors, and 64
consecutive receive descriptors, in memory.
There may be a maximum of five descriptor rings. Transmit descriptor rings consist of one beacon transmit
descriptor ring, one high priority descriptor ring, one normal priority descriptor ring, and one low priority
descriptor ring. Each transmit descriptor ring may consist of an infinite number of 8-double-word
consecutive descriptors, and the receive descriptor array may consist of up to sixty-four 4-double-word
consecutive descriptors. The start address of each descriptor group should be in 256byte alignment.
Software must pre-allocate enough buffers and configure all descriptor rings before transmitting and/or
receiving packets.
9.1.1. Transmit
The following describes what the Tx descriptor may look like, depending on different states in each Tx
descriptor.

Note1: Measurement taken from single ended waveform.
Note2: Measurement taken from differential waveform.
Note3: Measured from -150 mV to +150 mV on the differential waveform (derived from REFCLK+ minus REFCLK-). The
signal must be monotonic through the measurement region for rise and fall time. The 300 mV measurement window is
centered on the differential zero crossing.
Note4: Measured at crossing point where the instantaneous voltage value of the rising edge of REFCLK+ equals the falling
edge of REFCLK-.
Note5: Refers to the total variation from the lowest crossing point to the highest, regardless of which edge is crossing.
Refers to all crossing points for this measurement.
Note6: Defines as the absolute minimum or maximum instantaneous period. This includes cycle to cycle jitter, relative PPM
tolerance, and spread spectrum modulation.
Note7: Defined as the maximum instantaneous voltage including overshoot.
Note8: Defined as the minimum instantaneous voltage including undershoot.
Note9: Defined as the total variation of all crossing voltages of Rising REFCLK+ and Falling REFCLK-. This is the
maximum allowed variance in VCROSS for any particular system.
Note10: Refer to Section 4.3.2.1 of the PCI Express Base Specification, Revision 1.1 for information regarding PPM
considerations.
Note11: System board compliance measurements must use the test load card described in Figure16. REFCLK+ and
REFCLK- are to be measured at the load capacitors CL. Single ended probes must be used for measurements requiring
single ended measurements. Either single ended probes with math or differential probe can be used for differential
measurements. Test load CL = 2 pF.
Note12: TSTABLE is the time the differential clock must maintain a minimum ±150 mV differential voltage after rising/falling
edges before it is allowed to droop back into the VRB ±100 mV differential range. See Figure 15.
Note13: PPM refers to parts per million and is a DC absolute period accuracy specification. 1 PPM is 1/1,000,000th of
100.000000 MHz exactly or 100 Hz. For 300 PPM then we have a error budget of 100 Hz/PPM * 300 PPM = 30 kHz. The
period is to be measured with a frequency counter with measurement window set to 100 ms or greater. The ±300 PPM
applies to systems that do not employ Spread Spectrum or that use common clock source. For systems employing Spread
Spectrum there is an additional 2500 PPM nominal shift in maximum period resulting from the 0.5% down spread resulting
in a maximum average period specification of +2800 PPM
Note14: Matching applies to rising edge rate for REFCLK+ and falling edge rate for REFCLK-. It is measured using a ±75
mV window centered on the median cross point where REFCLK+ rising meets REFCLK- falling. The median cross point is
used to calculate the voltage thresholds the oscilloscope is to use for the edge rate calculations. The Rise Edge Rate of
REFCLK+ should be compared to the Fall Edge Rate of REFCLK-, the maximum allowed difference should not exceed
20% of the slowest edge rate.
Note15: Refer to PCI Express Card Electromechanical Specification, rev.1.1, for correct measurement environment setting
of each parameter.
