General Description The Realtek RTL8187B is a low-profile highly integrated cost-effective Wireless LAN USB 2.0 network interface controller that integrates a USB 2.0 PHY, SIE (Serial Interface Engine), 8051 MCU, a Wireless LAN MAC, and a Direct Sequence Spread Spectrum/OFDM baseband processor onto one chip. It provides USB high speed (480Mbps), and full speed (12Mbps), and supports 9 endpoints for transfer pipes. To reduce protocol overhead, the RTL8187B supports Short InterFrame Space (SIFS) burst mode to send packets back-to-back. A protection mechanism prevents collisions among 802.11b nodes. The RTL8187B fully complies with IEEE 802.11a/b/g, WMM, 802.11e, and CCX specifications. To reduce protocol overhead, the RTL8187B 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 802.11a, 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 receiver 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 quantization noise against the increased probability of clipping. Robust signal detection, symbol boundary detection, and channel estimation perform well at the minimum sensitivity. The RTL8187B 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. The RTL8187B keeps network maintenance costs low and eliminates usage barriers. The RTL8187B is highly integrated and requires no glue logic or external memory. The installation for antenna is fixed as vertical polarization. Wireless LAN Network Interface Controller 1 Track ID: JATR-1076-21 Rev. 1.0 2. Features

Control Transfer Control transfers configure and send commands to a device. Because they are so important, they employ extensive USB error checking. The host reserves a portion of each USB frame for control transfers. Control transfers consist of two or three stages. The SETUP stage contains eight bytes of USB control data. An optional DATA stage contains more data, if required. The STATUS stage allows the device to indicate successful completion of a control operation. 7.2. Bulk Transfer Bulk data is bursty, traveling in packets of 8, 16, 32, or 64 bytes at full speed, or at 512 bytes at high speed. Bulk data has guaranteed accuracy due to an automatic retry mechanism for erroneous data. The host schedules transmission of bulk packets when there is available bus time.

The 93C46 is a 1Kbit EEPROM (the 93C56 is a 2Kbit EEPROM). The EEPROM interface provides the ability for the RTL8187B to read from, and write data to, an external serial EEPROM device. If the EEPROM is not present, the RTL8187B initialization uses default values for the Operational Registers. Software can read and write to the EEPROM using bit-bang accesses via the 9346CR Register. Although it is actually addressed by words, its contents are listed below by bytes for convenience. After the initial power on or auto-load command in the 9346CR, the RTL8187B performs a series of EEPROM read operations from the 93C46 (93C56). Note: It is suggested to obtain Realtek approval before changing the default settings of the EEPROM. Table 24.

USB Packet Buffering The RTL8187B incorporates two independent FIFOs for transferring data to/from the system interface and from/to the network. The FIFOs provide temporary storage of data, freeing the host system from the real-time demands of the network. The way in which the FIFOs are emptied and filled is controlled by the FIFO threshold values in the Receive Configuration registers. These values determine how full or empty the FIFOs must be before the device requests the bus. Once the RTL8187B requests the bus, it will attempt to empty or fill the FIFOs as allowed by the respective MXDMA settings in the Transmit Configuration and Receive Configuration registers. 10.1. Transmit Buffer Manager The buffer management scheme used on the RTL8187B allows quick, simple, and efficient use of the frame buffer memory. The buffer management scheme uses separate buffers and descriptors for packet information. This allows effective transfers of data to the transmit buffer manager by simply transferring the descriptor information to the transmit queue. The Tx Buffer Manager DMAs packet data from system memory and places it in the 3.5KB transmit FIFO, and pulls data from the FIFO to send to the Tx MAC. Multiple packets may be present in the FIFO, allowing packets to be transmitted with Short InterFrame (SIF) space. Additionally, once the RTL8187B requests the bus, it will attempt to fill the FIFO as allowed by the MXDMA setting. The Tx Buffer Manager process also supports priority queuing of transmit packets. It handles this by drawing from two separate descriptor lists to fill the internal FIFO. If packets are available in the high priority queues, they will be loaded into the FIFO before those of low priority. 10.2. Receive Buffer Manager The Rx Buffer Manager uses the same buffer management scheme as used for transmits. The Rx Buffer Manager retrieves packet data from the Rx MAC and places it in the 4KB receive data FIFO, and pulls data from the FIFO for DMA to system memory. The receive FIFO is controlled by the FIFO threshold value in RXFTH. This value determines the number of long words written into the FIFO from the MAC unit before a DMA request for system memory occurs. Once the RTL8187B gets the bus, it will continue to transfer the long words from the FIFO until the data in the FIFO is less than one long word, or has reached the end of the packet, or the max DMA burst size is reached, as set in MXDMA. 10.3. Packet Recognition The Rx packet filter and recognition logic allows software to control which packets are accepted, based on destination address and packet type. Address recognition logic includes support for broadcast, multicast hash, and unicast addresses. The packet recognition logic includes support for WOL and programmable pattern recognition.

11.3. Loopback Operation Loopback mode is normally used to verify that the logic operations have performed correctly. In loopback mode, the RTL8187B takes frames from the transmit descriptor and transmits them up to internal Rx logic. The loopback function does not apply to an external PHYceiver. 11.4. Tx Encapsulation (With RTL8187B Internal Baseband Processor) When operating in Tx mode, the RTL8187B encapsulates the frames that it transmits according to the Differential Binary Phase Shift Keying (DBPSK) for 1Mbps, Differential Quaternary Phase Shift Keying
(DQPSK) for 2Mbps, and Complementary Code Keying (CCK) for 5.5Mbps and 11Mbps modulators. The changes to the original packet data are as follows:
1. The PLCP preamble is always transmitted as the DBPSK waveform and used by the receiver to achieve initial PN synchronization. 2. The PLCP header can be configured to be either DBPSK or DQPSK and includes the necessary data fields of the communications protocol to establish the physical layer link. 3. The MAC frame can be configured for DBPSK, DQPSK, or CCK. Wireless LAN Network Interface Controller 29 Track ID: JATR-1076-21 Rev. 1.0 RTL8187B Datasheet 11.5. Rx Decapsulation (With RTL8187B Internal Baseband Processor) The RTL8187B 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 channel, the RTL8187B starts to process the PLCP preamble and header based on the mode of operation. The RTL8187B checks CRC16 and CRC32, then reports if CRC16 or CRC32 has errors. When using the 40-bit WEP and 104-bit WEP module for decryption, the RTL8187B also checks the Integrity Check Value
(ICV) and reports if the ICV has errors. 11.6. QoS Functions The RTL8187B supports WMM, WMM Scheduled Access, and IEEE 802.11e functions. 11.7. Contention-based Admission Control Functions Refer to Section 9.9.3 of the IEEE 802.11e specification for greater detail. The ATL (Admitted Time Limit) is a statically set value which determines the maximum transmission time a class can have. Software keeps track of admitted time per access that requires admission control. Upon receipt of a successful response frame, the non-AP QSTA adds the admitted time variable for the specified EDCAF to the value contained in the Medium Time field of the TSPEC element. The non-AP QSTA then starts a five-second timer. The non-AP QSTA shall update the value of used time:
A. At five second intervals used_time = max ((used_time-admitted_time), 0) B. After each successful or unsuccessful MPDU (re)transmission attempt, used_time = used_time + MPDUExchangeTime If the used_time reaches or exceeds the admitted time value, the corresponding EDCAF sets the corresponding bit in the ACM_CONTROL register to 1. The corresponding EDCAF may then choose to temporarily replace the EDCA parameters for the EDCAF with those specified for an access category of lower priority, if no admission control is required for those access categories. Wireless LAN Network Interface Controller 30 Track ID: JATR-1076-21 Rev. 1.0 RTL8187B Datasheet 11.8. Duration Field Processing The RTL8187B supports three modes of duration field processing (selected via the DurProcMode bit in each AC_XX_TXOPQueued register). Mode 0: Software takes full control of duration field processing. MAC has nothing to do with it. Mode 1: DMA reads the 2-byte DURATION value in the TX descriptor and adds it to the AC_XX_TXOPQueued register. Mode2: Hardware accumulates all the requested duration values of each EDCAF data queue and each EDCAF FIFO and writes the value to each corresponding AC_XX_TXOPQueued register. In Mode1 and Mode2, MAC decreases the value in the AC_XX_TXOPQueued register each time an EDCAF packet is transmitted. 11.9. LED Functions The RTL8187B supports 2 LED signals in 4 configurable operation modes. The following sections describe the different LED actions. 11.9.1. Link Monitor The Link Monitor senses the link integrity. Whenever link status is established, the specific link LED pin is driven low. 11.9.2. Infrastructure Monitor The Infrastructure Monitor senses the link integrity of an Infrastructure network. Whenever Link OK in Infrastructure network status is established, the specific Infrastructure LED pin is driven low.
