track id: jatr-1076-21 rev. 1.2 1. general description the realtek rtl8139d(l) is a highly integrated and co st-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 dir ected 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 rema ins off, the rtl8139d(l) is ready and is waiting for the magic packet or link change to wake the syst em up. also, the lwake pin provides 4 different output signals including active high, active low, positive pul se, 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-dow n, that is, the analog part of the rtl8139d(l) can be shut down temporarily according to user requi rement or when the rtl 8139d(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 al so 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 a nd 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 impr ove 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. rtl8139dl datasheet single chip multifunction 10/100 ethern et controller w/power management 2 track id: jatr-1076-21 rev. 1.2 2. features ? 100 pin

jatr-1076-21 rev. 1.2 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 (pme#) o/d 57 power management event: open drain, active low. used by the rtl8139d(l) to request a change in its current power management state and/or to indicate that a pow er management event has occurred. isolateb (isolate#) i 74 isolate pin: active low. used to isolate the rtl8139d(l) from the pci 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, 1,3-5,8-10,23-30,33, 36-38,41,42,44,45 pci address and data multiplexed pins. pins ad31-24 are shared with bootrom data pins, while ad16-0 are 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 frequenc y 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 asse rted 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 single chip multifunction 10/100 ethern et controller w/power management 5 track id: jatr-1076-21 rev. 1.2 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 th at 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. da ta 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 (detect ed 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. rs tb must be held for a minimum of 120 ns. rtl8139dl datasheet single chip multifunction 10/100 ethern et controller w/power management 6 track id: jatr-1076-21 rev. 1.2 4.3. eeprom interface symbol type

config1 register is set. the rtl8139d(l) will assert the pmeb signal to wakeup the operating system when the ma gic 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 p acket 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 multi cast 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 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55 66 + 11 22 33 44 55

(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 wake up 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 ma sk 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 wa keup frame 2 and 3 can be merged to support one long wakeup frame by setting the longwf (bit0, conf ig4). 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 respectiv ely. 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 fr ame 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 ar e 2 normal wakeup frames and 3 long wakeup frames. ** last masked byte: the last byte of the masked byt es of the received wakeup frame packet within offset 12 to 75 (in 8-bit crc mode) should matches with the la st 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, ?

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 rtl 8139d(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). rtl8139dl datasheet single chip multifunction 10/100 ethern et controller w/power management 44 track id: jatr-1076-21 rev. 1.2 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 vp d 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 b een 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 a ddress 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. rtl8139dl datasheet single chip multifunction 10/100 ethern et controller w/power management 45 track id: jatr-1076-21 rev. 1.2 8. block diagram mii interface interrupt control logic fifo transmit/ receive logic interface early interrupt control logic fifo control logic packet type discriminator power control logic pci interface + register packet length register early interrupt threshold register eeprom interface led driver rxin+ rxin- txo+ txo - rxc 25m 25m txc 25m txd rxd td+ variable current 3 level driver master ppl adaptive equalizer peak detect 3 level comparator control voltage mlt-3 to nrzi serial to parrallel ck data slave pll parrallel to serial baseline wander correction 5b 4b decoder data alignment descrambler 4b 5b encoder scrambler 10/100 half/full switch logic 10/100m auto-negotiation control logic manchester coded waveform 10m output waveform shaping data recovery receive low pass filter rxd rxc 25m txd txc 25m txd10 txc10 rxd10 rxc10 link pulse mii interface 10m 100m pci interface mac phy transceiver 2nd pci device rtl8139dl datasheet single chip multifunction 10/100 ethern et controller w/power management 46 track id: jatr-1076-21 rev. 1.2 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 tr ansmit 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 ha sh algorithms. when the amount of data in the rx fifo reaches the level defined in the receive conf iguration 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 s upports 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 co mpliant waveforms directly, requiring only a 100 ? 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 th e interaction between the low frequency components of a transmitted bit stream and the frequency res ponse 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 transforme rs, 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 100bas e-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 allo ws for a quick and simple verification of the line quality in that any significant deviation from an exp ected register value (based on a known cable length) would indicate that the signal quality has deviated from the expected nominal case. rtl8139dl datasheet single chip multifunction 10/100 ethern et controller w/power management 47 track id: jatr-1076-21 rev. 1.2 9.5. clock recovery module the clock recovery module (crm) is supporte d in 100base-tx mode. the crm accepts 125mbps mlt3 data from the equalizer. the dpll locks ont o the 125mbps data stream and extracts a 125mhz recovered clock. the extracted and synchronized cloc k and data are used as required by the synchronous receive operations. 9.6. loopback operation loopback mode is normally used to verify that th e 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 co llision 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). rtl8139dl datasheet single chip multifunction 10/100 ethern et controller w/power management 48 track id: jatr-1076-21 rev. 1.2 9.9. rx decapsulation the rtl8139d(l) continuously monitors the networ k when reception is enabled. when activity is recognized it starts to process the incoming data. after detecting receive activity on th e 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) exp ects 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 p acket data ends with the tr symbol pair, if not, the rtl8139d(l) reports an crc error rsr. the rtl8139d(l) reports a rsr rtl8139dl datasheet single chip multifunction 10/100 ethern et controller w/power management 49 track id: jatr-1076-21 rev. 1.2 9.11. led functions 9.11.1. 10/100mbps link monitor the link monitor senses the link integrity or if a station is down. 9.11.2. led_rx in 10/100 mbps mode, the led function is the same as the rtl8139c(l). receiving packet?
