`INTRODUCTION
`The PCnet™-FASTboard is an advanced PC network interface adapter card targeted for
`the Ethernet-PCI adapter card market. It is based on the Am79C971 PCnet-FASTdevice,
`a single-chip 32-bit full-duplex, 10/100-Mbps highly integrated Ethernet system solution.
`Designed to address high performance system applications, the flexible bus master archi(cid:173)
`tecture provides high data throughput in the system and low CPU and system bus utilization .
`The PCnet-FASTboard supports the PCI Specification (Rev. 2.1 ), jumperless bus and
`media configuration , and driver software compatible with the existing PCnet family of driv(cid:173)
`ers.
`
`This manual provides a complete description of the PCnet-FASTboard, with sections
`covering the functional description of each building block, the setup and installation of the
`board, and the hardware specification .

`
`BOARD DESCRIPTION
`The PCnet-FAST board is a 10/ 1 00-Mbps PCI network interface card. The Ethernet con(cid:173)
`nection is implemented through the single RJ-45 jack which is connected to an external
`1 0/1 00 TX transceiver. The transceiver is connected to the PC net- FAST controller through
`the integrated Media Independent Interface (Mil). Due to the high integration of the PC net(cid:173)
`FAST device, very few external parts are needed. The PCnet- FAST evaluation board pro(cid:173)
`vides the remote boot capability via an EPROM on the FLASH device. In addition, SRAMs
`may be added to optimize performance. In most applications, two 15-ns 32x8 SRAMs are
`sufficient to satisfy the buffer requirement.
`
`The following diagram illustrates the implementation of the PCnet- FASTboard.

`
`ETHERNET NODE CONTROLLER
`The single-chip Am79C971 PCnet-FAST Ethernet solution is a highly integrated solution
`that contains a Bus Interface Unit (BIU), a DMA buffer management unit, an ISO/IEC
`8802-3 and ANSI/IEEE 802.3-compliant Media Access Control (MAC) function, a flexible
`buffer architecture with an SRAM-based FIFO extension for support up to 128 Kbytes of
`external frame buffering, optional remote boot PROM/FLASH, integrated 10BASE-T and
`10BASE-2/5 (AUI ) physical layer interface, and an ANSI/IEEE 802.3-compliant Media In(cid:173)
`dependent Interface (Mil).

`
`LOCAL BUS INTERFACE
`The PCnet-FASTboard implements the local bus interface to the Peripheral Components
`Interconnect (PCI) revision 2.1 specification through the Am79C97 1 chip. The BIU in the
`chip is designed to operate as a PCI bus master during normal operations, and some slave
`1/0 accesses to the controller are required in normal operation as well. Initialization of the
`Ethernet controller is achieved through a combination of PCI Configuration Space ac(cid:173)
`cesses, bus slave accesses, bus master accesses, and an optional read of a serial EE(cid:173)
`PROM that is performed by the controller.
`
`ETHERNET INTERFACE
`The Ethernet interface for the PCnet-FAST board is achieved through the single RJ-45
`jack. The RJ-45 jack is connected to an external 1 0/ 1 00-Mbps transceiver connected to
`the PCnet-FAST controller through the integrated Mil.
`
`EXPANSION BOOT ROM/FLASH
`The PCnet-FASTboard can accommodate up to 256K bits of Boot ROM Code. An external
`latch is used to allow Boot ROM Address and Data Latching when AS_EBOE is asserted.
`The PCnet-FASTboard supports EPROM or Flash as an Expansion boot ROM device.
`Both are configured using the same methods and operate the same way.
`
`SRAM INTERFACE
`When using the controller in a 1 00-Mbps environment, additional frame buffering capability
`is provided by a 16-bit w ide SRAM interface which provides high performance and high
`latency tolerance on the system bus and network. The controller can use up to 128 Kbytes
`of SRAM as an extension of its dual transmit and receive FIFOs. When no SRAM is used,
`the Am79C97 1 controller's FIFOs are programmed to bypass the SRAM interface.
`SERIAL EEPROM INTERFACE
`The PCnet-FASTboard stores the unique IEEE physical address and bus configuration of
`each node in the serial EEPROM. Once pow ered up, the Am79C971 chip automatically
`detects the presence of the EEPROM and reads the 32 words stored in it through the Mi(cid:173)
`croWire interface protocol. For details of the MicroWire interface, refer to the Am79C971
`data sheet. The interface also supports the W RITE operation to the EEPROM.
`
`AUTO-NEGOTIATION CONTROL
`The PCnet-FASTboard implements the Auto-Negotiation standard per the IEEE 802.3
`specification for the 10BASE-T Media Attachment Unit (MAU) and the M il port.
`Auto-Negotiation automatically configures the link between two link partners through the
`Fast Link Pulse. The Fast Link Pulse is made up of a train of 17 clocks alternating with the
`16 data fields for a total of 33 pulses. The two link partners send information in the 16 data
`positions between themselves. Both sides look to see w hat is possible and then connect
`at the greatest speed and capability (without any software support) as show n in the table
`below. The Auto-Negotiation capabilities for the PCnet-FASTboard are as follows:

`
`BOARD CONFIGURATION
`Configuration of the 1/0 base address and the interrupt channel is automatic upon power
`up, without any hardware jumpers. The system BIOS routine is responsible for assigning
`the 1/0 base address and binding the appropriate interrupt channels to the PCnet-FAST
`board. One may find out what the 1/0 base assignment and the interrupt channel binding
`through the AMD installation software and configuration utility. For more detailed informa(cid:173)
`tion on this utility, refer to the PCnet Family Network Driver Installation Guide.
`
`10/100BASE·T PHYSICAL CONNECTIONS
`A Data Terminal Equipment (DTE) system with the installed PCnet-FASTboard can
`connect to an Ethernet network using the on-board RJ-45 jack for either 1 OBASE-T or
`1 OOBASE-TX connection. Figure 3-1 illustrates a typical network configuration for the net(cid:173)
`work using the PCnet-FASTboard.

`
`PCIINTERFACE
`The Am79C971 chip on the PCnet-FASTboard contains the interface logic to the PCI bus.
`Connections to the PCI bus are straightforward in that there is no external glue logic on the
`PCnet-FASTboard, thus making the PCnet-FASTboard fully compliant to the PC I loading
`and trace length specifications.
`
`The types of PCI cycles supported on the PCnet- FASTboard are as follows:
`
`• Master Memory Read
`• Master Memory Write
`• Master Memory Read Line
`• Slave Configuration Read
`• Slave Configuration Write
`• Slave 1/0 Read
`• Slave 1/0 Write
`
`The first three types are the Master cycles that the Am79C971 chip uses to transfer data
`across the PCI bus. The Am79C971 chip owns and controls the address/data bus after its
`request is acknowledged by the system arbiter. If there are two or less double words to
`read, the Am79C971 chip uses the Memory Read cycle; if there are more than two double
`words to read, the Am79C971 chip uses the Memory Read Line cycle. All Master cycles
`also support the four types of slave termination schemes specified in the PCI Revision 2.1
`specification.
`
`4.2
`
`The last four types are the Slave cycles that the host CPU uses to access configuration
`and register information in the Am79C971 chip.
`
`1/0 BASE ADDRESS AND INTERRUPT
`In a PCI system, the 1/0 base address and the interrupt channel that the PCnet- FAST
`board uses are assigned by the POST routine. Software drivers determine the 1/0 base
`address and the interrupt channel assigned to the PCnet-FAST board by reading the PCI
`configuration space of the device.
