DP83815DVNG - 10/100 Ethernet PCI Controller | Texas Instruments
Артикул: DP83815DVNG ✓ АктивенDP83815DVNG Обзор
An Ethernet media access controller, or MAC, manages frame transmission and reception between a computer system and the physical network layer. The DP83815 integrates that MAC function with a 10BASE-T/100BASE-TX PHY, while its PCI interface provides host communication through bus mastering. Packet descriptors and data are transferred directly by the controller, reducing processing load on the host CPU and improving throughput in network-intensive systems.
The device implements the PCI version 2.2 interface at 33 MHz and includes power-management support. It supports IEEE 802.3 Ethernet operation, 10/100 Base-T/TX connectivity, virtual LAN and long-frame support, and IEEE 802.3x full-duplex flow control. These features make it suitable for legacy PCI systems, embedded control platforms, industrial equipment, and retrofitted personal computers that require a dedicated Ethernet controller rather than a modern software MAC.
Electrical operation is centered on a 3 V to 3.6 V supply range, with a reported supply current of approximately 170 mA. The commercial-temperature variant operates from 0C to +70C. Because the controller combines digital PCI processing with analog PHY functions, the layout should keep the Ethernet differential pairs controlled and provide the supply and decoupling network recommended by the manufacturer.
The DP83815DVNG is primarily intended for PCI-based systems. It is not a USB Ethernet controller, and it cannot directly replace devices using a PCI Express, USB, or RMII interface without board-level redesign. Its integrated PHY and bus-mastering architecture make it useful when a design requires autonomous packet handling and reduced host-CPU involvement.
This page consolidates the verified manufacturer and distributor specifications, compares documented same-family alternatives, and highlights the practical constraints engineers should check before reusing a legacy PCI motherboard design. Pricing and availability must be confirmed against current distributor listings because the retrieved source data did not provide a numeric price schedule.

Типичное применение
DP83815DVNG подходит для 6 применениеs: Legacy PCI Desktop Motherboard Ethernet, Industrial PCI Adapter Card, Embedded PCI Control System, VLAN-Enabled Network Management Node, Legacy PCI Network Adapter Upgrade, Retrofit Server or Industrial PC Ethernet Port.
Legacy PCI Desktop Motherboard Ethernet
The DP83815DVNG fits a PCI-based desktop motherboard that needs dedicated 10/100 Mb/s networking. Its PCI version 2.2 interface operates at 33 MHz, while bus mastering transfers packet descriptors and data directly from system memory, reducing the processing burden on the host CPU. The integrated 10BASE-T/100BASE-TX PHY eliminates a separate physical-layer device and keeps the board area manageable. In a new motherboard layout, the engineer must still allocate a 144-LQFP footprint, provide a 3 V to 3.6 V rail, and route the Ethernet differential pairs away from high-speed digital signals.
Рекомендуется
Industrial PCI Adapter Card
The DP83815DVNG is appropriate for an industrial PCI network adapter intended to add legacy Ethernet connectivity to a control PC or embedded chassis. The combination of an integrated MAC and PHY supports 10BASE-T and 100BASE-TX operation, while IEEE 802.3x full-duplex flow control provides link-level pause-frame behavior when traffic becomes congested. Its bus-mastering architecture allows frames to move without CPU copying on every packet. Practical deployment is limited to systems that retain a PCI connector and mechanical space for the 144-LQFP package.
Рекомендуется
Embedded PCI Control System
The DP83815DVNG can provide network access in an embedded system whose host bus is PCI rather than USB or PCI Express. Its 10/100 Mb/s rate is sufficient for supervisory traffic, configuration transfer, diagnostics, and low-volume control data. Because the controller performs bus-mastered packet transfers, the host processor can devote more cycles to real-time control tasks. The 0C to +70C operating range identifies this version as a commercial-temperature part, so it should not be assumed suitable for extended industrial or automotive ambient conditions without additional qualification.
Рекомендуется
VLAN-Enabled Network Management Node
The DP83815DVNG's virtual LAN support makes it useful in a managed legacy PCI node that must separate traffic by VLAN. IEEE 802.3x flow control adds another layer of usefulness on shared or congested links, while long-frame support broadens the range of accepted frame sizes. The controller's integrated PHY avoids the need for a separate 10/100 transceiver. Designers should confirm the host driver and network configuration support these features, because the controller alone does not determine how VLAN tags are created, filtered, or managed by the operating system.
Рекомендуется
Legacy PCI Network Adapter Upgrade
A repair or modernization platform can use the DP83815DVNG to recreate a 10/100 Mb/s Ethernet function on a PCI adapter board. The controller supports the IEEE 802.3 Ethernet standard, bus mastering, and power-management functions expected by PCI version 2.2 systems. Its 170 mA reported supply current makes supply design and thermal review necessary, while the 144-LQFP package requires careful handling and a conservative land pattern. Before assembly, engineers should verify the exact revision's pin assignments, strap resistors, crystal or clock network, and PHY magnetics from the manufacturer datasheet.
Рекомендуется
Retrofit Server or Industrial PC Ethernet Port
The DP83815DVNG is useful for adding or repairing 10/100 Mb/s networking on older PCI-based servers and industrial PCs that lack modern USB or PCI Express Ethernet ports. Because the host interface is PCI version 2.2 at 33 MHz, the solution preserves compatibility with an existing expansion architecture instead of forcing a connector and host-interface redesign. Bus mastering helps maintain host responsiveness, and the integrated PHY simplifies the board-level bill of materials. It is most practical for brownfield maintenance, where reusing the original motherboard layout and validated driver stack is more valuable than adopting a newer Ethernet controller.

Заметки по проектированию
Treat the integrated PHY as a sensitive analog subsystem even though the controller also contains a digital PCI bus. Route the 10BASE-T and 100BASE-TX differential pairs as a controlled-impedance pair, keep them short, and avoid routing them beneath or immediately beside high-speed PCI signals. The verified source set does not contain the complete reference schematic or exact magnetics requirements, so the manufacturer datasheet layout, component list, and reference design must be followed without substitution.
Design the DP83815DVNG supply around the documented 3 V to 3.6 V operating range and approximately 170 mA supply current. Use the manufacturer's recommended local decoupling at the device pins and verify that supply ripple and startup behavior remain acceptable with the actual PHY magnetics and external clock network. Estimated dissipation cannot be stated reliably without a confirmed operating voltage, current under the design load, and package thermal data; use those datasheet values before sizing copper or considering a heatsink.
Do not treat every 144-LQFP PCI Ethernet controller as a drop-in replacement. A package match does not guarantee identical strap pins, reset polarity, clock requirements, power-management behavior, interrupt routing, or PHY support-net assignments. For DP83815DVNG alternatives, compare the complete pin tables and schematics, then verify that unused pins, strap resistors, wake-up behavior, and the host driver remain compatible. This is especially important for the DP83816AVNG, for which the verified data establishes package similarity but not full pin equivalence.
Информация о соответствии
The verified cross-reference description identifies DP83815DVNG/NOPB as lead-free and RoHS-compliant. Reach, halogen-free status, and conflict-minerals declarations were not present in the supplied verified data. AEC-Q100 is not applicable because the evidence does not identify this part as an automotive-qualified variant.
