DP83902AVLJ - 5V Serial Network Controller | Texas Instruments
N.º da peça: DP83902AVLJ ✗ Fim de vidaDP83902AVLJ Visão geral
A serial network interface controller is an integrated circuit that manages the communication path between a computer or embedded system and a network medium. In the product hierarchy, this controller belongs to interface ICs and ultimately to the broader semiconductor category. The DP83902AVLJ was designed around twisted-pair network connectivity, where a physical-layer transceiver is commonly paired with a controller. The controller handles network framing and data exchange, while the external transceiver performs signal encoding, reception, and electrical isolation from the copper medium.
The DP83902AVLJ uses a 4.75 V minimum and 5.25 V maximum supply voltage, giving system designers a nominal 5 V operating rail. The verified distributor listing reports a supply current of 140 mA. Its 100-pin QFP package provides a substantial number of external connections, which is typical for legacy Ethernet controllers that require parallel host data paths, address and control signals, clocking, interrupt signaling, and twisted-pair transceiver interfaces. Package dimensions, pin names, operating-temperature limits, Ethernet data rate, transceiver interface details, and electrical timing limits are not included in the supplied verification data.
The DP83902AVLJ is most relevant to legacy networking equipment, industrial control systems, embedded controllers, and industrial Ethernet designs that already use this controller and its associated application circuitry. It should not be assumed interchangeable with a modern Ethernet controller merely because both perform networking functions. The verified cross-reference material specifically states that the STMicroelectronics SERC816/TR is not a direct drop-in replacement because its pinout, internal biasing, and MII timing characteristics differ. A PCB replacement therefore requires a detailed electrical, timing, and pin-level review rather than a simple component substitution.
This page consolidates the verified distributor specifications, lifecycle information, sourcing details, and replacement constraints for DP83902AVLJ. Pricing is presented as unavailable because the verified sources provide quote or request-for-quotation terms rather than numeric unit prices. The pin table records all 100 package terminals but marks individual terminal names as unavailable rather than guessing pin functions. Engineers should obtain the manufacturer datasheet and original design reference before layout changes, firmware updates, or obsolescence redesigns.

Aplicações típicas
DP83902AVLJ é adequado para 6 aplicaçãos: Legacy Industrial Ethernet Control, Embedded Twisted-Pair Networking, Legacy Network Interface Card Repair, Server and Switch Spare Parts, Network Test Equipment, Obsolescence Continuity Engineering.
Legacy Industrial Ethernet Control
The DP83902AVLJ is appropriate for maintaining a legacy industrial Ethernet controller board whose original design already uses its 100-terminal QFP device, 5 V supply, and associated driver software. Its verified 4.75 V to 5.25 V operating range suits a regulated 5 V rail, while the reported 140 mA supply current identifies the load that the system power design must accommodate. Because the part is obsolete, the strongest use case is repair or continuation of proven equipment rather than new platform development. Engineers should preserve the original schematic, board revisions, transceiver selection, and firmware configuration when sourcing a replacement or redesigning around a supported controller.
Recomendado
Embedded Twisted-Pair Networking
The DP83902AVLJ can support an existing embedded system that uses a dedicated serial network interface controller for twisted-pair communication. Its serial interface and commercial temperature grade match the role of a general-purpose networking controller, while the 4.75 V to 5.25 V supply range requires a stable nominal 5 V source in the host design. The verified 140 mA supply-current figure is important when budgeting the controller rail. Designers should not reuse a modern Ethernet PHY by assumption; the controller-to-transceiver signal definitions, timing, isolation, magnetics, and software interface must be confirmed against the original system documentation.
Recomendado
Legacy Network Interface Card Repair
The DP83902AVLJ is relevant to repair and continuation sourcing for legacy network interface cards built around the DP83902A family. The verified catalog data identifies the package as a 100-BFQFP supplied in a tray, allowing engineers to check board compatibility before procurement. Its obsolete lifecycle status means that inventory may be limited, and quotation sellers should be asked about factory-sealed status, traceability, date code, and storage history. Before installation, verify that the replacement has the correct suffix, package terminal arrangement, supply requirements, and transceiver compatibility rather than relying only on the base device description.
Recomendado
Server and Switch Spare Parts
A DP83902AVLJ may be used in selected spare-part workflows for older server, switch, or network-adapter hardware that originally incorporated the controller. The 100-QFP package and obsolete status mean that procurement teams need exact board-level confirmation before treating the device as a universal spare. The verified 5 V supply range and 140 mA current provide initial electrical screening, but they do not establish temperature grade limits or data-rate suitability. Maintain the original manufacturer part number in approved vendor lists, require traceability where required, and test every replacement board at the interfaces affected by the network controller.
Recomendado
Network Test Equipment
The DP83902AVLJ may appear in legacy network test equipment or protocol analyzers that were designed around a dedicated twisted-pair serial controller. Such equipment often depends on exact timing and software behavior, making the original part preferable when repairing an unchanged platform. Its reported 140 mA supply current and 5 V operating range help identify the correct power section during fault analysis. For new test equipment, however, engineers should evaluate currently supported controllers with documented driver APIs and current sourcing. Any migration requires comparison of media access behavior, frame handling, bus timing, interrupt latency, and host-platform compatibility.
Recomendado
Obsolescence Continuity Engineering
The DP83902AVLJ is directly relevant to obsolescence management because it is verified as obsolete while still appearing at distributors with reported inventory and quotation-based fulfillment. Continuity engineers can use the 100-BFQFP package, 4.75 V to 5.25 V supply range, and 140 mA supply current to identify affected assemblies. The absence of verified drop-in alternatives means a resilience plan may require a last-time-buy decision, retained stock, board respin, or software-supported controller migration. The SERC816/TR may inform functional redesign, but its verified pinout, biasing, and MII timing differences prevent treating it as a no-change substitution.

Principais diferenciais
- Exact-fit continuation for the legacy DP83902A controller platform (vs SERC816/TR)
- Documented 5 V operating range (vs SERC816/TR)
- Established tray-packaged 100-terminal legacy form factor (vs SERC816/TR)
Notas de projeto
Do not treat a functionally similar Ethernet controller as a drop-in substitute. The verified SERC816/TR comparison identifies differences in pinout, internal biasing, and MII timing characteristics. A replacement must be checked against the complete DP83902A pin list, power requirements, transceiver signals, clocking, reset behavior, interrupt handling, and host-side software before any board or firmware change is approved.
Design or service the controller rail for a nominal 5 V supply within the verified 4.75 V to 5.25 V range. The reported 140 mA supply current is the verified baseline, but it should not be treated as the maximum transient demand without the manufacturer timing and load data. Decoupling values, allowable ripple, startup sequencing, and power-consumption limits require confirmation from the original DP83902A datasheet and schematic.
For continued production of an unchanged board, source the exact 100-BFQFP package and verify pin-one orientation against the board footprint. The verified catalog data identifies a 14 mm by 20 mm 100-QFP with gull-wing terminals, but the supplied excerpt does not include a land pattern or complete dimensions. Inspect the original component, assembly documentation, and manufacturer drawing before approving solder paste, stencil, or placement changes.
The controller is specified as commercial grade, and its verified catalog listing supplies a 140 mA operating current. These facts do not establish permissible ambient temperature, junction temperature, or package dissipation. For long-term continuation sourcing, document the original thermal conditions and request the manufacturer datasheet or qualified engineering data. Avoid adding heat-sink assumptions based solely on the 100-QFP package because the actual dissipation and board thermal path are not provided.
Legacy twisted-pair Ethernet interfaces often combine a controller, transceiver, isolation barrier, magnetics, and a host bus. During repair, preserve original component placement, high-speed trace topology, grounding, and isolation clearances unless a complete reference design supports changes. The verified material does not identify signal names or timing values, so the original layout must remain the authority when maintaining an existing DP83902AVLJ design.
Informações de conformidade
The supplied verified data identifies the product as commercial grade but does not extract RoHS, REACH, lead-free, halogen-free, or conflict-minerals declarations. AEC-Q100 is marked not_applicable because the device is a commercial-grade network interface controller rather than an identified automotive-qualified part.
