DP8390DV Обзор
What is an Ethernet network interface controller? An Ethernet NIC is an interface IC positioned between a computer or embedded controller and an Ethernet physical layer. It handles network-oriented communication tasks and reduces the electrical and protocol burden placed on the host system. In the broader semiconductor hierarchy, the DP8390DV is a communication interface controller, an interface IC, and ultimately a semiconductor used in Ethernet networking equipment and embedded data-processing systems.
The DP8390DV’s primary verified characteristics include a 10 Mbps data rate, a 5 V supply, and approximately 40 mA supply current. Those values place it in the established 10BASE-T-era Ethernet hardware category. Its PLCC package provides a surface-mount PCB footprint with J-leads, while the listed 25.13 mm by 25.13 mm body size supports compact but not especially miniature industrial and legacy-compatible designs.
DP8390D-family devices were designed to ease host interfacing with CSMA/CD local-area networks, including Ethernet Thin networks. The controller therefore belongs in systems where a host bus must communicate through an Ethernet-compatible network interface. Compared with a general-purpose interface IC, its defining value is Ethernet-specific integration: the network function is consolidated into a dedicated controller rather than being implemented entirely with host firmware and discrete logic.
Typical uses include embedded Ethernet controllers, industrial data-acquisition systems, legacy terminal equipment, print servers, network-interface modules, and host adapters designed around the DP8390 family. In these applications, the DP8390DV can serve as the network-facing IC while an external transceiver, magnetic interface, connector, and system controller provide the surrounding physical-layer and host-side implementation.
The principal design consideration is that this is a mature 10 Mbps controller rather than a current multi-gigabit Ethernet PHY or modern system-on-chip interface. Board design must follow the manufacturer pinout and required external components exactly. Signal routing, supply decoupling, thermal exposure, and network magnetics or transceiver selection should be validated against the official DP8390 documentation before layout release.
This page consolidates verified distributor specifications, sourcing information, interface context, and application guidance. It does not invent unprovided pin assignments, timing values, temperature limits, or replacement parts, so unavailable engineering data remains explicitly marked rather than being inferred.

Типичное применение
DP8390DV подходит для 7 применениеs: Legacy 10 Mbps Embedded Ethernet Host, Industrial Data-Acquisition Terminal, Legacy Print-Server Interface, Network Instrumentation Retrofit, Educational Ethernet Controller Trainer, Legacy Network Interface Card Repair, CSMA/CD Network Interface Module.
Legacy 10 Mbps Embedded Ethernet Host
The DP8390DV fits a legacy embedded host that must connect through a 10 Mbps CSMA/CD Ethernet subsystem while retaining an established controller architecture. Its verified 10 Mbps data rate, 5 V supply, and approximately 40 mA supply current align with older embedded control and acquisition equipment. The controller can sit between the host processor and a suitable Ethernet transceiver or physical-layer network interface. Designers should preserve the verified 68-pin J-lead PLCC footprint and obtain the complete host-bus timing and transceiver guidance from official documentation before placing the part in a new board.
Рекомендуется
Industrial Data-Acquisition Terminal
The DP8390DV is applicable to a legacy industrial data-acquisition terminal that links a local controller to a 10 Mbps Ethernet network. The verified 5 V supply and approximately 40 mA supply current are useful baseline power facts, while CSMA/CD and Ethernet Thin support match established LAN installations. The device does not by itself provide the complete physical network path, so the design still needs the approved transceiver, isolation or magnetics arrangement, connector, and protection network. Because the available record identifies commercial grade, industrial temperature requirements must be checked separately.
Рекомендуется
Legacy Print-Server Interface
The DP8390DV can support service and repair work on legacy print servers built around the DP8390 Ethernet controller family. Its verified 10 Mbps rate is sufficient for the network class addressed by the original CSMA/CD architecture, and the 68-pin PLCC package enables reuse of an existing board footprint. The substitution is not automatically safe for unrelated print servers: clock timing, reset behavior, host-bus signals, transceiver selection, and firmware assumptions must match. Procurement and assembly should therefore focus on an exact documented footprint-compatible part rather than merely another Ethernet controller.
Рекомендуется
Network Instrumentation Retrofit
The DP8390DV is relevant when retrofitting an older measurement or laboratory instrument that already uses a DP8390-family interface and a 10 Mbps Ethernet link. In that situation, preserving the 25.13 mm by 25.13 mm, 68-pin J-lead PLCC footprint can reduce board-level rework. The controller must still be paired with the exact compatible physical interface, isolation components, and termination network used by the original design. For newly developed instrumentation, a supported modern controller is generally safer because the provided evidence does not establish the DP8390DV lifecycle state or long-term availability.
Рекомендуется
Educational Ethernet Controller Trainer
The DP8390DV can support an educational Ethernet-controller trainer built around a historical 10 Mbps CSMA/CD design. Its verified 10 Mbps operation, 5 V supply, approximately 40 mA supply current, and documented 68-pin PLCC package make it suitable for demonstrating how a dedicated network interface sits between a host and Ethernet physical layer. The training board should clearly separate controller, transceiver, network coupling, and host-bus sections. Students and instructors should use the official datasheet for clock, timing, pin, and signal definitions because those details are not present in the supplied search evidence.
Рекомендуется
Legacy Network Interface Card Repair
The DP8390DV is directly relevant to repair or inventory replenishment of an interface card that originally used the exact 68-pin J-lead PLCC controller. The verified package dimensions and terminal count help identify the correct board footprint, while the 10 Mbps specification supports CSMA/CD network reconstruction. A replacement should be sourced with the same orderable suffix and inspectable supply chain rather than assumed from generic controller descriptions. Before installation, confirm operating-temperature grade, supply limits, pin continuity, and compatibility with the card’s original transceiver and host circuitry.
Рекомендуется
CSMA/CD Network Interface Module
The DP8390DV can form the controller section of a dedicated CSMA/CD network-interface module for legacy Ethernet equipment. Its verified 10 Mbps rate and Ethernet Thin relevance support this role, while the approximately 40 mA supply current provides a baseline for power-budget planning at the 5 V rail. External circuitry still determines whether the module reaches the connector through a compatible transceiver, isolation elements, and protection. Because no verified drop-in alternate or complete pinout was supplied, the module should be based on original design documentation and checked for timing and signal-integrity requirements.

Заметки по проектированию
Preserve the verified 68-pin J-lead PLCC footprint rather than adapting the design to a generic Ethernet controller. The source identifies a 25.13 mm by 25.13 mm square package and QCCJ package code, but it does not provide land patterns or pin assignments. Before layout release, obtain the official mechanical drawing and compare pad count, lead pitch, pin-one orientation, and keepout dimensions against the selected distributor inventory.
Budget the verified 5 V supply and approximately 40 mA DP8390DV supply current before adding transceiver and support loads. That controller-only arithmetic is about 200 mW at nominal 5 V, calculated as 5 V times 0.040 A. It is an estimate, not a maximum-power specification. Actual rail limits, current transients, startup behavior, and neighboring-circuit demand must be established from official documentation.
Route the host bus, clock, reset, and network-facing signals according to the manufacturer’s original reference design. The supplied evidence does not expose edge rates, bus width, timing margins, or transceiver pin connections, so trace lengths and terminations cannot be responsibly inferred. Preserve continuous ground references, minimize stub branches, and validate the completed layout with the documented clock and interface requirements.
Do not treat any Ethernet controller with similar speed or function as a drop-in replacement for DP8390DV. A safe replacement must match the 68-pin PLCC footprint, pin functions, 5 V electrical environment, timing, and transceiver connection. The supplied cross-reference searches produced no verified pin-compatible alternate. Also check commercial versus extended-temperature requirements because the available Partstack snippet identifies commercial grade only.
Информация о соответствии
The supplied search evidence contains no explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declaration for DP8390DV. The Partstack snippet states commercial temperature grade, which is not an automotive qualification claim.
