DP83810BVUL - PCI Ethernet Controller | Texas Instruments
MPN： DP83810BVUL ✓ 啟用中DP83810BVUL 概覽
An Ethernet controller is an interface IC that connects a host computing system to an Ethernet network. The DP83810BVUL belongs to the broader semiconductor and integrated-circuit hierarchy, where interface devices translate between digital bus data and physical network signaling. Its PCI designation indicates a peripheral component interface-oriented role, while its Ethernet classification identifies the networking function served in systems such as embedded equipment, communications infrastructure, and industrial controllers.
The principal verified features are the DP83810BVUL MPN, the National Semiconductor heritage shown by the marketplace listings, the PCI Ethernet controller category, the 48-LQFP package, and the $7.5575 qty-1 market reference. The verified excerpts do not provide the detailed data rate, transceiver architecture, I/O voltage, clocking requirements, register map, temperature range, or electrical limits. Those values remain unresolved rather than being inferred from similar Ethernet devices.
The part is sourced through several independent marketplace channels. DigiKey lists DP83810BVUL as an Ethernet Controller PCI Interface and indicates that it can ship promptly. LCSC identifies the device as in stock and publishes the $7.5575 starting price. Octopart compares pricing from two distributors, while several additional inventory services list the exact MPN. This broad search footprint supports procurement review, although it does not by itself establish long-term lifecycle commitment.
DP83810BVUL can be evaluated for PCI-based embedded platforms that require Ethernet connectivity, including industrial automation equipment, communications modules, data-acquisition systems, and compact network appliances. The exact interface compatibility, electrical characteristics, reference schematic, magnetic-interface requirements, and software-support expectations should be checked against the manufacturer documentation before a board design is released.
The principal design prerequisite is to avoid assuming that identical package dimensions guarantee a working replacement. A PCI Ethernet controller also requires verified host-bus timing, power sequencing, signal-level compatibility, and appropriate network-transceiver implementation. Input and output capacitance, reference-clock configuration, interrupt behavior, and thermal performance must be taken directly from the relevant documentation and PCB reference design.
This page consolidates the verified distributor identity, current availability, advertised price, package, and procurement links for DP83810BVUL. It also separates confirmed information from unavailable technical parameters, identifies the absence of a verified cross-reference result, and provides transparent guidance for evaluating same-family TI/National Semiconductor variants without presenting unverified specifications as fact.

典型應用
DP83810BVUL 適用於 6 應用s: Industrial Ethernet Control, Embedded Communications Module, Data Acquisition System, Compact Network Appliance, PCI Test and Measurement Platform, Network Security Appliance.
Industrial Ethernet Control
DP83810BVUL can be evaluated as the PCI-facing Ethernet controller in an industrial control system where a host processor needs network connectivity. The verified distributor description establishes a PCI Ethernet controller role, and the exact 48-LQFP package provides a defined surface-mount footprint for controller-based control boards. In this application, the device would sit between the host bus and the Ethernet network interface, allowing operating systems and supervisory software to exchange control, diagnostic, and telemetry data. The engineering benefit is integration of PCI networking into a compact embedded controller without relying on a separate add-in interface card. Before committing to the layout, verify host-bus timing, supply voltage, clock requirements, reference circuitry, interrupt routing, and the exact Ethernet physical interface from the manufacturer documentation. The available $7.5575 qty-1 reference price as of 2026-10-28 also supports initial prototype budgeting, but production suitability still depends on lifecycle and qualification evidence.
推薦
Embedded Communications Module
The DP83810BVUL is relevant to compact communications equipment that exposes Ethernet connectivity through a PCI-capable host processor. Its verified PCI Ethernet controller classification makes it suitable for preliminary design selection in gateways, protocol bridges, and embedded network appliances. The controller can reduce the number of separate host-interface and network-interface functions on a board, while the 48-LQFP package supports dense surface-mount layouts. System-level performance still depends on the undocumented clocking scheme, bus timing, supported Ethernet rate, and physical-layer arrangement, none of which are supplied in the verified excerpts. Engineers should compare those parameters against the intended processor and magnetics or PHY selection before schematic release. Procurement planning can begin using the confirmed in-stock status and $7.5575 starting price as of 2026-10-28, while long-term supply and lifecycle commitments should be requested from the supplier or manufacturer.
推薦
Data Acquisition System
DP83810BVUL can serve as a candidate network interface in a data-acquisition system whose controller uses a PCI-compatible bus and needs to transfer measurement or process data over Ethernet. The verified PCI Ethernet controller description supports that use case at the interface-category level, while current distributor availability can reduce sourcing risk for prototype builds. The device may allow acquisition results, configuration data, and diagnostic records to be shared with a host or remote service without adding a separate network adapter card. Designers must still establish whether the controller supports the required Ethernet speed, media interface, host-bus speed, electrical levels, and clocking arrangement. They should also confirm local drivers, operating-system support, reset requirements, and interrupt behavior. At $7.5575 per unit as of 2026-10-28, the advertised unit price is suitable for early budgeting, but it is not a substitute for a volume quotation or documented lifecycle commitment.
推薦
Compact Network Appliance
DP83810BVUL can be assessed for a compact network appliance in which a host processor provides local control and the controller supplies a PCI Ethernet connection. This arrangement can support configuration interfaces, telemetry links, and remote diagnostics in equipment such as network-control modules and edge devices. The verified marketplace records show that the exact MPN is actively listed by DigiKey and LCSC, with LCSC reporting it in stock and Octopart comparing two distributors. Those facts support initial sourcing, but they do not establish long-term availability. The 48-LQFP footprint is suitable for multilayer PCB assembly, provided that power, clock, host-bus, and network-interface routing follow the verified reference design. Because the supplied excerpts omit Ethernet rate, transceiver configuration, voltage limits, and thermal ratings, the device should remain a design candidate until those parameters and host software requirements are confirmed.
推薦
PCI Test and Measurement Platform
DP83810BVUL can be evaluated for a PCI test or measurement platform that needs wired Ethernet for remote control, data export, laboratory integration, or service diagnostics. Its verified classification as a PCI Ethernet controller fits systems in which a host processor manages test sequencing and must publish results over a network. The 48-LQFP package avoids relying on a legacy plug-in card and can simplify enclosure and backplane integration when the supported host interface and timing requirements are met. Since the supplied sources contain no verified data rate, clock input, voltage range, or transceiver configuration, engineers must consult the exact manufacturer documentation before selecting magnetics, isolation, connectors, or termination networks. The current $7.5575 qty-1 reference price as of 2026-10-28 makes prototype budgeting straightforward, but laboratory and production programs should request traceability, lifecycle status, and a guaranteed supply schedule.
推薦
Network Security Appliance
DP83810BVUL may be considered for a network-security appliance whose embedded control plane needs a PCI Ethernet interface for management traffic, logging, or remote administration. The exact device is documented by marketplace sources as a PCI Ethernet controller and remains listed by several suppliers, which makes it a credible candidate for prototype sourcing. Its 48-LQFP package permits integration beside the host processor and supporting interface circuitry on a multilayer board. Security-focused designs must add system-level controls because the supplied data does not identify cryptographic capabilities, secure-boot features, managed interfaces, supported media, or operating-system drivers. Those characteristics should not be assumed from the controller category. Before hardware freeze, verify the Ethernet PHY or external physical interface, isolation requirements, reset architecture, timing margin, and thermal conditions. The $7.5575 advertised unit price as of 2026-10-28 is a useful initial cost reference, subject to supplier confirmation and volume availability.

主要差異化特點
- Exact-marketplace sourcing for the named orderable MPN (對比DP83810I)
- Verified PCI Ethernet controller classification (對比DP83810IB)
- Direct 48-LQFP package identification (對比DP83810IBS)
設計說明
Do not treat a matching 48-LQFP footprint as proof that any DP83810 suffix is electrically interchangeable. The verified marketplace excerpts do not expose the ordering-code meanings, temperature grades, clock requirements, or device-specific configuration. Before substituting, compare the manufacturer ordering guide, pin table, power specifications, reference-clock section, reset behavior, and Ethernet physical interface. The same-family alternatives listed here are investigation candidates rather than substitutes supported by a verified cross-reference record.
Route the PCI host-bus and Ethernet-facing signals according to the verified reference design rather than a generic LQFP layout. Place decoupling structures at the device power pins with short return paths to the ground plane, and keep the reference-clock network away from Ethernet magnetics and high-current switching nodes. Because the supplied data does not identify voltage rails, clock frequency, or pin assignments, confirm those values before selecting capacitors, pullups, termination networks, or layer-stack rules.
Use the exact power rails, sequencing rules, current limits, and startup behavior listed for DP83810BVUL in the manufacturer documentation. A PCI host system can require deterministic rail ordering, so do not infer capacitor values or regulator headroom from the $7.5575 marketplace reference or from another DP83810 suffix. Validate the assembled rail tolerances, inrush, reset release, and warm restart against the system power budget. These values are data needed because no electrical limits were included in the supplied excerpts.
Plan the Ethernet physical interface and isolation or magnetics section from the approved reference design. Keep high-speed or Ethernet-related copper away from switching nodes and noisy clock sources, and provide the grounding and return-current arrangement required by the actual physical layer. Because neither the integrated PHY arrangement nor supported Ethernet rate is present in the verified records, the external magnetics, connector, and termination choices must remain provisional until the manufacturer documentation is reviewed.
合規資訊
The supplied marketplace excerpts do not provide verified RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations for DP83810BVUL.
