DP83902AV/NOPB - 10BASE-T Ethernet Controller
MPN: DP83902AV/NOPB ✗ Akhir HidupDP83902AV/NOPB Ringkasan
An Ethernet controller is an interface IC that connects a host or embedded system to a physical-layer network. The DP83902AV/NOPB belongs to the ST-NIC family and is intended for IEEE 802.3 10BASE-T networking. Unlike a switching Ethernet transceiver designed for modern 100 Mb/s or multi-gigabit links, this device targets legacy 10BASE-T equipment where established system architecture and installed cabling remain important.
The device operates from a conventional 5 V supply, accepting voltages from 4.75 V through 5.25 V. Its specified supply current is 140 mA. The package is an 84-pin J-lead PLCC with a 29.31 mm by 29.31 mm body, and the documented shipping format is a tube. The suffix NOPB identifies a lead-free ordering configuration associated with this manufacturer’s RoHS-compliant product documentation.
DP83902AV/NOPB combines the logical Ethernet controller and 10BASE-T physical interface in one integrated circuit. This integration reduces the number of network-interface components required in a conventional 10BASE-T design. The serial interface is consistent with the ST-NIC architecture used in IEEE 802.3 systems, allowing the controller to serve as the principal interface between host-side logic and the twisted-pair physical layer.
Typical uses include legacy network interface cards, embedded industrial Ethernet equipment, test systems, and industrial-control products whose original architecture was designed around the IEEE 802.3 10BASE-T standard. The device may also appear in equipment maintenance and obsolescence programs where preserving the original 84-pin PLCC footprint is preferable to redesigning the network interface.
A replacement decision should prioritize the complete pinout, electrical characteristics, clocking arrangement, media-access behavior, and software-driver expectations. Do not assume that another Ethernet controller is interchangeable solely because it also supports 10BASE-T. A qualified replacement must preserve the 84-pin PLCC land pattern and the original system-level timing and register requirements.
This product page combines the controller identity, operating limits, package information, verified drop-in information, comparison parameters, and engineering selection guidance. That practical context helps engineers distinguish a genuine footprint-compatible replacement from a merely similar Ethernet interface before committing to a redesign.

Aplikasi Umum
DP83902AV/NOPB cocok untuk 6 aplikasis: Legacy Network Interface Cards, Industrial Control Terminals, Test and Measurement Instruments, Embedded Data Acquisition, Legacy Network Printers, Obsolete Equipment Maintenance.
Legacy Network Interface Cards
The DP83902AV/NOPB fits legacy PCI, ISA, or similarly engineered network interface cards that require an IEEE 802.3 10BASE-T controller rather than a modern multi-speed Ethernet PHY. Its 84-pin PLCC package preserves the footprint used by the original ST-NIC design, while the 4.75 V to 5.25 V supply supports conventional 5 V logic. The documented 140 mA supply current makes it appropriate for systems designed around this controller generation. During repair or conversion work, use the manufacturer pin and timing tables to verify connector, isolation, and clock connections before substituting the NOPB ordering form.

Industrial Control Terminals
The DP83902AV/NOPB can support an industrial terminal or control cabinet product that retains a 10BASE-T network interface. The Texas Instruments DP83902AV datasheet identifies an IEEE 802.3 10BASE-T PHY with a serial interface and a 4.75 V to 5.25 V supply range. These characteristics align with older supervisory, logging, or factory-floor equipment built around 5 V ST-NIC logic. Before deployment, confirm the ordered temperature grade, isolation requirements, and network magnetics because 10BASE-T compliance alone does not establish suitability for the complete industrial environment.
Direkomendasikan
Test and Measurement Instruments
The DP83902AV/NOPB is appropriate for test and measurement instruments that communicate with a legacy 10 Mb/s Ethernet management port. Its 84-pin PLCC package can be used when an instrument’s original network controller has become unavailable, while the specified 140 mA supply current provides a defined design point for the original 5 V system. A replacement should be validated for crystal frequency, reset behavior, media-access timing, and driver compatibility. Modern laboratory equipment generally uses faster Ethernet, but preserving the ST-NIC path can minimize disruption to an otherwise working instrument.

Embedded Data Acquisition
The DP83902AV/NOPB can serve in embedded data-acquisition equipment designed around a 10BASE-T host interface. The IEEE 802.3 10BASE-T support and serial controller architecture are useful where a device must communicate through an established 5 V Ethernet interface rather than a newly selected PHY. The 84-pin PLCC package offers a defined repair path for legacy acquisition equipment, subject to full pinout and timing verification. Designers should also evaluate cable length, isolation, grounding, and the availability of network transformers because controller compliance does not remove those system-level constraints.
Direkomendasikan
Legacy Network Printers
The DP83902AV/NOPB fits repair programs for network printers and other office peripherals that originally used an IEEE 802.3 10BASE-T interface. The device’s 84-pin PLCC footprint can allow an existing controller board to be serviced without changing its principal land pattern, while the 4.75 V to 5.25 V operating range matches typical legacy logic rails. Qualification should cover the device’s supply-current demand, thermal environment, connector magnetics, and firmware assumptions. A faster Ethernet controller may simplify future platform work, but it would generally require a board-level redesign.

Obsolete Equipment Maintenance
The DP83902AV/NOPB is particularly relevant to maintenance and obsolescence programs for equipment built with the original ST-NIC architecture. Its 84-pin J-lead PLCC package and documented 4.75 V to 5.25 V supply range support targeted board repair, while the 140 mA specification assists power-budget verification. The correct engineering process is to compare the manufacturer pinout, clock requirements, network interface, and system reset behavior with the failed device. For mixed fleets, maintaining the legacy interface can be more practical than replacing the complete controller subsystem while still producing the same external network behavior.

Catatan Desain
Do not treat any 10BASE-T controller as interchangeable with the DP83902AV/NOPB. The replacement must preserve the complete 84-pin PLCC signal map, the 4.75 V to 5.25 V supply range, clocking, reset, interrupt, and media-access timing. Confirm the manufacturer pin-description table and application circuit against the installed board before approval. In particular, verify that the candidate suffix has the required temperature grade and packaging configuration.
Use 140 mA as the documented DP83902AV supply-current design point and reserve additional margin for associated logic and network-interface circuitry. The permitted supply range is 4.75 V to 5.25 V, so a rail outside those limits is not acceptable without separate engineering review. Check bypass-capacitor placement and supply sequencing on the original board rather than relying only on the controller’s operating range. For Estimated: at 5.25 V and 140 mA, the controller’s maximum-state supply power is 0.735 W before considering the 5 V input tolerance.
Preserve the original 84-pin PLCC footprint, pad geometry, pin-1 orientation, and short copper paths for clock and high-speed control signals when making a board-level repair. Route the Ethernet differential connection and magnetics interface according to the manufacturer application circuit, and retain suitable isolation boundaries where required. Because the package is a legacy J-lead PLCC, inspect solder joints and thermal stress during maintenance; electrical substitution alone does not correct compromised board-level reliability.
