MPN: DP83936AVUL-20 ✓ فعالDP83936AVUL-20 جائزہ
An Ethernet network interface controller is a semiconductor that manages frame processing and the physical connection between a computer or embedded system and a network. The DP83936 belongs to the SONIC-T family, a second-generation Ethernet controller architecture intended for systems requiring parallel data movement, direct memory access, and support for both 16-bit and 32-bit host buses.
The -20 suffix identifies the 20 MHz operating-speed option. According to the manufacturer datasheet, the device supports a 32-bit non-multiplexed address and data bus, full-duplex operation, and a twisted-pair network interface. A supply current of 140 mA is listed for the device, while its 4.75 V to 5.25 V operating supply range is centered on a conventional 5 V system rail.
The parallel host architecture differentiates the DP83936 from compact Ethernet controllers based on serial or reduced-width interfaces. Parallel address and data paths can provide high throughput for systems processing substantial Ethernet traffic, particularly embedded routers, industrial gateways, telecommunications equipment, and legacy computing platforms. The 160-pin package exposes the extensive address, data, control, interrupt, and network-related signals required by this architecture.
Typical applications include embedded Ethernet routers, industrial control gateways, network-interface subsystems, communications equipment, and other 5 V systems using a 16-bit or 32-bit processor bus. The controller can also serve as the Ethernet basis for a platform requiring a dedicated network interface rather than a highly integrated controller with an internal CPU.
PCB design requires careful attention to the 160-pin footprint, 5 V power distribution, high-speed parallel routing, and transmission-line behavior on the host bus. Follow the manufacturer’s pin-description table and layout guidance when assigning every signal, especially reset, interrupt, address, data, and twisted-pair connections.
This product page organizes the controller’s principal electrical, packaging, and interface characteristics, practical application considerations, verified sourcing links, and design guidance. It also distinguishes the 20 MHz device from other SONIC-T clock options so engineers can assess timing compatibility before approving a replacement.

عام استعمالات
DP83936AVUL-20 کے لیے موزوں ہے 6 ایپلیکیشنs: Embedded Ethernet Router, Industrial Control Gateway, Telecommunications Equipment, Network Interface Card, Legacy Computing Platform, Embedded Communications Processor Platform.
Embedded Ethernet Router
The DP83936AVUL-20 fits an embedded router requiring a dedicated parallel-interface Ethernet controller. Its 32-bit non-multiplexed address and data bus can connect directly to a compatible 16-bit or 32-bit system processor, while the full-duplex twisted-pair interface supports network-facing traffic. The 4.75 V to 5.25 V operating range aligns with a conventional 5 V platform. Because this is a large 160-pin controller rather than a highly integrated system-on-chip, the design must also provide suitable Ethernet physical-layer circuitry, bus timing margin, interrupt handling, and 5 V power distribution.
Industrial Control Gateway
The DP83936AVUL-20 can serve as the network engine in an industrial control gateway that bridges a parallel embedded processor to Ethernet. The dedicated SONIC-T architecture separates network-interface work from the host CPU and supports 16-bit and 32-bit host systems. Its 20 MHz operating option and 140 mA listed supply current support planning around a 5 V supply rail. The principal design considerations are deterministic interrupt handling, careful parallel-bus routing, protection for industrial cabling, and ensuring the selected twisted-pair physical-layer implementation meets the required network standard.
Telecommunications Equipment
The DP83936AVUL-20 is appropriate for legacy telecommunications equipment that needs a high-throughput parallel Ethernet interface rather than a compact serial Ethernet controller. The 32-bit non-multiplexed bus can support a processor architecture with wide local data movement, while full-duplex operation suits communication paths that exchange traffic in both directions. The 160-pin square QFP requires a substantial routed footprint, but it provides direct access to the controller’s address, data, control, and network signals. Power integrity and bus timing should be evaluated across the complete 4.75 V to 5.25 V supply range.
Network Interface Card
The DP83936AVUL-20 can form the core of a dedicated network interface card for a 16-bit or 32-bit embedded host. Its SONIC-T architecture provides full-duplex twisted-pair connectivity and a parallel host bus, allowing the host processor to transfer Ethernet frames through direct memory access rather than handling every byte through an 8-bit serial interface. The 28 mm by 28 mm, 160-pin package is most appropriate where board area is available. Signal-integrity review should address long parallel traces, bus termination, clock distribution, reset behavior, and ground-return continuity.
Legacy Computing Platform
The DP83936AVUL-20 is suitable for extending an older computing platform with dedicated Ethernet connectivity. Its parallel interface is designed for systems that do not use a compact packet-oriented Ethernet controller and may require direct access to a wide host bus. The 20 MHz DP83936AVUL-20 option supports a 4.75 V to 5.25 V supply environment and a full-duplex twisted-pair connection. A successful upgrade depends on confirming address decoding, interrupt polarity, bus-cycle timing, DMA-compatible system support, and the mechanical availability of the 160-pin footprint.
Embedded Communications Processor Platform
The DP83936AVUL-20 can complement a communications processor that needs a separate Ethernet path for control traffic or network management. The controller’s 32-bit non-multiplexed address and data bus and support for both 16-bit and 32-bit hosts align with broad embedded processor architectures, while full-duplex twisted-pair operation supports simultaneous bidirectional transfer. Designers should allocate the controller’s interrupts, DMA-related system resources, clocking, and reset circuitry explicitly. Because the parallel interface is extensive, board planning should begin with the complete manufacturer pin table rather than reconstructing signal assignments from memory.

ڈیزائن نوٹس
Use the complete 160-pin manufacturer pin-description table when creating the footprint and netlist. Treat address, data, control, reset, interrupt, clock, power, and twisted-pair connections as one interconnected high-speed digital design. Do not infer a missing pin function from a generic Ethernet-controller symbol, and verify land pattern, pin numbering, exposed connections, and thermal requirements against the package drawing before fabrication.
Route the 32-bit non-multiplexed address and data bus as a controlled parallel interface. Keep address, data, control, and clock traces on consistent layers where practical, eliminate stubs, provide a continuous reference plane, and terminate the interface according to the system timing architecture. Validate setup and hold time, bus timing, clock skew, and signal degradation with the intended processor and the production PCB stack-up.
Plan the 4.75 V to 5.25 V supply network around the controller’s listed 140 mA supply current while allowing for additional interface circuitry and transient demand. Place local high-frequency decoupling at the supply pins, maintain a low-impedance return path, and separate sensitive network or analog sections from switching and high-current routing. Confirm capacitor selection, voltage rating, and loop area against the manufacturer datasheet and the actual system power budget.
