MC68160AFB - 1/1 Full Ethernet AUI/TP Transceiver | NXP
MPN: MC68160AFB ✗ اختتامِ زندگیMC68160AFB جائزہ
An Ethernet transceiver is an interface IC that converts digital or differential signals into the physical signaling used on an Ethernet medium. The MC68160AFB belongs to the broader network-interface and communications-IC hierarchy: Ethernet transceiver, network interface, interface IC, and semiconductor. Its AUI support provides attachment-unit-interface media access, while its 10BASE-T support provides 10 Mb/s twisted-pair operation. The verified material identifies the device as supporting both connection types through external isolation transformers, rather than integrating a transformer on the same package.
The principal verified features are one transmitter and one receiver, full-Ethernet operation, AUI/TP protocol support, a 4.75 V to 5.25 V supply range, and a 52-pin TQFP/LQFP package. The package is supplied in a tray according to the available component data. The commercial operating-temperature information supplied by one distributor source is 0 degrees C to 70 degrees C. The listed lead-free status says the part contains lead, so it should not be treated as a lead-free or RoHS-compliant modern design choice without additional qualification evidence.
The BiCMOS implementation combines bipolar and CMOS circuit techniques, allowing the interface to provide transmit and receive functions in a mixed-signal package. The verified data does not specify the exact internal transceiver architecture, equalization behavior, isolation requirements, propagation delay, output levels, or maximum cable length. Those parameters must be taken from the manufacturer datasheet before final analog and timing validation. The stated AUI and 10BASE-T support is the key technical feature for determining whether this legacy interface IC is appropriate for a given board.
Typical applications include legacy 10 Mb/s Ethernet adapters, industrial data-collection equipment, embedded control systems, AUI-to-10BASE-T media bridges, and test systems that retain older Ethernet physical-layer infrastructure. In these systems, the MC68160AFB can be used where the system controller already handles the Ethernet MAC or frame protocol and only requires the physical medium interface. It is particularly relevant to equipment that needs selectable AUI or twisted-pair media connections and can accommodate external isolation transformers.
The primary design consideration is system compatibility. The 52-TQFP package, 5 V supply, external isolation-transformer requirement, and legacy Ethernet protocol must all be confirmed before layout. A modern design with integrated 10/100 Ethernet PHY support may be simpler, but replacing this part with a modern PHY is not a pin-compatible substitution and generally requires redesign. For an existing MC68160AFB board, verify the exact pin functions, transformer center-tap requirements, termination network, and signal timing against the manufacturer datasheet before production.
This page consolidates the verified manufacturer and distributor descriptions, exact package and supply information, cross-reference results, and engineering-oriented selection notes. It also distinguishes verified facts from fields that remain unavailable, avoiding unsupported claims about pinout, pricing, detailed timing, or universal replacement compatibility.

Legacy 10 Mb/s Ethernet Adapter
The MC68160AFB fits a legacy Ethernet adapter that requires an IEEE 802.3 AUI connection or a 10BASE-T twisted-pair medium interface. Its verified 1/1 driver-receiver configuration provides one transmit and one receive path, while the 4.75 V to 5.25 V supply range identifies it as a 5 V physical-layer device. The board must include the external isolation transformers specified by the device documentation. Compared with a modern multi-speed Ethernet PHY, its advantage is continuity with an existing AUI/TP architecture rather than higher data rate or integration.

AUI-to-10BASE-T Media Bridge
The MC68160AFB is suitable for a media bridge that must expose both AUI and 10BASE-T connection options. Its verified AUI/TP protocol support is the decisive reason for using this interface rather than a general-purpose serial transceiver, and the external isolation transformers required by the media connections must be included in the design. The 52-TQFP package provides a defined surface-mount implementation for industrial controller boards. The main engineering trade-off is that this is a legacy 10 Mb/s-class interface rather than a modern 10/100 Ethernet PHY.

Embedded Control System Ethernet Port
The MC68160AFB can provide the physical medium interface for an embedded controller that already includes Ethernet frame handling and requires AUI or 10BASE-T connectivity. Using the verified 52-pin package preserves a known controller-board footprint, and the 4.75 V to 5.25 V operating range simplifies integration with legacy 5 V logic. Designers must still budget external isolation transformers and confirm timing against the host interface. For new high-throughput embedded products, a 10/100 PHY is generally more efficient.
تجویز کردہ
Industrial Data Acquisition Equipment
The MC68160AFB can support an industrial data-acquisition enclosure that retains a 10BASE-T network port and operates in a controlled commercial-temperature environment. Its verified 0 degrees C to 70 degrees C grade covers office and many indoor production environments, while the tray package and 52-TQFP outline support conventional surface-mount assembly. Because the interface is obsolete and contains lead according to the supplied listing, lifecycle risk and regulatory fit must be addressed for new production equipment.
تجویز کردہ
Legacy Network Test Equipment
The MC68160AFB is relevant to test equipment designed to exercise or maintain legacy IEEE 802.3 AUI and 10BASE-T connections. Its one-driver, one-receiver arrangement makes it suitable for a controlled interface test path when the tester already handles protocol framing, and its 5 V supply range supports integration with legacy instrumentation. The external isolation transformers are essential on the media side. For broad modern test coverage, adding a separate 10/100-capable PHY is more appropriate than expecting this device to support faster Ethernet.
تجویز کردہ
Obsolete Equipment Repair and Continuation
The MC68160AFB is most defensible in repair, stock recovery, and continuation of equipment designed specifically around its 52-pin AUI/TP interface. The verified commercial-temperature and 5 V specifications help narrow candidate boards, while the external isolation-transformer arrangement identifies the required surrounding circuitry. Because no fully verified drop-in substitute was established, technicians should compare the original schematic and datasheet before installation. Continued use should include an obsolescence review rather than assuming long-term supply assurance.

ڈیزائن نوٹس
Preserve the 52-TQFP footprint, including all 52 gull-wing terminals and the 10 mm by 10 mm body outline. Place the external isolation transformers close to the associated AUI or 10BASE-T connector and route media-side copper away from sensitive digital and clocking circuits. Verify land pattern, exposed-pad treatment if applicable, pin numbering, and component orientation against the manufacturer package drawing before releasing artwork.
Design the MC68160AFB rail for the verified 4.75 V to 5.25 V operating range and keep transient voltage below the absolute maximum rating in the manufacturer datasheet. Provide local high-frequency bypass at the supply pins with the shortest possible ground return. Because no verified quiescent-current or dissipation figures were supplied, calculate power from actual supply current and rail voltage rather than assuming ideal regulator behavior.
Treat the AUI and 10BASE-T media connections as separate external-transformer interfaces and follow the datasheet's required termination, biasing, and isolation-component values. Do not infer those networks from generic Ethernet guidance because this device supports legacy 10BASE-T rather than 100BASE-TX. Validate differential signal quality, return paths, connector mechanics, and cable compatibility with the intended network segment.
Do not substitute a modern Ethernet PHY or a similarly named transceiver without a complete pin and functional comparison. MC68160BFB is a same-family candidate, but the supplied cross-reference record does not establish identical timing, enable, media, or transformer connections. Also do not assume lead-free, RoHS, or extended-temperature compliance from the NXP name; the supplied listing explicitly says the MC68160AFB contains lead.
