LAN9117-MT Обзор
An Ethernet controller is an interface IC that connects an embedded processor or programmable controller to a physical Ethernet network. Within the broader semiconductor hierarchy, the LAN9117-MT belongs to the Ethernet controller family, network interface controllers, interface ICs, and communications semiconductors. By combining controller and physical-layer functions, it can reduce component count while preserving a parallel processor-facing integration path.
The verified product information identifies 10 Mbps and 100 Mbps operation, a 3.3 V supply requirement, a 100-pin TQFP package, and a single-chip architecture. The -MT ordering suffix is associated with a tray package in the available distributor record. Other detailed electrical limits, host-interface timing, register features, media-type behavior, and environmental ratings were not included in the supplied verified excerpts and therefore are not asserted here.
Typical uses include embedded industrial controllers, data-acquisition systems, building-automation equipment, access-control terminals, test instruments, and compact embedded servers. A parallel host interface can suit processors and controllers that do not include an integrated Ethernet MAC, while the integrated PHY simplifies the connection between the digital host bus and the analog magnetics interface.
The primary design consideration is footprint verification: the DigiKey listing describes a 100-TQFP package measuring 14 mm by 14 mm, while another distributor excerpt states 14 mm by 20 mm. Engineers must confirm the exact ordering-code drawing and land pattern against the authoritative manufacturer package documentation before layout release. The -MT suffix and tray packaging must also be confirmed with the current manufacturer datasheet.
This page combines verified manufacturer and distributor descriptions with explicit engineering caveats. It does not infer unavailable electrical, timing, thermal, or compliance values, and it separates confirmed product identity from details that still require datasheet-level verification.

Типичное применение
LAN9117-MT подходит для 7 применениеs: Embedded Industrial Controller, Building Automation Gateway, Data Acquisition System, Access-Control Terminal, Compact Embedded Server, Test and Measurement Instrument, Networked Sensor Hub.
Embedded Industrial Controller
The LAN9117-MT fits an embedded industrial controller that needs a dedicated 10/100 Ethernet connection without an Ethernet MAC and PHY integrated into the host processor. Its verified single-chip architecture combines a 10/100 controller with a Base-T/TX PHY, while the parallel interface provides a direct path to compatible digital logic. This integration can reduce board partitioning, but the design must still include the required magnetic network interface, protection, connector, and reference-layout implementation. Confirm processor bus voltage, timing, clocking, driver support, and the exact 100-pin package before schematic release.
Рекомендуется
Building Automation Gateway
LAN9117-MT is suitable as a building-automation communication component when the gateway requires 10 Mbps or 100 Mbps Ethernet and the host cannot provide that network interface itself. The single-chip controller and integrated Base-T/TX PHY help isolate network termination and protocol processing from the application processor. A robust implementation must follow the manufacturer reference network for magnetics, termination, isolation decisions, controlled-impedance routing, and protection. Confirm EMC, temperature, lifecycle, and exact package data because the supplied snippets do not provide those qualifications.
Рекомендуется
Data Acquisition System
A data-acquisition enclosure can use the LAN9117-MT to add wired Ethernet transport to sensors, counters, or laboratory control logic. The verified 10/100 Mbps support and integrated PHY are appropriate for supervisory data exchange, configuration, and status reporting rather than time-critical bulk streaming guarantees. Host processing and memory bandwidth must sustain the selected packet rate, while the Ethernet path must preserve the manufacturer-recommended magnetics and controlled-impedance layout. Verify host-bus timing, thermal conditions, isolation strategy, and driver maturity before deployment.
Рекомендуется
Access-Control Terminal
The LAN9117-MT can support an access-control terminal that exchanges authorization, audit, and configuration traffic over a 10/100 Ethernet link. The dedicated controller is useful when the terminal's main processor lacks suitable Ethernet hardware, while the integrated PHY simplifies the host-to-network boundary. Product designers still need to address secure boot, authenticated communication, cable faults, surge protection, and loss-of-network behavior. The supplied data does not verify security features or environmental ratings, so those requirements must be handled separately at the system level.
Рекомендуется
Compact Embedded Server
LAN9117-MT can provide the wired-network endpoint for a compact embedded server that exposes configuration, telemetry, or firmware services over 10/100 Ethernet. The parallel interface makes the controller relevant to processor platforms with a suitable external bus, but software-driver maturity and sustained packet throughput must be evaluated rather than inferred from the 100 Mbps headline rate. Use the manufacturer reference design to implement magnetics, termination, isolation options, and layout. Verify package dimensions and pinout because the supplied distributor excerpts conflict.
Рекомендуется
Test and Measurement Instrument
In a test or measurement instrument, the LAN9117-MT can add remote-control and data-transfer connectivity when the instrument controller lacks a suitable Ethernet controller. The integrated 10/100 Base-T/TX PHY reduces the number of active network components, but reliable instrument operation still depends on deterministic firmware, isolated communication, calibrated timing, and careful separation between sensitive analog or RF sections and Ethernet return currents. The supplied excerpts do not verify noise, isolation, timing, or temperature specifications, so laboratory validation and authoritative datasheet review are essential.
Рекомендуется
Networked Sensor Hub
The LAN9117-MT can serve as the Ethernet communications section of a networked sensor hub that aggregates measurements from local sensors and forwards them to a supervisory network. Its verified 10/100 Mbps support provides sufficient nominal bandwidth for many control, status, and periodic telemetry workloads. The hub should use the recommended Ethernet magnetics, protection, and controlled-impedance routing, while separating high-current actuator returns from sensitive sensor circuitry. Host driver performance, package fit, thermal conditions, and lifecycle availability require confirmation before volume deployment.

Заметки по проектированию
Resolve the package conflict before layout release. The DigiKey result identifies a 100-TQFP, 14 mm by 14 mm package, while the Veswin excerpt reports 14 mm by 20 mm. Download the current Microchip ordering information and package drawing for LAN9117-MT, then use that drawing for land patterns, courtyard clearance, solder mask, pin numbering, and assembly documentation. Do not scale one package interpretation to match the other.
Route the Ethernet physical network exactly from the approved reference design, including controller-to-magnetics geometry, termination placement, return paths, and differential-pair symmetry where applicable. Keep switching nodes and high-current return paths away from sensitive analog or RF areas. Because the supplied data does not include the complete reference layout or stack-up requirements, use current Microchip design guidance rather than estimating dimensions from general Ethernet conventions.
Do not treat LAN9117, LAN9117-MT, LAN9117-MD, or LAN9118-MT as automatically interchangeable merely because the descriptions refer to 10/100 Ethernet controllers. Verify the order suffix, package dimensions, all pin assignments, supply tolerances, clock requirements, interface timing, absolute maximum ratings, transceiver behavior, and register compatibility. The supplied search results do not establish true pin-to-pin interchangeability for any candidate.
The verified distributor excerpt specifies 3.3 V operation, but it does not provide current consumption, rail tolerance, sequencing, or decoupling requirements. Before schematic capture, obtain the current manufacturer datasheet and identify every supply pin and its allowable range. Follow the specified bypass-capacitor network and place each required capacitor close to its assigned power pin, with low-impedance plane connections and a return path that avoids Ethernet transient currents.
The host-side parallel interface can be sensitive to clock skew, bus loading, signal reflection, and incorrect trace topology. The supplied excerpts do not state bus width, logic levels, clock frequency, or timing margins, so no impedance or termination value can be responsibly prescribed. Derive interface constraints from the current datasheet, then validate them through stack-up-controlled routing and signal-integrity simulation or measurement.
Информация о соответствии
The supplied excerpts contain no RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification statements. AEC-Q100 is marked not_applicable because no automotive use is established; this is not an automotive qualification decision.
