LAN9118-MT Descripción general
An Ethernet controller is an interface integrated circuit that connects an embedded processor or microcontroller to a physical Ethernet network. The LAN9118 family belongs to the broader hierarchy of Ethernet controller -> network interface controller -> interface IC -> semiconductor. Integrating the controller and PHY supports embedded product designs for industrial controls, communications equipment, data acquisition, and networked peripherals, while the parallel host interface gives the host processor direct register and data access.
The verified product information identifies a 32-bit external data bus, a 7-bit address bus, a 25 MHz clock capability, a 3.3 V supply, and a 100-pin TQFP package. The 100-pin package exposes the substantial parallel host interface required by the non-PCI architecture. The LAN9118-MT is therefore most appropriate where an embedded system has enough I/O and board area for a high-pin-count parallel interface rather than a compact serial Ethernet controller.
The part is described as a high-performance single-chip 10/100 non-PCI Ethernet controller. Its combined controller and PHY architecture can reduce the number of external network-interface components compared with a separated MAC and physical-layer design. Ethernet magnetics and the RJ45 connector remain external, and the final signal-integrity and layout implementation must follow the manufacturer hardware guidance. The provided verification also identifies IEEE 802.3 and IEEE 802.3u compliance in a product comparison source.
Typical uses include embedded Ethernet gateways, industrial monitoring equipment, serial-to-Ethernet systems, test instruments, and control systems that require 10/100 connectivity. The parallel interface makes the LAN9118-MT most attractive to designs with a processor bus capable of supporting the required data width and pin count. It is less suitable for highly constrained systems that favor a serial Ethernet interface or a smaller package.
Designers should verify the complete pinout, voltage tolerances, clock requirements, decoupling, reset behavior, magnetics selection, and PCB routing against the manufacturer datasheet before layout release. The verified search results identify the manufacturer LAN9118 product page and multiple datasheet mirrors, but do not provide every electrical timing, pin-level, or lifecycle value needed for a complete production design.

Aplicaciones típicas
LAN9118-MT es adecuado para 6 aplicacións: Embedded Ethernet Gateway, Industrial Monitoring Controller, Data Acquisition System, Networked Test Instrument, Serial-to-Ethernet Gateway, Embedded Communication Appliance.
Embedded Ethernet Gateway
The LAN9118-MT fits an embedded gateway that needs 10/100 Ethernet connectivity and a parallel host interface to a processor with sufficient bus and pin capacity. Its verified 32-bit external data bus and 7-bit address bus make the device suitable for legacy-style embedded processor connections rather than compact serial-only modules. The controller and PHY are integrated in one package, while Ethernet magnetics and the RJ45 connector remain external. Designers should budget PCB area for the 100-pin TQFP and validate the complete bus timing against the selected processor.
Recomendado
Industrial Monitoring Controller
The LAN9118-MT can be used in industrial monitoring equipment that needs a wired 10/100 network path for sensor data, status reporting, or remote configuration. The verified commercial temperature range of 0°C to +70°C makes it a candidate for indoor or controlled-environment equipment, but not an automatic choice for extended industrial temperature ranges. The parallel bus simplifies connection to processors designed around an SRAM-style host interface. Firmware must configure the controller, and the Ethernet magnetics and routing must be designed according to the manufacturer guidance.
Recomendado
Data Acquisition System
The LAN9118-MT is appropriate for a data-acquisition system that must transfer measurements from an embedded processor to a host computer over 10/100 Ethernet. Its combined controller and PHY can reduce interface-component count, while the 100-pin package exposes the parallel bus required for direct processor communication. The design must account for burst traffic, interrupt handling, buffering, and clock requirements. The verified data identifies up to 25 MHz clock capability, but complete timing and throughput details require the manufacturer datasheet.
Recomendado
Networked Test Instrument
The LAN9118-MT can support a networked test instrument that needs deterministic 10/100 Ethernet communications for remote control, firmware loading, or measurement data export. The 32-bit parallel interface is useful with an embedded processor that already exposes a compatible bus, while the integrated PHY reduces the need for a separate Ethernet MAC. The system should include correct reset, clock, decoupling, magnetics, and RJ45 layout. Because the verified data does not provide EMC test results or complete timing limits, qualification remains application-specific.
Recomendado
Serial-to-Ethernet Gateway
The LAN9118-MT can be paired with a microcontroller or processor that converts a local serial protocol into Ethernet connectivity. The verified 32-bit host bus and 7-bit address bus are useful when the gateway processor has a wide parallel memory-style interface and enough available pins. The design must provide a stable 3.3 V supply and a supported clock source, and it must implement the appropriate Ethernet isolation and connector solution. Because the supplied data does not verify protocol offload or operating-system support, software capability must be checked separately.
Recomendado
Embedded Communication Appliance
The LAN9118-MT is suitable for embedded communication appliances that expose a wired 10/100 Ethernet management or data port. Its integrated controller and PHY architecture can simplify the hardware compared with a separated MAC and PHY implementation, while the parallel host interface connects to a processor rather than requiring a serial PHY bus. The 100-pin TQFP footprint requires adequate routing density and careful magnetics placement. Confirm lifecycle status, availability, and software support before using the part in a new long-life design.

Notas de diseño
The verified package is a 100-pin TQFP, so the PCB must provide adequate fanout, via access, and escape routing for the parallel host interface. Place the device, memory interface signals, clock circuitry, and decoupling in the topology recommended by the manufacturer. The high pin count makes assembly and routing errors more likely than in a serial-interface Ethernet controller, so verify land patterns against the official package drawing before fabrication.
The LAN9118-MT is identified as a 3.3 V device, but the supplied data does not include complete voltage tolerances or current limits. Use a regulator and decoupling arrangement that meets the manufacturer requirements, and confirm the exact absolute maximum ratings before connecting external signals. Estimate local power dissipation from the actual supply current and voltage drop only after those values are obtained from the datasheet.
The verified application material calls out Ethernet magnetics and the RJ45 connector as part of the physical network path. Route the controller-to-magnetics links with controlled geometry, minimize discontinuities, and follow the manufacturer reference layout and isolation guidance. Do not treat a generic Ethernet layout as sufficient; magnetics selection, impedance, return paths, and connector mechanics must be reviewed together.
Do not substitute LAN9116-MT, LAN9117-MT, or LAN9118-MD solely because the search results show the same product family or a 100-pin TQFP association. The verified migration note describes different host-interface progressions, and the supplied search data does not prove pin-for-pin compatibility. Check every pin, power rail, clock requirement, reset state, timing parameter, and firmware dependency before approving a replacement.
The verified host interface is 32 bits wide, so bus timing, trace length matching, impedance, and interrupt behavior can influence reliable operation. The supplied data does not include complete timing tables or recommended trace-length limits. Capture or review those values from the official datasheet and validate the assembled board with the intended processor, memory configuration, and operating clock.
Información de cumplimiento
The supplied verified search data does not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations for LAN9118-MT. IEEE 802.3 and IEEE 802.3u are mentioned in a product comparison source, but that does not establish all regulatory compliance claims.
