LAN9215-MT 概要
An Ethernet controller such as the LAN9215-MT connects an embedded host interface to a physical copper network. Within the hierarchy of integrated circuits, it is an Ethernet interface controller and a networking semiconductor. Its 100 Mbps throughput targets Fast Ethernet networks, while its 16-bit MII provides a parallel connection to a host processor. Integrating the controller and PHY reduces external network-interface component count compared with a discrete MAC-and-PHY design.
Verified features include support for 10 Mbps and 100 Mbps operation, HP Auto-MDIX support, driver compatibility with the preceding LAN9118 family, and footprint, register, and driver compatibility with those devices. The manufacturer datasheet states a 2.97 V to 3.63 V supply range and a maximum clock frequency of 25 MHz. A separate component listing describes a 3.3 V device and an operating range from 0°C to +70°C, consistent with the -MT commercial-temperature ordering option.
The LAN9215-MT is suitable for embedded Ethernet systems that require a CPU-facing parallel interface rather than a serial SPI host interface. Typical uses include industrial controllers, embedded gateways, test equipment, communications modules, and OEM data-acquisition products. Its 16-bit host interface is particularly appropriate for microprocessors and programmable logic devices able to sustain parallel bus transactions at Ethernet timing requirements.
The primary integration consideration is the Ethernet magnetics and analog network path. The manufacturer datasheet notes that supporting HP Auto-MDIX can require different magnetics and passive components plus a minor PCB change. Designers should therefore follow the manufacturer reference schematic and preserve the required layout, power, decoupling, and magnetics implementation rather than treating the controller as a standalone digital component.
This page consolidates verified manufacturer and distributor information, practical integration guidance, application fit, and transparent gaps where complete electrical or pin-level data was not provided. The official LAN9215 product page and datasheet remain the controlling references for registers, timing, electrical limits, and reference design implementation as verified on 2026-10-22.

主な用途
LAN9215-MT の用途: 6 件s: Embedded Industrial Gateway, Embedded Test and Measurement Equipment, Data Acquisition Controller, Networked Embedded Control Panel, Communication Protocol Converter, OEM Network Interface Module.
Embedded Industrial Gateway
The LAN9215-MT suits an embedded gateway whose host processor can operate its 16-bit parallel MII and needs 10/100 Ethernet without a separate MAC. It supports rates up to 100 Mbps, uses a 2.97 V to 3.63 V supply range, and is packaged in a 100-pin 14 x 14 mm TQFP. Place the controller according to the manufacturer reference schematic and validate the Ethernet magnetics, Auto-MDIX implementation, and signal-integrity path. Its compatibility with LAN9118 drivers and registers may simplify migration, although the commercial 0°C to +70°C range and unverified industrial certification must be checked against deployment requirements.
おすすめ
Embedded Test and Measurement Equipment
The LAN9215-MT can provide Fast Ethernet connectivity for test instruments whose CPU or controller supports a 16-bit MII. Its 100 Mbps maximum rate, 25 MHz maximum clock frequency, and integrated 10/100 controller role are appropriate for supervisory control, status reporting, and configuration transfer. The 100-pin TQFP requires careful routing of the parallel host bus and controlled clock and power distribution. Use the official reference design to preserve Ethernet analog layout, magnetics spacing, impedance control, and bypass-capacitor placement, especially in systems where measurement noise could affect analog performance.
おすすめ
Data Acquisition Controller
The LAN9215-MT is a practical network interface for a data-acquisition controller that must transfer digitized results over 10/100 Ethernet. The 16-bit parallel interface offers a direct path to a capable host bus, while 100 Mbps operation provides sufficient bandwidth for many supervisory and control workloads. Performance still depends on host DMA behavior, bus latency, interrupt overhead, and Ethernet frame handling. The manufacturer reference schematic should anchor the MII routing and analog Ethernet section; do not improvise trace lengths or magnetics placement because packet integrity depends on the complete reference network.
おすすめ
Networked Embedded Control Panel
A human-machine interface or embedded control panel can use the LAN9215-MT for wired Ethernet telemetry, configuration updates, and supervisory commands. Its 10/100 support covers common office and industrial Fast Ethernet networks, while the 16-bit MII suits hosts designed for bus-oriented communication. The -MT grade's verified 0°C to +70°C operating range is appropriate for many indoor control panels but not automatically sufficient for extended-temperature use. Validate bootloader behavior, driver licensing, cable protection, Auto-MDIX magnetics, and electromagnetic compatibility before deploying the controller in a finished enclosure.
おすすめ
Communication Protocol Converter
The LAN9215-MT can form the Ethernet side of a protocol converter that bridges a local embedded bus to 10/100 networks. Its 100 Mbps rated throughput and parallel MII support deterministic host transactions when firmware, DMA channels, and interrupt latency are designed carefully. The verified supply range of 2.97 V to 3.63 V supports integration near 3.3 V logic, but level compatibility with the selected processor still must be checked. Follow the official analog reference design and provide solid power distribution to minimize Ethernet errors during simultaneous processor and network activity.
おすすめ
OEM Network Interface Module
The LAN9215-MT is suitable for an OEM module that exposes Fast Ethernet through a 16-bit host bus. Its single-chip controller integration can reduce the number of network ICs compared with separate MAC and PHY implementations, while the standardized TQFP package supports repeatable board assembly. Module designers must still add magnetics, isolation or surge-protection options as required, an accessible RJ45 connector, and compliance-tested board layouts. HP Auto-MDIX can improve cabling flexibility, but the manufacturer notes that its passive and magnetics implementation can require a PCB change.

設計ノート
Use the official LAN9215 reference schematic at https://ww1.microchip.com/downloads/en/DeviceDoc/9215_sch.pdf as the layout baseline. The manufacturer states that HP Auto-MDIX can require changed magnetics, changed passive components, and a minor PCB revision. Preserve the approved Ethernet trace geometry, magnetics placement, controlled-impedance paths, and bypass-capacitor arrangement rather than copying an unrelated PHY circuit by appearance.
Route the 16-bit MII as a controlled, continuous parallel bus on the verified LAN9215 reference design. Maintain consistent impedance and geometry across data and clock paths, minimize stubs, and place termination exactly where the reference design specifies it. The supplied results do not provide complete MII timing or trace-length limits, so those values must be obtained from the official datasheet before PCB signoff.
Design the 3.3 V power rail for the controller and its Ethernet magnetics without excessive trace impedance or shared high-current return disturbance. Place local bypass capacitors at the pins according to the manufacturer schematic and keep switching-converter return currents away from sensitive Ethernet and MII references. Estimated power dissipation cannot be calculated from the supplied data because no verified operating current or efficiency values were provided.
Do not assume that every LAN9118-compatible design automatically implements HP Auto-MDIX with LAN9215. Although the manufacturer states driver, register, and footprint compatibility, its datasheet also calls out passive, magnetics, and minor PCB changes for the Auto-MDIX implementation. Review the exact LAN9118 variant, compare device revision and timing data, and validate Ethernet operation after any substitution.
コンプライアンス情報
The supplied verified results do not state RoHS, REACH, halogen-free, lead-free, or conflict-minerals status. AEC-Q100 is not applicable because the LAN9215-MT is an Ethernet interface controller, not an automotive-qualified component explicitly identified as such.
