KSZ8041NLI-TR - 10/100 Ethernet PHY | Microchip
MPN: KSZ8041NLI-TR ✓ NakahandaKSZ8041NLI-TR Ulas
An Ethernet PHY, or physical-layer transceiver, converts digital frame data into electrical signaling for a 10/100 Ethernet link and converts received link signals back into data for the host controller. The KSZ8041 sits between an Ethernet MAC or microcontroller with MII/RMII support and the transformer-coupled network interface, providing the physical signaling layer required by IEEE 802.3 Ethernet designs.
Key verified features include 10/100Base-TX operation, full MII and RMII interface support, single-supply operation, and a 32-QFN package measuring 5x5 mm. The manufacturer describes a mixed-signal design intended to extend signaling distance while reducing power consumption. The part is identified by the -TR ordering suffix and is listed in tape-and-reel commercial distribution channels.
The interface architecture makes the KSZ8041 suitable for embedded Ethernet designs, including industrial controllers, embedded processors, set-top boxes, access equipment, and other systems that require a 10/100 Ethernet physical layer. MII support suits designs requiring separate transmit and receive data paths, while RMII can reduce the number of digital interface signals when supported by the host controller.
When placing the device, follow the manufacturer package and land-pattern requirements, provide the specified decoupling and Ethernet magnetics interface components, and route high-speed or high-current network-side connections according to the applicable reference design. The exact pin names, pin functions, electrical limits, and recommended external-component values require confirmation from the official manufacturer datasheet before layout release.
This page consolidates verified manufacturer and distributor information for KSZ8041NLI-TR and distinguishes confirmed product facts from parameters that were not included in the supplied search data. It is intended to support component identification, sourcing, and preliminary engineering review rather than replace the complete Microchip datasheet.

Tipikal na mga Gamit
KSZ8041NLI-TR ay nararapat para sa 6 aplikasyons: Industrial Embedded Ethernet, MII-Based Network Controller, RMII Network Interface, Access Equipment, Set-Top and Consumer Network Products, Networked Measurement and Control.
Industrial Embedded Ethernet
KSZ8041NLI-TR fits industrial embedded controllers that need a dedicated 10/100 Ethernet physical layer beside a host processor or microcontroller. Its verified 10Base-T/100Base-TX support and MII/RMII interfaces provide a clear separation between Ethernet framing in the host and physical signaling at the network interface. In a typical design, the host connects through MII or RMII while the PHY drives and receives the transformer-coupled copper link. The exact temperature range, electrical limits, ESD rating, and magnetics requirements should be confirmed from the official datasheet before release.
Inirekomenda
MII-Based Network Controller
For designs using a host controller with a parallel MII interface, KSZ8041NLI-TR provides a conventional 10/100 Ethernet PHY endpoint while the host handles higher-level frame processing. MII offers separate transmit and receive paths, which can help systems maintain clearer signal ownership than a shared-interface implementation. The PHY is used with the appropriate Ethernet magnetics and network-side protection arrangement. Designers should verify clocking, reset sequencing, MDIO/MDC behavior, and all pin assignments against the complete Microchip documentation rather than relying only on the distributor package description.
Inirekomenda
RMII Network Interface
KSZ8041NLI-TR is appropriate for compact embedded systems whose host controller exposes RMII rather than a full MII interface. RMII reduces the number of parallel network-control signals and can simplify board routing when the host clocking and I/O arrangement are designed carefully. The PHY still requires a compatible reference clock, reset behavior, and digital voltage interface. Before layout, compare the RMII timing and pin mapping in the Microchip datasheet with the host MCU or processor datasheet, then validate signal integrity under the intended 100 Mbps operating mode.
Inirekomenda
Access Equipment
The KSZ8041NLI-TR can support 10/100 Ethernet connectivity in access and edge equipment where a host processor handles application traffic and the PHY handles the physical layer. The single-supply 3.3 V architecture is consistent with many embedded 3.3 V systems, while MII/RMII flexibility permits integration with different controller families. A practical implementation should include the manufacturer-recommended decoupling, isolated or non-isolated Ethernet magnetics decision, RJ45 integration, and proper return-path layout. The supplied data does not include a specific reference design, so component values must be taken from current Microchip documentation.
Inirekomenda
Set-Top and Consumer Network Products
KSZ8041NLI-TR is suitable for consumer or set-top products requiring wired 10/100 Ethernet in place of a wireless-only network path. A host SoC can use MII or RMII for frame transfer, while the KSZ8041 handles 10Base-T/100Base-TX physical signaling. The interface can simplify adding wired connectivity to an embedded platform that already has Ethernet MAC logic but lacks a physical layer. Product teams should confirm regulatory, isolation, ESD, and cable-side implementation requirements locally; the supplied verified data does not establish those application-specific qualifications.
Inirekomenda
Networked Measurement and Control
KSZ8041NLI-TR can provide a wired Ethernet path in measurement, test, and industrial-control systems that need deterministic connectivity to a host controller. The 100 Mbps capability is suitable for supervisory data, configuration traffic, and ordinary control-plane communication rather than a high-speed storage path. The PHY’s MII/RMII flexibility allows it to sit beside processors with different host-interface resources. For reliable deployment, validate timing margins, grounding and isolation strategy, cable-side protection, and thermal performance in the final enclosure; these requirements are not quantified in the supplied verified data.

- Single 3.3 V supply architecture (kumpara saKSZ8041NL)
Talaan ng Disenyo
Treat the Ethernet PHY as a mixed-signal design and keep the host digital interface, PHY supply return, and transformer-side network return paths disciplined. Place the required input and output decoupling close to the device pins, follow the manufacturer’s recommended land pattern, and preserve a continuous ground reference. Do not infer exposed-pad or QFN pin locations from the generic package drawing; verify the actual KSZ8041 package drawing before release.
For MII or RMII operation, verify reference-clock source, clock duty cycle, I/O voltage compatibility, reset sequencing, and edge-rate margins against the host controller. RMII can reduce pin count but makes clock and signal timing coordination more important. At 100 Mbps, use the manufacturer’s recommended termination, controlled impedance routing, and test points; the supplied data does not specify trace impedances or timing values.
Do not substitute KSZ8041NL, KSZ8041NL-TR, KSZ8041NLI, or KSZ8081RNACA solely because the family name or package family appears similar. Confirm pin names, MII/RMII mapping, supply limits, temperature grade, reset behavior, MDIO/MDC function, and Ethernet magnetics requirements from the current manufacturer datasheets. A package match alone is insufficient proof of drop-in compatibility.
