KSZ8441HLI - IEEE 1588v2 Ethernet Controller | Microchip
N.º de pieza: KSZ8441HLI ✓ ActivoKSZ8441HLI Descripción general
An Ethernet controller is an interface integrated circuit that connects a host processor or embedded system to an Ethernet physical network. The KSZ8441 combines a MAC, a PHY, and IEEE 1588v2 synchronization in one device. This integration reduces the number of external network components while supporting industrial Ethernet endpoints where protocol timing and network availability are more important than maximum data throughput.
The verified product information identifies the KSZ8441 as a 10/100 Ethernet controller with IEEE 1588v2 support and an internal MAC and PHY. Its 64-LQFP package provides a substantial number of connections for power, ground, Ethernet media, clocking, host-interface, and control signals. The specific protocol, electrical, timing, and host-interface details not present in the supplied search records are marked as DATA_NEEDED rather than inferred from other Ethernet devices.
Typical uses include industrial Ethernet endpoint controllers, synchronized test and measurement equipment, factory automation nodes, embedded control systems, and communication equipment that must exchange data while maintaining time alignment across a network. IEEE 1588v2 support is particularly relevant when distributed devices need deterministic event timing, synchronized acquisition, or coordinated machine operation.
Designers should verify the complete pin assignment, host-interface mode, clock requirements, supply voltages, magnetic-interface components, and timing margins in the manufacturer datasheet before layout release. The 64-pin land pattern must be treated as a function-specific footprint rather than a generic LQFP because unused pins, reserved pins, and power distribution must be implemented exactly as specified by Microchip Technology.
This page combines verified manufacturer and distributor information, technical application guidance, comparison placeholders, and acquisition details. It also distinguishes exact drop-in alternatives from functionally similar Ethernet PHYs that use different packages and therefore cannot replace the KSZ8441HLI without PCB redesign.

Aplicaciones típicas
KSZ8441HLI es adecuado para 6 aplicacións: Industrial Ethernet Endpoint, Precision Test and Measurement, Synchronized Factory Automation, Embedded Control Gateway, Networked Monitoring Equipment, Communication Equipment.
Industrial Ethernet Endpoint
The KSZ8441HLI fits industrial Ethernet endpoints that require both 10/100 Mbps communication and IEEE 1588v2 synchronization. Its internal MAC and PHY consolidate the protocol and physical-layer functions needed at the edge of a factory network, reducing the number of discrete network devices connected to the host. The controller can participate in systems where machines or controllers must exchange process data on a common network while maintaining time alignment across distributed equipment. Before schematic release, engineers should verify the supported host interface, reference-clock arrangement, Ethernet magnetics, reset requirements, and exact 64-LQFP pin assignments in the manufacturer documentation.
Recomendado
Precision Test and Measurement
The KSZ8441HLI is appropriate for synchronized test and measurement systems that transfer data over 10/100 Ethernet and need IEEE 1588v2-based timing. Combining the MAC and PHY in one controller supports equipment designs that require network communication without relying on a separate host-interface architecture. Synchronization capability can help align measurements, trigger events, or timestamps across distributed instruments. The principal design trade-off is that 100 Mbps is below modern multi-gigabit Ethernet rates, so applications with sustained high-volume transfer should confirm bandwidth requirements. Clock quality, timestamp accuracy, latency, media components, and host timing must be evaluated against the datasheet.
Recomendado
Synchronized Factory Automation
The KSZ8441HLI can support synchronized factory-automation nodes that exchange control data over 10/100 Ethernet and benefit from IEEE 1588v2 timing services. Integrating the MAC and PHY creates a compact network endpoint for equipment controllers, I/O systems, and production machines. Timing synchronization may be valuable when independent axes, sensors, or robotic stations must coordinate events within a common industrial network. A practical implementation must account for network topology, switch support for precision time protocol, cable characteristics, isolation requirements, and the controller's specified clock source. The 64-LQFP footprint also requires careful escape routing and adequate thermal copper around the device.
Recomendado
Embedded Control Gateway
The KSZ8441HLI is suitable for an embedded gateway that connects a microcontroller or processor to a 10/100 Ethernet industrial network while also supporting IEEE 1588v2 synchronization. Its integrated MAC and PHY simplify the architecture compared with a design that requires separate host-interface and physical-layer components. This can be useful in data concentrators, machine controllers, remote monitoring units, and communication gateways. Designers should confirm that the host processor can support the selected device interface and that the required protocol software and Ethernet driver are available. Power sequencing, magnetics, reference clocks, isolation, PCB routing, and thermal performance remain design-specific responsibilities.
Recomendado
Networked Monitoring Equipment
The KSZ8441HLI supports networked monitoring equipment that needs 10/100 Ethernet connectivity and IEEE 1588v2 timing across distributed sensors or instruments. A monitoring endpoint can use the integrated MAC and PHY for local communication while maintaining a common time reference for recorded events. This is relevant to environmental, process, and condition-monitoring systems where event alignment improves data interpretation. The design must validate timestamp resolution, clock-drift behavior, packet handling, host-driver behavior, and network infrastructure support for the selected synchronization profile. If data throughput is expected to approach the practical limit of 100 Mbps rather than remain below it, engineers should assess a higher-speed Ethernet controller instead.
Recomendado
Communication Equipment
The KSZ8441HLI can serve communication equipment that connects embedded logic to a 10/100 Ethernet segment and needs IEEE 1588v2 synchronization for event correlation. The device is suited to industrial communication equipment rather than data-center or broadband applications, particularly where a single 100 Mbps port is sufficient and timing consistency adds value. Its internal MAC and PHY reduce external component count and provide a defined platform for industrial networking. Deployment planning should include supported media, transformer or magnetics selection, isolation strategy, firmware support, startup sequencing, and thermal verification. The exact LQFP pin allocation must be followed exactly because unused and reserved pins may have defined electrical requirements.

Notas de diseño
Treat the 64-LQFP footprint as a function-specific, pin-sensitive land pattern. Verify every signal, power, ground, reserved, and no-connect position against the current manufacturer pinout before releasing Gerber files; do not infer assignments from a generic 64-LQFP library or from another Ethernet controller. Arrow identifies the HLI ordering code as tray packaged, so the PCB assembly process should also be confirmed against the selected distributor inventory rather than assumed to be reel packaged.
Reserve routing and copper area for the Ethernet physical interface and its magnetic network exactly as required by the manufacturer layout guidance. Keep high-speed or clock-sensitive traces short, maintain the specified return paths, and separate noisy digital switching paths from clock and media-related conductors. The supplied records do not provide trace-length limits or component placement distances, so those values must be taken from the KSZ8441 hardware design guidance rather than guessed.
IEEE 1588v2 performance depends on a predictable clock and network infrastructure, not merely the presence of the controller. Validate reference-clock jitter, timestamping behavior, packet-path latency, switch support, and synchronization topology at the system level. If the equipment requires accuracy beyond the values stated in the manufacturer documentation, characterize it with the intended network and cabling instead of assuming that all IEEE 1588v2 implementations provide equal synchronization quality.
