KSZ8863FLL Présentation
An Ethernet switch is a networking semiconductor that connects multiple Ethernet endpoints and forwards frames between ports using integrated physical-layer transceivers, or PHYs. The managed-switch category adds configuration and control functions beyond basic frame forwarding, including port management, VLAN support, QoS priority handling, and CPU-controlled data interfaces. The KSZ8863FLL belongs to the switch-on-a-chip family, combining multiple Ethernet ports and management functions into one device rather than requiring separate discrete PHY and switch components.
Key verified features include a three-port architecture, integrated PHYs, 100BASE-FX fiber support, 10/100BASE-TX copper networking, one MII interface, and CPU control and data interfaces. The product is identified by DigiKey as an Ethernet Switch with a 1.8 V, 2.5 V, or 3.3 V supply option and a 48-LQFP 7 x 7 mm package. Microchip describes the KSZ8863 family as supporting switch management, port and tag-based VLAN, QoS priority, and CPU control, which makes it suitable for compact embedded-network equipment.
The KSZ8863FLL is positioned for industrial, communications, and embedded Ethernet designs that need copper and fiber connectivity in a small package. Its integrated approach can reduce board-level component count and simplify the network architecture compared with a discrete switch implementation. The MII interface allows connection to a host processor or another Ethernet-compatible controller, while I2C or SPI management access supports configuration from a microcontroller or embedded system.
Designers should verify the exact pinout, transceiver requirements, clocking, magnetics, and fiber-interface implementation against the manufacturer datasheet before layout. Although the MLL, FLL, and RLL variants belong to the same KSZ8863 family, their supported interfaces and features differ, so substitution must be checked carefully. The verified data does not provide complete electrical limits, pin names, or pricing, and those values are marked as needed rather than estimated.
This page combines the verified KSZ8863FLL product identity, package information, application positioning, and datasheet references with practical selection guidance. It also distinguishes direct family substitutions from broader Ethernet-switch alternatives that may require PCB, firmware, or interface changes.

Applications typiques
KSZ8863FLL convient pour 6 applications: Compact Industrial Ethernet Gateway, Copper-to-Fiber Network Bridge, Embedded Network Processor Interface, Power-Efficient 10/100 Network Appliance, Industrial Control Panel with Ethernet Connectivity, Cost-Sensitive Consumer Network Device.
Compact Industrial Ethernet Gateway
The KSZ8863FLL fits compact industrial gateways that need three 10/100 Ethernet connections without assembling a large discrete switching subsystem. Its managed-switch functions, integrated PHYs, and low-port-count architecture simplify the network path between a controller, sensors, service equipment, and an uplink. The 48-LQFP 7 x 7 mm package also supports space-conscious equipment, while I2C or SPI management access allows an embedded processor to configure ports and QoS. The exact industrial temperature range is not provided in the verified data and must be checked before use in harsh environments.
Recommandé
Copper-to-Fiber Network Bridge
KSZ8863FLL is well suited to equipment that must transition between copper Ethernet and 100 Mbps fiber. The verified feature set includes 100BASE-FX support, 10/100BASE-TX connectivity, integrated PHYs, and a three-port arrangement. Designers can place the device between local copper endpoints and a fiber uplink, reducing the need for separate fiber-interface hardware. External fiber magnics or transceiver arrangements must follow the manufacturer reference design, and compliance with the target fiber-link specification should be verified.
Recommandé
Embedded Network Processor Interface
The KSZ8863FLL can act as the managed Ethernet layer beside a host processor that needs deterministic port connectivity. Its MII interface provides a standard media-independent connection to compatible processors or controllers, while I2C and SPI provide alternate CPU control paths. This arrangement is useful in embedded equipment where the host handles application traffic and the switch handles local Ethernet ports. Designers should confirm MII timing, clock requirements, supported operating modes, and software-register compatibility against the datasheet.
Recommandé
Power-Efficient 10/100 Network Appliance
The KSZ8863FLL targets low-port-count, cost-sensitive, power-efficient 10/100 Mbps systems, making it appropriate for compact network appliances that do not require gigabit Ethernet. Its integrated three-port switch architecture can reduce the number of separate network components and simplify PCB layout compared with discrete PHY arrangements. The device supports managed features including port- and tag-based VLAN and QoS priority, allowing the appliance to implement basic traffic separation and prioritization. Actual power consumption is not provided in the verified data and should be measured from the datasheet and evaluation board.
Recommandé
Industrial Control Panel with Ethernet Connectivity
KSZ8863FLL can support industrial control panels that connect a controller, service interface, and network uplink while preserving copper and fiber options. The managed-switch capabilities allow port and tag-based VLAN organization, while QoS priority can help protect control or diagnostic traffic from ordinary network traffic. The 48-LQFP package is suitable for a compact controller board, although industrial temperature and EMC requirements must be verified separately. Use the manufacturer reference design to guide magnetics, layout, grounding, and interface protection.
Recommandé
Cost-Sensitive Consumer Network Device
The KSZ8863FLL is suitable for compact consumer or prosumer networking products that need three 10/100 ports and managed-network functions at a modest integration level. Integrated PHYs and the small 48-LQFP package can simplify assembly and reduce board footprint. Its I2C or SPI management interfaces allow a low-cost microcontroller to configure VLAN, port, and QoS behavior instead of requiring a separate full network processor. The verified data does not provide consumer-market temperature, lifecycle, or pricing values, so procurement and qualification should be handled with current distributor data.

- Single-vendor family migration path (vs LAN9354)
Notes de conception
Place the KSZ8863FLL close to the board edge and route Ethernet differential pairs with the shortest practical path. Keep the MII, I2C, SPI, clock, and reset traces away from high-current switching nodes. The verified data confirms a 48-LQFP 7 x 7 mm package, but exact pin locations and recommended layer transitions must be taken from the official datasheet and reference layout.
Decouple each supported supply rail close to the device using the capacitor values and placement specified by Microchip. Do not assume that the 1.8 V, 2.5 V, or 3.3 V options are interchangeable without checking the selected operating mode and external circuitry. Validate sequencing, startup behavior, and current margin against the complete electrical specifications, which were not included in the verified search data.
Do not substitute KSZ8863MLL, KSZ8863RLL, or LAN9354 solely because they are Ethernet switches. The verified Microchip support material confirms that variant substitution requires review, and the fiber interface, host interface, pin functions, and management behavior may differ. Compare the complete pinout, reference design, clocking, and software-control requirements before approving a replacement.
Informations de conformité
The verified Abacus Technologies cross-reference result identifies the KSZ8863FLL as EU RoHS compliant and REACH compliant. Other compliance fields are not provided in the verified data and are therefore marked unknown.
