KSZ8841-16MVLI-TR

Controllers Overview

The KSZ8841-16MVLI-TR is a single-port Ethernet MAC controller with a non-PCI interface, compliant with IEEE 802.3u standards. It supports 10BASE-T and 100BASE-TX speeds with auto-negotiation for full- and half-duplex modes. The device features an 8-bit or 16-bit generic host processor interface, 8 KB of internal memory for RX/TX FIFO buffers, and a single 25 MHz reference clock. It operates on a single 3.3V power supply with 5V tolerant I/O buffers. The component is available in a 128-pin LQFP package and supports an industrial temperature range from -40°C to +85°C.

Controllers Feature Summary

• Supports Wake-on-LAN functionality including Magic Packet and Network Link State technologies.
• Includes Microchip LinkMD cable diagnostic capabilities to determine cable length and diagnose faults.
• Features HP Auto MDI-X crossover with disable/enable options to eliminate straight or crossover cable differentiation.

Controllers Applications

• Video Distribution Systems
• High-End Cable, Satellite, and IP Set-Top Boxes
• Industrial Control in Latency-Critical Applications

Controllers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Ensure the procurement channel provides valid RoHS compliance data. Confirm that the TR suffix indicates tape and reel packaging if required by assembly processes. Cross-reference the manufacturer part number with current datasheet revisions to ensure silicon compatibility.

Controllers Selection Notes

Select this component when a single-port Fast Ethernet solution with a non-PCI CPU interface is required. The 16-bit bus option suits systems needing wider data paths than 8-bit designs without the complexity of 32-bit interfaces. Verify that the industrial temperature range meets environmental requirements. Ensure the host processor can support the necessary synchronous or asynchronous bus protocols defined in the interface specifications.

Controllers Part Context

This part belongs to the KSZ8841M series of single-port Ethernet MAC controllers. It is designed as a mixed analog/digital device offering low-power CMOS performance. The MVLI suffix denotes the industrial temperature grade variant housed in a 128-pin LQFP package. It serves as a cost-effective alternative to PCI-based controllers for embedded applications requiring direct CPU interfacing.

Controllers Replacement Considerations

Consult the official datasheet for cross-referencing with other members of the KSZ8841 family. Verify pinout and electrical characteristics before substituting with variants like the KSZ8841-32MVLI or KSZ8841-16MVL. Ensure interface width and temperature ratings match the original design requirements.
