Controllers Procurement Notes

Verify the exact ordering suffix against Microchip's official documentation to confirm package type and temperature range. Confirm interface width requirements match the specific variant ordered. Check for any recent datasheet revisions that may affect pin compatibility or electrical characteristics before finalizing procurement.

Controllers Selection Notes

Select this component when a single-port Fast Ethernet solution with non-PCI bus interfaces is required. Ensure the host system supports either 8-bit or 16-bit data buses as specified by the model suffix. Consider the industrial temperature grade if operating in environments exceeding standard commercial limits.

Controllers Part Context

This part belongs to the KSZ8841 series of single-port Ethernet MAC controllers. It is designed for applications requiring efficient integration of Fast Ethernet connectivity without the overhead of PCI interfaces. The series offers various packaging options and interface widths to accommodate different system architectures.

Controllers Replacement Considerations

Consult Microchip's official cross-reference tools for verified substitutes. Ensure any replacement maintains compatible interface types and voltage levels. Verify that alternative components support the same IEEE 802.3u standards and feature sets required by the application.
