KSZ8794CNXIC-TR

Controllers Overview

The KSZ8794CNXIC-TR is a Layer 2-managed, four-port Ethernet switch integrating three 10/100BASE-T/TX MAC/PHYs and one Gigabit GMAC. It supports RGMII, MII, and RMII interfaces for the uplink port. The device features a non-blocking store-and-forward fabric with a 64 KB frame buffer and a 1024-entry forwarding table. Operating voltage ranges from 1.8 V to 3.3 V, with a core supply of 1.2 V. Maximum power consumption is 107 mA or 110 mA depending on configuration. It operates within commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges.

Controllers Feature Summary

Controllers Procurement Notes

Verify the specific suffix IC against the manufacturer's official documentation to confirm package type and temperature range. Ensure the ordering code matches the required reel or cut tape format. Confirm RoHS compliance status through the latest datasheet revision. Check for any recent product change notifications that may affect pinout or electrical characteristics before finalizing procurement.

Controllers Selection Notes

Select this component when a managed switch solution is required with integrated copper transceivers and a Gigabit uplink. Consider the available interface options (RGMII, MII, RMII) for host connectivity. Evaluate power requirements against the specified maximum current draw. Ensure the operating temperature range aligns with the target application environment.

Controllers Part Context

The KSZ8794CNX belongs to the Microchip KSZ8794 series of integrated Ethernet switches. It is designed to replace discrete switch and PHY solutions by combining multiple functions into a single chip. This integration reduces system cost and board space while maintaining high performance and feature richness for networked applications.

Controllers Replacement Considerations

Consult the official Microchip compatibility matrix for verified substitutes. Generic cross-references are not sufficient; only part numbers explicitly listed as replacements in public documentation should be considered.
