KSZ9893RNXC-TR

Controllers Overview

The KSZ9893RNXC-TR is a 3-port Gigabit Ethernet switch manufactured by Microchip Technology, housed in a 64-pin VQFN package. It integrates two 10/100/1000BASE-T PHYs and one configurable MAC port supporting RGMII, MII, or RMII interfaces. The device operates within an industrial temperature range of -40°C to +85°C and supports data rates of 10 Mb/s, 100 Mb/s, and 1 Gb/s. Power supply requirements include 1.8V, 2.5V, and 3.3V for I/O and analog/digital domains. Management interfaces include SPI, I2C, MIIM, and in-band access.

Controllers Feature Summary

• Non-blocking wire-speed switching fabric with full VLAN and QoS support
• Integrated Energy-Efficient Ethernet (EEE) and Wake-on-LAN capabilities
• Configurable external MAC port for direct host processor connection
• Comprehensive management via SPI, I2C, MIIM, and in-band protocols

Controllers Applications

• Industrial control and automation switches
• VoIP infrastructure switches
• Broadband gateways and firewalls
• Security and surveillance systems

Controllers Procurement Notes

Verify the specific suffix 'X' against official documentation to confirm if it denotes a distinct variant or packaging option compared to standard listings. Ensure compatibility with industrial temperature specifications (-40°C to +85°C) required for your application environment. Confirm that the 64-pin VQFN package dimensions align with your PCB footprint design guidelines.

Controllers Selection Notes

Select this component when a managed Gigabit switch with integrated PHYs and a flexible host interface is required. It is suitable for designs needing IEEE 802.1X authentication, ACL filtering, and advanced power management features like EEE. Consider the 64-pin VQFN package constraints and ensure adequate thermal dissipation for the exposed pad ground connection.

Controllers Part Context

This part belongs to the KSZ9893R series of highly integrated Layer-2+ managed switches. It combines switching logic with physical layer transceivers to reduce system complexity. The device is designed to offload host processing through hardware-accelerated forwarding and filtering functions.

Controllers Replacement Considerations

Consult Microchip documentation for verified substitutes. Cross-reference pinouts and electrical characteristics carefully when considering alternative components from other manufacturers.
