KSZ8873MLL-AM-TR

Controllers Overview

The KSZ8873MLL-AM-TR is an automotive-grade, fully integrated 3-port 10/100 Mbps Ethernet switch manufactured by Microchip Technology. It features two 10BASE-T/100BASE-TX transceivers and one MII interface for CPU connection. The device operates within a supply voltage range of 1.69 V to 3.465 V and supports data rates of 10 Mb/s and 100 Mb/s. It is housed in a 64-pin LQFP package with SMD/SMT mounting style. The component supports full-duplex and half-duplex modes and includes interfaces such as I2C, MDI-X, MII, MIIM, RMII, SMI, and SPI.

Controllers Feature Summary

• Supports IEEE 802.1q VLAN groups with per-port tag insertion or removal capabilities.
• Includes bypass functionality to maintain switching between ports during processor sleep mode.
• Provides comprehensive QoS support including IPv4/IPv6 classification and rate limiting.
• Features Link MD cable diagnostics for identifying copper cabling faults.

Controllers Applications

• Automotive Ethernet systems
• VoIP phones
• Industrial control networks
• Set-top boxes and game consoles

Controllers Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm the -AM-TR designation corresponds to the Automotive Grade qualification and Tape & Reel packaging format. Ensure compatibility with the required industrial temperature range specifications before finalizing procurement orders.

Controllers Selection Notes

Select this component when an automotive-rated managed switch with MII connectivity is required. Compare against the standard commercial grade KSZ8873MLL if environmental constraints are less stringent. Verify that the host system can accommodate the 64-pin LQFP footprint and provides the necessary power supply rails.

Controllers Part Context

This part belongs to the KSZ8873 family of integrated 3-port switches. The 'MLL' variant specifically denotes the inclusion of two twisted-pair PHYs and an MII interface. The '-AM-' suffix indicates automotive qualification, while '-TR' specifies the reel packaging method used for automated assembly processes.

Controllers Replacement Considerations

The KSZ8873MML serves as the commercial equivalent. For RMII interface requirements, consider the KSZ8873RLL series. Verify pinout and register compatibility before substituting any cross-family components.
