KSZ8842-16MBLI-TR

Controllers Overview

The KSZ8842-16MBLI-TR is a two-port Ethernet switch with a non-PCI CPU interface, compliant with IEEE 802.3u standards. It supports 10BASE-T and 100BASE-TX data rates at 10 Mb/s and 100 Mb/s respectively. The device operates on a single 3.3V power supply with a minimum voltage of 3.1V and a maximum of 3.5V. It features an LFBGA-100 package and supports full-duplex and half-duplex modes. The operating temperature range extends from -40°C to +85°C.

Controllers Feature Summary

• Fully managed Layer-2 switching with non-blocking fabric and store-and-forward architecture
• Supports IEEE 802.1Q VLAN, 802.1p/Q QoS, and IGMP/MLD snooping for traffic management
• Includes LinkMD cable diagnostics and HP Auto-MDIX capabilities
• Configurable as a low-latency repeater or switch with dynamic buffer memory

Controllers Applications

• Video Distribution Systems
• Industrial Control in Latency Critical Applications
• Security and Surveillance Cameras
• Voice over IP (VoIP) and Analog Telephone Adapters

Controllers Procurement Notes

Verify the component against official Microchip datasheet DS00003459A to confirm pinout compatibility and electrical specifications. Ensure the ordering suffix matches the required bus width and temperature grade. Cross-reference part numbers with authorized distributors to validate authenticity and current availability status before finalizing procurement decisions.

Controllers Selection Notes

Select this model for applications requiring a fully managed 2-port switch with a generic host processor interface. The -16 suffix indicates support for 8-bit or 16-bit bus designs. Consider the industrial temperature range (-40°C to +85°C) for harsh environments. Verify that the LFBGA-100 package fits the PCB layout constraints and thermal requirements of the target system design.

Controllers Part Context

This component belongs to the KSZ8842M series of two-port Ethernet switches. It is distinguished by its non-PCI CPU interface, supporting flexible 8-bit, 16-bit, or 32-bit generic host connections. The series integrates MAC units, PHY transceivers, and a high-speed switch fabric into a single chip, serving as a compact solution for embedded Fast Ethernet networking tasks.

Controllers Replacement Considerations

The KSZ8842-32MBLI-TR serves as a direct substitute for systems utilizing a 32-bit bus interface instead of the 8/16-bit configuration. Both parts share identical functional capabilities and pinouts within the LFBGA-100 package family. Verify bus width compatibility when swapping between these variants.
