KSZ8993MLI

Specialized ICS Overview

The KSZ8993MLI is a Layer 2 managed switch IC from Microchip Technology, housed in a 128-pin PQFP package. It integrates three MAC units and two 10/100 Mbps PHY transceivers compliant with IEEE 802.3u. Port 1 supports 10BASE-T, 100BASE-TX, and 100BASE-FX standards, while Port 2 supports 10BASE-T and 100BASE-TX. The device operates on dual power supplies: a 1.8V core voltage (VDDC) and a 3.3V I/O/transceiver voltage (VDDIO). It features a non-blocking switch fabric with store-and-forward architecture, supporting full-duplex flow control, VLAN tagging, and QoS prioritization.

Specialized ICS Feature Summary

• Integrated 3-Port 10/100 Ethernet Switch with two PHYs and three MACs
• Supports 10BASE-T, 100BASE-TX, and 100BASE-FX (Port 1 only)
• Dual supply operation: 1.8V Core and 3.3V I/O/Transceiver
• Comprehensive management via SMI, MIIM, SPI, and I2C interfaces

Specialized ICS Applications

• Broadband Gateway/Firewall/VPN
• Integrated DSL or Cable Modem Multi-Port Router
• Wireless LAN Access Point + Gateway
• Residential and Enterprise VoIP Gateway/Phone
• Standalone 10/100 Switch

Specialized ICS Procurement Notes

Verify the specific suffix 'I' against official documentation to confirm industrial temperature range specifications. Ensure the design accommodates the required 1.8V and 3.3V power rails as this model is not single-supply. Confirm package compatibility with the 128-PQFP footprint during procurement planning.

Specialized ICS Selection Notes

Select the KSZ8993MLI when managed switch capabilities are required for low port count applications. Choose this part over the KSZ8993M if industrial temperature ratings are necessary. Note that the KSZ8993ML variant offers single-supply operation; ensure the correct power domain requirements are met before selection.

Specialized ICS Part Context

The KSZ8993MLI belongs to the KSZ8993 series of integrated switches. It shares the same functional architecture as the KSZ8993M but includes an 'I' suffix indicating industrial temperature grade availability. It serves as a cost-effective solution for Fast Ethernet systems requiring Layer 2 management features without external processors.
