KSZ8893MQL

Controllers Overview

The KSZ8893MQL is a highly integrated Layer 2 managed switch designed for low port count, cost-sensitive 10/100 Mbps Ethernet systems. It features three MAC units and two 10/100 transceivers with patented mixed-signal low-power technology. The device includes a high-speed non-blocking switch fabric, a dedicated address lookup engine, and on-chip frame buffer memory. Both PHY units support 10BASE-T and 100BASE-TX, while one PHY additionally supports 100BASE-FX. It operates within a commercial temperature range of 0°C to +70°C and utilizes a single 3.3V power supply.

Controllers Feature Summary

• Integrated 3-Port 10/100 Ethernet Switch compliant with IEEE 802.3u standard
• Comprehensive configuration access via SMI, MIIM, SPI, I2C, and EEPROM interfaces
• Advanced switching capabilities including VLAN, QoS prioritization, and IGMP snooping
• Low power dissipation with hardware power-down and per-port software power-save modes

Controllers Applications

• Media Converter
• VoIP Phone
• SOHO Residential Gateway
• Wireless LAN Access Point + Gateway
• Standalone 10/100 Switch

Controllers Procurement Notes

Verify the specific ordering suffix to confirm the operating temperature grade and package type. The 'MQL' designation indicates a commercial temperature range (0°C to +70°C) in a 128-pin PQFP lead-free package. Confirm that the intended application environment aligns with these commercial specifications rather than industrial or automotive grades.

Controllers Selection Notes

Select this component for applications requiring a compact, cost-effective Layer 2 managed switch solution. Ensure the design accommodates the 128-pin PQFP footprint and provides the necessary 3.3V power supply. Verify interface compatibility with the host CPU using the available SPI, I2C, MII, RMII, or SNI options.

Controllers Part Context

This part belongs to the KSZ8893 family of integrated switches. Variants include the KSZ8893MQLI for industrial temperatures (-40°C to +85°C) and the KSZ8893MQL AM for automotive-grade requirements. A ball grid array version, KSZ8893MBL, is also available in commercial and industrial grades.

Controllers Replacement Considerations

Direct replacements include the KSZ8893MQLI for industrial temperature operation and the KSZ8893MBL for BGA packaging. Cross-family upgrades may involve the KSZ8873 series, though pinouts and feature sets differ.
