BCM53101MKMLG

Overview

The BCM53101MKMLG is a seven-port managed Fast Ethernet switch fabricated on a 65 nm LP process. It integrates five 10/100 MACs with five 10/100 PHYs, one 10/100 MAC via MII/RvMII/RMII, and one 10/100/1000 MAC via RGMII/MII/RvMII/RMII. The device supports a 2K MAC address table, 4K-entry VLANs, and four CoS queues for QoS. Power consumption is less than 0.7W in full power mode.

Feature Summary

• Integrates five 10/100 MACs with five 10/100 PHYs and an additional Gigabit MAC for CPU connectivity
• Supports 4K-entry VLANs, 802.1x security, and IGMP/MLD snooping for advanced Layer 2 management
• Features BroadSync HD for audio/video traffic synchronization and low-power green modes

Applications

• Next-generation six Fast Ethernet plus one Gigabit Ethernet switches
• Multimedia and data traffic networks requiring L2+ features
• Networked electronic devices needing guaranteed bandwidth and time-sync

Procurement Notes

Verify the specific MKMLG suffix against official Broadcom documentation to confirm package type and temperature range. Ensure compatibility with 1.2V core and 2.5V/3.3V I/O requirements during integration.

Selection Notes

Select this component for designs requiring high integration of Fast Ethernet ports with Gigabit uplink capabilities. Consider its low power profile and extensive L2 features for cost-effective managed switch implementations.

Part Context

This part belongs to the BCM53101 RoboSwitch family, optimized for L2 switching. It serves as a feature-enhanced successor to the BCM5325E, offering lower power consumption and higher port density within a single chip solution.

Replacement Considerations

The BCM5325E is a predecessor model. Verify if the reduced port count or lack of Gigabit MAC in older replacements meets current design requirements.
