BCM53101EKMLG

Overview

The BCM53101EKMLG is a seven-port managed 10/100 RoboSwitch fabricated in 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, 2 KB maximum frame size, and 4K-entry VLANs. Key features include four CoS queues for QoS, IEEE 802.1x security, BroadSync HD for AVB support, and rate limiting. Power consumption is less than 0.7W at full power.

Feature Summary

• Integrates five Fast Ethernet transceivers and MACs with an additional Gigabit Ethernet MAC for CPU connectivity.
• Supports Layer 2+ features including 4K-entry VLANs, IGMP/MLD snooping, and port mirroring.
• Provides traffic management through ingress rate limiting, egress shaping, and four CoS priority queues.
• Incorporates low-power green modes such as auto-power down, sleep, and deep sleep.

Applications

• Next-generation six Fast Ethernet plus one Gigabit Ethernet switches
• Multimedia and data traffic networks requiring guaranteed bandwidth
• Managed industrial or enterprise access switches

Procurement Notes

Verify the specific suffix EKMLG against the manufacturer datasheet to confirm package type and temperature range. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure the ordering information matches the exact component designation required for the design.

Selection Notes

Select this component when a highly integrated L2+ switch solution is needed with minimal external components. It is suitable for designs requiring both Fast Ethernet ports and a Gigabit uplink. Consider the 65 nm process benefits for power efficiency compared to older generations like the BCM5325E.

Part Context

The BCM53101 series serves as a feature-enhanced successor to the BCM5325E RoboSwitch. It combines high-speed switching functions into a single chip using advanced 65 nm technology. This integration reduces system cost and board space while providing enhanced Layer 2 capabilities for modern networking applications.

Replacement Considerations

The BCM53101EIMLG is a related variant within the same family. Verify pinout compatibility and functional equivalence before substitution. Check if the specific suffix differences affect operating temperature or packaging requirements.
