BCM53101PIMLG

Overview

The BCM53101 is a seven-port managed 10/100 RoboSwitch fabricated in a 65 nm LP process. It integrates five 10/100 MACs with five on-chip 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 at full power, utilizing Green features like auto power down and deep sleep modes.

Feature Summary

• Highly integrated design combining MACs, PHYs, and switch fabric in a single chip
• Supports advanced Layer 2+ features including 802.1Q VLAN and IGMP/MLD snooping
• BroadSync HD capability for Audio Video Bridging traffic control
• Low-power architecture with multiple green energy-saving modes

Applications

• Next-generation six Fast Ethernet plus one Gigabit Ethernet switches
• Industrial and enterprise managed switches requiring L2+ features
• Networked electronic devices requiring guaranteed bandwidth and time-sync for AV traffic

Procurement Notes

Verify the specific ordering suffix against the official Broadcom datasheet to confirm package type and temperature range. Ensure compatibility with required interface standards such as RGMII or MII for the gigabit port. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when a high level of integration is required to reduce PCB space and BOM cost. It is suitable for designs needing managed switching capabilities without external PHYs. Consider the 65 nm process benefits for thermal management and power efficiency in compact enclosures.

Part Context

This device is an evolution of the industry-leading BCM5325E RoboSwitch, offering enhanced L2+ features. It is optimized for L2 switching and combines packet buffers, address management, and a non-blocking switch fabric into a highly efficient single-chip solution for modern network infrastructure.

Replacement Considerations

The BCM5325E is identified as the predecessor model. Verify functional equivalence regarding port count and feature set before substitution. Check for differences in pinout compatibility and power requirements between the legacy and current generation parts.
