BCM53162XMB1KLFBG

Overview

The BCM53162XMB1KLFBG is a high-performance Ethernet switch integrated circuit from Broadcom's RoboSwitch family. It features eight 10/100/1000 Mbps ports and one 10 Gbps uplink port, designed for robust network switching applications. The device supports IEEE 802.3 standards and includes an industrial temperature range variant (-40°C to +85°C) indicated by the 'I' suffix in the part number. It integrates GPIO, I2C, MII, and SPI interfaces for system control and monitoring.

Feature Summary

• Supports eight Gigabit Ethernet ports with integrated PHYs for direct copper connectivity.
• Includes a dedicated 10 Gbps uplink interface for high-bandwidth aggregation.
• Industrial temperature rating ensures reliable operation in harsh environments.
• Integrates management interfaces including GPIO, I2C, MII, and SPI.

Applications

• Enterprise core and distribution layer switches
• Industrial networking equipment requiring wide temperature tolerance
• High-density access points with 10G uplinks
• Telecommunications infrastructure

Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to confirm temperature range and package type. Ensure compatibility with existing PCB footprints and thermal management solutions. Confirm RoHS compliance status through official documentation before procurement.

Selection Notes

Select this component when both eight Gigabit ports and a 10 Gbps uplink are required within a single IC. Consider the industrial temperature grade if the deployment environment exceeds standard commercial limits. Evaluate power consumption requirements relative to the integrated PHY capabilities.

Part Context

This model belongs to the Broadcom BCM531xx series of RoboSwitch devices. These chips are optimized for cost-effective, high-port-count switching solutions. The BCM53162 specifically targets applications needing a balance of port density and high-speed uplink capability without external PHY components.

Replacement Considerations

Check for pin-compatible alternatives within the same Broadcom family, such as the BCM53156 or BCM53158, depending on whether fewer ports or different uplink configurations are acceptable. Verify that any substitute maintains the required industrial temperature rating and interface support.
