BCM53106MKFBG

Overview

The BCM53106MKFBG is a Broadcom Limited Ethernet IC classified as an ultra-low power Gigabit Ethernet switch. It operates within the RoboSwitch family and utilizes an FBGA-212 package for surface-mount installation. The component supports 10BASE-T, 100BASE-TX, and 1GBASE-T standards with four integrated transceivers. Electrical parameters include a minimum operating voltage of 950 mV and a maximum of 3.47 V, with a maximum supply current of 183.3 mA. The device functions in full-duplex mode and interfaces via RGMII and SGMII protocols. It is rated for an extended industrial temperature range from -45°C to +85°C and holds RoHS3 compliance.

Feature Summary

• Ultra-low power architecture designed for energy-efficient network applications
• Integrated four-port Gigabit Ethernet switching capability
• Extended industrial temperature rating suitable for harsh environments

Applications

• Industrial automation control systems requiring robust connectivity
• Energy-efficient embedded networking gateways
• Compact IoT edge devices with strict power constraints

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, and distributors may not stock new units. Engineers must verify obsolescence status through official Broadcom channels before finalizing designs. Alternative sourcing should focus on verified surplus suppliers or qualified replacement components that meet identical electrical and mechanical specifications.

Selection Notes

Select this part only if the design requires a low-pin-count, ultra-low power Gigabit switch with industrial temperature tolerance. Verify that the system power budget aligns with the 183.3 mA maximum current draw. Ensure the PCB layout supports the FBGA-212 package dimensions. Confirm that RGMII or SGMII interface compatibility exists with the host processor. Consider lifecycle risks due to EOL status when planning long-term production runs.

Part Context

The BCM53106MKFBG belongs to Broadcom's RoboSwitch portfolio, which targets cost-sensitive and power-constrained networking segments. It serves as a specialized solution for compact switches where footprint and energy consumption are critical. The 'M' suffix typically denotes specific packaging or temperature variants within the broader BCM5310x series. This component bridges basic Fast Ethernet needs with modern Gigabit capabilities in small form factors.

Replacement Considerations

Official substitutes include the BCM53106MIFBG, which shares similar core switching functionality but may differ in package type or thermal characteristics. Designers should consult the latest Broadcom obsolescence notices for recommended cross-references. Any replacement must match the 4-port Gigabit specification and industrial temperature range to ensure functional parity.
