BCM56231B1IFSBLG

Overview

The BCM56231B1IFSBLG is a Gigabit Ethernet switch integrated circuit manufactured by Broadcom Limited. It provides 24 Gigabit Ethernet ports and four high-speed uplink ports, supporting 10/100/1000 Mbps speeds on all interfaces. The device integrates an internal PHY for each port and supports IEEE 802.3az Energy Efficient Ethernet (EEE) to reduce power consumption during low-traffic periods. It features hardware-based QoS, ACLs, and IGMP snooping for traffic management. The component is housed in a BGA package and operates within standard industrial temperature ranges.

Feature Summary

• Integrates 24 Gigabit Ethernet ports with built-in PHY transceivers
• Supports four high-speed uplinks for network aggregation
• Includes hardware-accelerated security and traffic classification capabilities

Applications

• Enterprise access layer switching
• Industrial automation networking
• Telecommunications edge equipment

Procurement Notes

Verify the specific suffix 'BLG' against official Broadcom documentation to confirm pinout compatibility and thermal specifications. Confirm end-of-life status and obsolescence notifications prior to procurement planning. Ensure supply chain sources provide valid traceability for this discontinued component series.

Selection Notes

Select this component when a fixed topology of 24 data ports plus 4 uplinks is required without external PHY components. Evaluate power budget constraints as the device includes integrated PHYs. Compare against newer Broadcom Trident or Tomahawk families if advanced packet processing or higher throughput is needed.

Part Context

This part belongs to the Broadcom BCM56231 family of Gigabit Ethernet switches. It is designed for cost-effective deployment in environments requiring dense port counts. The 'BCM56231' prefix identifies the core silicon generation, while the suffix denotes package and temperature grade variations.

Replacement Considerations

Consult Broadcom's official obsolescence notices for qualified replacement part numbers. No public substitute part numbers are confirmed in available documentation.
