The BCM63156B1UKFSBG is a network controller and processor IC manufactured by Broadcom Limited. It features a single-core architecture with 35 bonded Gigabit WAN ports and no VoIP or SPU support. The device belongs to the communication and networking ICs subcategory under Broadcom / Avago branding. It is classified as an obsolete product with a discontinued lifecycle status. The component is designed for high-density routing applications requiring extensive physical layer connectivity.
This component is officially discontinued and no longer in production. Availability is restricted to surplus or secondary market channels only. Verify authenticity through authorized distributors or certified refurbishers. Check RoHS compliance documentation carefully, as legacy parts may vary. Confirm package integrity and pin condition before integration into new designs.
Select this part only for maintenance of existing systems requiring exact hardware compatibility. New designs should consider current Broadcom alternatives with similar port counts. Evaluate supply chain stability due to end-of-life status. Ensure firmware tools and ECAD models are available from legacy archives. Compare against newer RoboSwitch series for improved performance and support.
The BCM63156B1UKFSBG is part of Broadcom’s BCM63156 family of network processors. It targets multi-gigabit Ethernet routing applications with fixed port configurations. The B1 suffix indicates specific silicon revision and bonding options. The UKFSBG denotes package type and temperature grade. This model represents a mature solution for high-port-density environments prior to modern SoC integration trends.
No direct public substitute is confirmed. Consider BCM53156XUB1KFBG for switch-centric designs or newer Broadcom NetXtreme series for integrated routing solutions. Verify pinout and software compatibility when migrating.
