BCM56440TB0KFSBLG

BCM56440TB0KFSBLG is Broadcom’s BCM56440 Ethernet switch ASIC (from the BCM56440 family). It’s designed for high-density data-center/enterprise switches and provides line-rate L2/L3 switching with hardware acceleration for common features such as QoS, VLANs, and ACLs, plus routing support. The TB0KFSBLG suffix encodes the package/revision and packaging: TB0 indicates the silicon revision, while KFSBLG denotes the BGA package code (lead-free). In a system, this device is typically paired with external PHYs/SerDes and a control-plane processor to form leaf/spine or edge switch silicon. For exact specs—port counts and speeds (e.g., 40 GbE/100 GbE), memory, throughput, and feature set—refer to the official Broadcom BCM56440 datasheet and product documentation, noting that capabilities can vary by revision and stepping.

Here are typical features of the Broadcom BCM56440TB0KFSBLG (StrataXGS switch family). Exact specs depend on variant and datasheet.
- 40-port Ethernet switch SoC (StrataXGS family) with high-density switching fabric
- Flexible port speeds (1G/10G/40G family variants; uplinks may vary by board)
- L2/L3 switching and routing: IPv4/IPv6, VRF, ACLs, QoS, VLANs, multicast (IGMP/MLD)
- Advanced QoS: hierarchical scheduling, shaping, policing, multiple queues
- Jumbo frame support (up to 9K)
- Hardware timestamping and precise time sync (PTP/IEEE 1588)
- Management and programmability: Broadcom SDK, CLI, SNMP, remote management
- Security and reliability features for control plane; hot-swap/ redundancy options (variant dependent)
Note: Features can vary by exact package/board (TB0KFSBLG). For precise, up-to-date specifications, consult the official Broadcom datasheet for BCM56440TB0KFSBLG.

Pin count: 1216 pins (BGA package, TB0KFSBLG). Function: Broadcom BCM56440 is a StrataXGS/ switch-SoC with integrated Ethernet switch fabric and MAC/SerDes for multiple-port Ethernet switching (used in enterprise/ appliance switches).

Manufacturer: Broadcom Inc. It is a multinational semiconductor and infrastructure software company. Broadcom is principally a fabless semiconductor company, designing chips and outsourcing most manufacturing to contract foundries.
