BCM56440XB0IFSBLG

BCM56440XB0IFSBLG is a Broadcom Ethernet switch IC (BCM56440 family). It’s a high‑performance system‑on‑chip used in enterprise and service‑provider switches, integrating a multi‑port switch fabric, a processor interface, and hard/soft network features. It typically supports L2/L3 switching, QoS, VLANs, ACLs, IP routing, multicast, and device management, enabling high‑density, feature‑rich switch implementations. The suffix “XB0IFSBLG” is a specific package/stepping/lot code used for manufacturing and BOM identification; it does not change the core silicon functionality. For exact specifications (port counts and types, speeds, memory, CPU interfaces, SDK compatibility), consult Broadcom’s BCM56440 datasheet and hardware user guide, or contact Broadcom support.

BCM56440XB0IFSBLG is Broadcom’s StrataXGS switch SoC. Key features (typical for this family) include:
- High-density, 40-port Ethernet switch with line-rate, non-blocking fabric (configurable 1G/10G per port).
- L2/L3 forwarding with hardware acceleration for switching and basic routing.
- VLAN support: 802.1Q, QinQ, and VLAN routing.
- QoS and traffic management: multiple egress queues, shaping, policing, and hierarchical QoS.
- Security and policy: hardware ACLs and related security features.
- Multicast support: IGMP/MLD snooping and multicast routing capabilities.
- IPv4/IPv6 forwarding with basic routing features.
- Hardware timestamping (IEEE 1588 PTP v2) for precise timing.
- Large MAC address table and TCAM for ACLs.
- Management/control plane interfaces to host CPU (standard management options).
- Efficient power design and integrated peripherals; available in BGA package (revision B0, IFSBLG).
Note: exact port mix, memory sizes, and feature set can vary by revision; consult the specific datasheet for the B0 IFSBLG variant.
