BCM56442B0IFSBLG

BCM56442B0IFSBLG is a Broadcom Ethernet switch ASIC (forwarding engine) used in data-center and enterprise switches. It integrates a high-performance switch fabric, MACs, and hardware-assisted L2/L3 switching, QoS, ACLs, and virtualization features to deliver scalable, low-latency switching and routing in a single chip. The B0 suffix denotes the silicon revision, while IFSBLG encodes the package/revision/leadframe variant used for ordering.
This device is typically the core forwarding element in fixed or modular switches and is programmed via Broadcom’s SDKs (and can be used with vendor NOSs such as SONiC/OpenSwitch). Exact capabilities—port density, supported speeds (e.g., various Ethernet rates), memory, and feature set—vary by variant and system design. For precise specifications and API compatibility, consult the BCM56442 datasheet and programming guide.

BCM56442B0IFSBLG is Broadcom’s high‑density StrataXGS switch SoC. Exact porting varies by variant, but typical features include:
- Line-rate switching at 40 GbE/100 GbE with a non-blocking fabric
- L2 switching plus IPv4/IPv6 L3 routing (static and dynamic)
- Hardware-based ACLs and QoS with multiple egress queues and shaping
- Large packet buffers for microburst resilience
- VLANs, LACP/Link Aggregation, STP/MSTP, VRF
- Programmable via Broadcom SDK; management via CLI/SNMP; in-band/out-of-band options
- Power/thermal monitoring and reliability features
- Virtualization/fabric features for multi-switch deployments
For exact port counts, supported speeds, and feature granularity, refer to the official BCM56442B0IFSBLG datasheet.

Pin count: 1152-pin BGA (BLG package).
