BCM88802CA1KFSBG

Controllers Overview

The BCM88802CA1KFSBG is a traffic management and packet processing integrated circuit manufactured by Broadcom Limited. It belongs to the StrataXGS Tomahawk series, designed for high-performance data center Ethernet switching applications. The component supports L3 forwarding with a total switching capacity of 3.2 Tbps. It integrates 128 lanes of 25 Gbps SerDes, enabling flexible port configurations such as 32x100GbE, 64x50GbE, or 128x25GbE. The chip features a configurable pipeline with port-to-port latency under 400 ns. It includes hardware offloading for overlay tunnels like VXLAN and MPLS, and supports RoCE/RoCEv2 for storage networking.

Controllers Feature Summary

• Integrates 128 low-power 25 Gbps SerDes lanes for native 25G/100G connectivity
• Provides hardware acceleration for network virtualization overlays including VXLAN, NVGRE, and MPLS
• Supports RoCE and RoCEv2 protocols optimized for storage area networks
• Includes BroadView telemetry for real-time flow statistics and link health monitoring

Controllers Applications

• Data Center Top-of-Rack (ToR) switches connecting 25G servers
• Leaf-Spine architecture interconnects using 100G uplinks
• High-density blade switch systems requiring 3.2 Tbps throughput
• Storage Area Networks utilizing RDMA over Converged Ethernet

Controllers Procurement Notes

Verify the specific silicon stepping indicated by the suffix B0 against the target system requirements, as this denotes the manufacturing revision. Confirm that the KF package type matches the PCB footprint design rules for large FBGA assemblies. Ensure the supply chain source provides valid traceability documentation for this active component. Check compatibility with the required SDK version for software-defined networking features.

Controllers Selection Notes

Select this component when designing systems requiring native 25G SerDes integration without external retimers. It is suitable for architectures needing 3.2 Tbps non-blocking bandwidth in a single ASIC. Consider the thermal dissipation requirements associated with the high pin-count FBGA package. Evaluate the need for HiGig expansion if chassis-based scalability beyond single-chip capacity is required.

Controllers Part Context

This part is a member of the Broadcom StrataXGS Tomahawk family, representing an early generation of high-throughput switching silicon. It was released around 2014 on a 28 nm process node. The BCM88802 variant specifically focuses on traffic management capabilities within this lineage, serving as a foundational solution for early 25G Ethernet deployments before subsequent generations introduced higher speeds.

Controllers Replacement Considerations

Direct functional replacements are limited due to proprietary architecture differences. Later generations such as the BCM56970 or BCM56980 offer increased throughput but require significant redesign. No direct cross-compatible substitutes are publicly confirmed for this specific legacy part number.
