Procurement Notes

Verify silicon revision compatibility; this document covers revision 3.x silicon and later. Confirm voltage requirements for specific I/O domains including DDR, Ethernet, and PCI. Ensure power sequencing adheres to specifications to prevent excessive current draw during startup. Check for updated errata or product summaries on the manufacturer's website before finalizing design integration.

Selection Notes

Select this component for high-performance networking applications requiring integrated security and multiple high-speed interfaces. Consider the 672-pin LBGA package size and thermal dissipation requirements. Evaluate the need for DDR versus DDR2 support based on system latency and cost constraints. Verify software compatibility with existing Power Architecture codebases.

Part Context
