Procurement Notes

Verify the specific silicon revision level required for your design, as documentation differs between earlier revisions and revision 3.0 silicon. Confirm that the ordering suffix matches the intended hardware specifications. Ensure compatibility with existing software drivers developed for the PowerPC e300 architecture before finalizing procurement decisions.

Selection Notes

Select this component when high integration of networking and security features is required within a single chip. It is suitable for applications needing robust encryption offloading and multiple high-speed communication interfaces. Consider the thermal dissipation requirements associated with the 667 MHz operation in your system design.

Part Context
