Procurement Notes

Verify silicon revision compatibility before integration; this document covers revision 1.1 silicon and earlier. Confirm that the ordering suffix matches the required package type and temperature range. Check for specific errata updates relevant to the silicon version in use. Ensure power sequencing meets the specified requirements for PORESET and supply voltages to guarantee proper initialization.

Selection Notes

Select this processor for applications requiring high-performance embedded networking and secure communications. Consider the 672-pin LBGA package constraints during PCB layout. Evaluate thermal dissipation requirements based on the operating frequency and load conditions. Verify software compatibility with existing Power Architecture implementations if migrating from previous generations.
