Procurement Notes

Verify silicon revision compatibility before procurement. This document covers revision 1.1 silicon and earlier. Parts ending in A or B indicate revision 3.0 silicon or later, which requires the MPC8347EA Hardware Specifications datasheet. Confirm ordering suffixes match the required silicon version for functional accuracy.

Selection Notes

Select this component for networking applications requiring integrated security and high-speed Ethernet connectivity. Ensure board design accommodates the specific voltage requirements for core, PLL, and I/O supplies. Verify that the system bus clock and core frequency configurations align with the thermal dissipation limits defined in the power characteristics section.

Part Context

This part belongs to the MPC8347E PowerQUICC II Pro family. It is designed as a next-generation upgrade to the PowerQUICC II series, offering enhanced performance through the e300 core and increased integration of peripherals like DDR controllers and security engines compared to previous generations.

Replacement Considerations

For new designs, consider replacement families such as Power Architecture T1013 or Arm Architecture LS1012/LS1023. Direct substitutes within the same legacy family may require verification of silicon revision differences and updated hardware specifications.
