Procurement Notes

Verify silicon revision level before procurement; this document covers revision 3.x silicon and later. Confirm package type matches the specific suffix requirements. Check RoHS compliance status as older revisions may be non-compliant. Ensure ordering suffixes align with voltage and temperature specifications.

Selection Notes

Select based on required clock frequency and I/O voltage levels. Verify compatibility with existing DDR or DDR2 memory configurations. Consider thermal dissipation requirements for high-frequency operation. Ensure software tools support the Power Architecture e300 core for development.

Part Context

Part of the NXP PowerQUICC II Pro family, designed for networking and embedded applications. Builds upon the e300 SoC platform, offering enhanced performance over previous generations. Provides a highly integrated solution for communication infrastructure and industrial control markets.

Replacement Considerations

MPC8349E: Higher performance variant within the same family. MPC8347E: Similar integration with single PCI interface. Verify pinout and software compatibility when substituting.
