Procurement Notes

Verify silicon revision compatibility before procurement. This document covers revision 1.1 silicon and earlier; parts ending in 'A' or 'B' require the MPC8347EA specifications. Confirm package type matches design requirements, as electrical characteristics differ between PBGA and TBGA variants. Ensure ordering suffixes align with intended voltage and frequency configurations.

Selection Notes

Select this component for applications requiring high integration of networking and security functions. Verify that the system design supports the required I/O voltages, including 2.5 V for DDR and 3.3 V for PCI. Consider thermal dissipation requirements, as power consumption varies significantly with clock frequency and package type. Ensure software compatibility with the e300 core architecture if migrating from previous generations.

Part Context

The MPC8347E represents an upgrade within the PowerQUICC II series, offering enhanced performance through the e300 core. It builds upon the 603e architecture with improved cache and processing units. The device is designed for embedded networking and communication applications, providing a balance of processing power and peripheral integration suitable for cost-sensitive market segments.

Replacement Considerations

Consult the MPC8347EA datasheet for silicon revisions 3.0 and later, which correspond to orderable part numbers ending in A or B. Direct functional replacements within the same family include the MPC8349E and MPC8358E, though pinouts and specific peripheral counts may vary.
