Procurement Notes

Verify the specific ordering suffix VRADD against official NXP documentation to confirm package type and temperature range. Confirm silicon revision compatibility, as specifications differ between revision 1.1 and later versions. Ensure design compliance with absolute maximum ratings for all supply voltages and input signals.

Selection Notes

Select this component for applications requiring high integration of networking and security features on a single chip. Evaluate power dissipation requirements against thermal solutions, as typical power varies significantly with core frequency and package type. Verify software compatibility with existing Power Architecture codebases due to the e300 core architecture.

Part Context

The MPC8347E belongs to the PowerQUICC II Pro family, representing an evolution from the classic PowerQUICC II series. It utilizes a system-on-chip architecture integrating the e300 core with advanced peripherals. This family targets cost-effective, high-performance solutions for emerging network communication and ubiquitous computing markets.

Replacement Considerations

NXP recommends using replacement families such as Power Architecture T1013 or Arm Architecture LS1012/LS1023 for new designs.
