• Dual three-speed Ethernet controllers supporting GMII, RGMII, MII, and TBI interfaces
• USB dual-role and multi-port host controller functionality with EHCI compatibility
• Local bus controller supporting multiple chip selects and programmable protocol engines

Applications

• Ethernet routers and switches
• Wireless LAN devices
• Network attached storage systems
• Industrial control equipment

Procurement Notes

Verify silicon revision level against ordering suffixes; this document covers revision 1.1 and earlier. Confirm package type compatibility, as electrical characteristics differ between PBGA and TBGA variants. Ensure I/O voltage tracking requirements are met during power sequencing. Check for product end-of-life status and availability of replacement families before finalizing procurement plans.

Selection Notes

Select this component for applications requiring high integration of networking and security functions within a Power Architecture ecosystem. Consider the specific memory interface requirements, noting that DDR data rates vary by package type. Evaluate thermal dissipation needs based on operating frequency and load conditions. Verify software compatibility with existing PowerPC e300 codebases if migrating from older generations.

Part Context

This device belongs to the MPC8347E PowerQUICC II Pro family, representing an upgrade to the legacy PowerQUICC II series. It utilizes the scalable e300 system-on-chip platform, offering enhanced performance over previous 603e-based processors while maintaining software compatibility. The family targets cost-effective solutions for embedded networking and storage markets.

Replacement Considerations

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