Procurement Notes

Verify component authenticity against official Freescale Semiconductor documentation. Confirm that the part number suffix matches the specific silicon revision and packaging requirements. Ensure compatibility with existing system power supplies and thermal management solutions before integration. Check for end-of-life status or alternative sourcing options if long-term availability is required.

Selection Notes

Select this component when a PowerPC 603e-based solution with up to 450 MHz performance is required. Consider the TBGA-480 package constraints for PCB layout. Evaluate the 1.45 V to 1.6 V core voltage requirements against available power rails. Compare cache sizes and interface options with other members of the PowerQUICC II family if different performance levels are needed.

Part Context

This processor is part of the broader PowerQUICC II family, which includes variants like the MPC8270 and MPC8275. These devices share common hardware specifications and architectural foundations but differ in clock speeds and peripheral configurations. The MPC8280 represents a higher-performance option within this lineage, targeting demanding communication and networking applications.

Replacement Considerations

Consult official datasheets for cross-referencing with MPC8270 or MPC8275 variants. Verify pinout and electrical compatibility before substituting. No direct public substitute part numbers are confirmed for this specific model.
