• Intelligent wireless LAN access points
• Industrial controllers

Procurement Notes

Verify the specific suffix 'FDA' against official NXP documentation to confirm the exact package type and temperature rating. Confirm that the security engine functionality is present, as standard MPC8315 variants may lack this feature. Ensure compatibility with existing board designs regarding power sequencing and voltage levels before procurement.

Selection Notes

Select this component when a cost-effective, low-power SoC is required for storage or networking applications. It is suitable for designs needing backward software compatibility with previous PowerQUICC processors. Consider the integrated peripherals to reduce external component count. Verify that the 400 MHz performance meets system throughput requirements.

Part Context

This part belongs to the MPC8315E PowerQUICC II Pro family, which extends the capabilities of earlier generations by adding faster interfaces and higher CPU performance. The MPC8315E series addresses market needs for reduced time-to-market and lower power consumption while maintaining a small package size. It serves as a host processor for embedded applications requiring robust I/O capabilities.

Replacement Considerations

Consult official NXP substitution guides for form-fit-function compatible alternatives. Verify if other MPC8315 variants with different suffixes meet the specific electrical and packaging requirements of the current design.
