Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and lead content. Confirm that the intended application environment falls within the specified ambient temperature and voltage operating conditions. Ensure proper thermal management is implemented as per the junction-to-ambient resistance values provided in the datasheet.

Selection Notes

Select this component for applications requiring high-performance layer 2 forwarding and control plane processing. Consider the available package options if different pin counts or lead types are required. Evaluate the clock configuration modes to ensure the desired CPU and CPM frequency ratios meet system timing requirements.

Part Context

This part belongs to the MPC8280 family of PowerQUICC II processors manufactured by NXP Semiconductors (formerly Freescale). The family utilizes HiPerMOS7 0.13-micron process technology. Other members include the MPC8275 and MPC8280, which offer varying levels of peripheral integration such as additional UTOPIA ports or Transmission Convergence layers.

Replacement Considerations

Consult the official datasheet for alternative devices within the MPC82xx family. Verify software compatibility and pinout differences before substituting with other variants like the MPC8275 or MPC8280.
