Procurement Notes

Verify the specific suffix codes against official NXP or Freescale documentation to ensure compatibility with required operating temperatures and voltage levels. Confirm that the procurement source provides genuine components with traceable manufacturing history. Request detailed datasheets and hardware specifications prior to finalizing orders to validate pinout and electrical characteristics match system requirements.

Selection Notes

Select this component when designing systems that require a balance between general-purpose processing power and specialized communication protocol handling. Consider the integration level of memory controllers and peripheral interfaces to reduce board complexity. Evaluate thermal management solutions suitable for the BGA package form factor and the processor's power dissipation profile under maximum load conditions.

Part Context

This microprocessor belongs to the PowerQUICC II family developed by Freescale Semiconductor, now part of NXP Semiconductors. These processors were designed to address the growing demand for embedded networking solutions. The MPC8264 series specifically targets applications needing robust connectivity features alongside efficient code execution for routing and switching tasks in telecommunications infrastructure.

Replacement Considerations

Consult official cross-reference guides from NXP for compatible upgrades within the PowerQUICC lineage. Verify pin-to-pin compatibility and software register-level differences before substituting with newer generation processors. Ensure that any replacement maintains support for existing peripheral configurations and memory architectures used in the original design.
