Microprocessors Procurement Notes

Verify availability status carefully as this specific part number may be discontinued or subject to limited distribution channels. Confirm that the FC-CBGA-1023 package footprint matches your PCB design constraints. Ensure compliance with RoHS directives by checking the specific suffix details against current manufacturer declarations. Validate lead times through authorized distributors due to potential supply chain variations for legacy components.

Microprocessors Selection Notes

Select this component when a robust PowerPC-based solution with hardware floating-point support is required for network processing tasks. Consider the 1.25 GHz speed and 1 MB L2 cache for applications demanding deterministic real-time performance. Evaluate the 1023-ball BGA package for board space limitations and thermal dissipation requirements compared to lower-pin-count alternatives in the same family.

Microprocessors Part Context

This microprocessor belongs to the MPC8640 integrated host processor family designed for high-performance embedded networking. It serves as a successor to earlier PowerQUICC III devices, offering enhanced processing capabilities and expanded peripheral connectivity. The device is engineered for demanding environments requiring reliable data handling and secure communication protocols in industrial and telecom sectors.

Microprocessors Replacement Considerations

Consult official NXP documentation for confirmed substitute part numbers within the MPC8640 series. Verify pin compatibility and electrical specifications before transitioning to alternative revisions or upgraded models.
