Microprocessors Procurement Notes

Verify the specific date code against the manufacturing records, as devices dated 0613 and later require a core voltage of 1.15 V, whereas earlier units operated at 1.1 V. Confirm that the procurement documentation explicitly references the MPC7448ECS01AD addendum to ensure compliance with the revised electrical specifications for this speed grade.

Microprocessors Selection Notes

Select this component when high-performance RISC processing is required within pervasive computing or embedded network environments. Ensure the system power design accommodates the specific 1.15 V core voltage requirement for the 1400 MHz speed grade. Verify that the application supports the 360-pin LGA form factor and operates within the specified thermal envelope.

Microprocessors Part Context

This part belongs to the MPC74xx processor family, representing a significant update utilizing 90nm SOI process technology. It continues the legacy of providing extensive processing performance at lower power levels compared to previous generations. The VS suffix specifically denotes the RoHS-compliant ceramic LGA packaging variant within the broader product line.
