MPC7457 RISC Microprocessor Hardware Specifications, Rev. 5

Freescale Semiconductor

Part Numbering and Marking

Ordering information for the parts fully covered by this specification document is provided in Section 11.1, “Part

Numbers Fully Addressed by This Document.” Note that the individual part numbers correspond to a maximum

processor core frequency. For available frequencies, contact your local Freescale sales office. In addition to the

processor frequency, the part numbering scheme also includes an application modifier which may specify special

application conditions. Each part number also contains a revision level code which refers to the die mask revision

number. Section 11.2, “Part Numbers Not Fully Addressed by This Document,” lists the part numbers which do not

fully conform to the specifications of this document. These special part numbers require an additional document

called a referred to as a hardware specification addendum.

11.1 Part Numbers Fully Addressed by This Document

Table 23 provides the Freescale part numbering nomenclature for the MPC7457.

Removed support for 1.5 V L3 interface voltage from Tables 3 and 4. 1.5 V I/O voltage is not

supported in current MPC7457 devices.

Added package thermal characteristics values to Table 5, made minor revisions to Section 1.9.8.

Added preliminary AC timing values to Tables 10 and 12.

Added footnotes to Table 17.

Initial release.

Notes:

1. Processor core frequencies supported by parts addressed by this specification only. Parts addressed by a

hardware specification addendum may support other maximum core frequencies.

2. The P prefix in a Freescale part number designates a “Pilot Production Prototype” as defined by Freescale SOP

3-13. These parts have only preliminary reliability and characterization data. Before pilot production prototypes may

be shipped, written authorization from the customer must be on file in the applicable sales office acknowledging

the qualification status and the fact that product changes may still occur while shipping pilot production prototypes.
