10 Part Numbering and Marking
Ordering information for the parts fully covered by this specification document is provided in
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 10.2, “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.
