This identifying number contains the following information:
■ Lines 1 and 5: Internal tracking numbers
■ Lines 2 and 3: Part number
For example, TM4C129X on the second line followed by NCZADI3 on the third line indicates
orderable part number TM4C129XNCZADI3. Note that the first letter in the part number indicates
the product status. A T indicates the part is fully qualified and released to production; an X
indicates the part is experimental (pre-production) and requires a waiver. The silicon revision
number is the last number in the part number, in this example, 3. The DID0 register identifies
the version of the microcontroller, as shown in the table below. Combined, the MAJOR and MINOR
bit fields indicate the die revision and part revision numbers.
