A.2 Part Markings
Tiva™ C Series microcontrollers are marked with an identifying number, as shown in the figure
below.
This identifying number contains the following information:
Lines 1 and 5: Internal tracking numbers
Lines 2 and 3: Part number
For example, TM4C123G on the second line followed by E6PZI on the third line indicates orderable
part number TM4C123GE6PZI. 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. Pre-production parts also include a revision
number in the part number, for example, XM4C123G followed by E6PZI5 indicates revision 5.
Production parts do not include a revision number in the part number. Some devices also include
an internal code after the temperature character field. The DID0 register identifies the version
of the microcontroller. The MAJOR and MINOR bit fields indicate the die revision number. Combined,
the MAJOR and MINOR bit fields indicate the TM4C129x microcontroller part revision number.

Line 4: Date code
The first two characters on the fourth line indicate the date code, followed by internal tracking
numbers. The two-digit date code YM indicates the last digit of the year, then the month. For
example, a 34 for the first two digits of the fourth line indicates a date code of April 2013.
