## Device ordering information

The short description is used to order QTI products, and is present on both the customer
label and in this document. The short description includes the product name,
configuration code, package type, product revision code, source code, and feature
code/program ID of the part.
This device can be ordered using the identification code as shown in the following
table:
| Device ID code | AAA-AAAA | -P | -TTTTTT | A | -RR | -S | -BB or -PID[^1^](https://docs.qualcomm.com/doc/80-78832-1/topic/mechanical-information.html#fntarg_1_device-ordering-information) |
| --- | --- | --- | --- | --- | --- | --- | --- |
| Symbol definition | Product name | Configuration code | Package type | Package variable | Product revision | Source code | Feature code |
| Example | QCC-748M | -2 | -LGM52 | -MT | -01 | -0 | -AA |
| Example | QCC-748M | -2 | -LGM52 | -TR | -01 | -0 | -AA |
| Example | QCC-748M | -2 | -LGM52A | -MT | -01 | -0 | -AB |
| Example | QCC-748M | -2 | -LGM52A | -TR | -01 | -0 | -AB |

[^1^](https://docs.qualcomm.com/doc/80-78832-1/topic/mechanical-information.html#fnsrc_1_device-ordering-information) The
feature code (BB) and the program ID (PID) are mutually exclusive. A
product may have one of them or none of them, but it will never have
both. If there is no feature code/program ID, this field is blank,
and the short description ends after the source configuration code
(S).
Note:
The shipping package is either TR (tape and reel) or MT (matrix tray).
For availability and information to order QTI products, contact the Qualcomm sales
team.

[^2^](https://docs.qualcomm.com/doc/80-78832-1/topic/mechanical-information.html#fnsrc_2_device-ordering-information) P =
product configuration code; RR = product revision code; BB = feature
code that identifies an IC’s specific feature set, which
distinguishes it from other versions or variants. Feature sets are
detailed in the comments column.
[^3^](https://docs.qualcomm.com/doc/80-78832-1/topic/mechanical-information.html#fnsrc_3_device-ordering-information) S is the source configuration code that identifies all of the
qualified die fabrication-source combinations available when the
particular sample type was shipped.
