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/80-78830-1/topic/mechanical-information.html#fntarg_1_device-ordering-information) |

[^1^](https://docs.qualcomm.com/doc/80-78830-1/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.

RR = product revision code; BB = feature code that identifies an
ICβs 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/80-78830-1/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.
