Ordering Information
The figure below defines the full set of potential orderable part numbers for all the Stellaris^® LM3S
microcontrollers. See the Package Option Addendum for the valid orderable part numbers for the
LM3S5G31 microcontroller.
LM3Snnnn–gppss–rrm
Part Number
nnn = Sandstorm-class parts
nnnn = All other Stellaris® parts
Temperature
E = –40°C to +105°C
I = –40°C to +85°C
Package
BZ = 108-ball BGA
QC = 100-pin LQFP
QN = 48-pin LQFP
QR = 64-pin LQFP
Shipping Medium
T = Tape-and-reel
Omitted = Default shipping (tray or tube)
Revision
Speed
20 = 20 MHz
25 = 25 MHz
50 = 50 MHz

Part Markings
The Stellaris microcontrollers are marked with an identifying number. This code contains the following
information:
■ The first line indicates the part number, for example, LM3S9B90.
■ In the second line, the first eight characters indicate the temperature, package, speed, revision,
and product status. For example in the figure below, IQC80C0X indicates an Industrial temperature
(I), 100-pin LQFP package (QC), 80-MHz (80), revision C0 (C0) device. The letter immediately
following the revision indicates product status. An X indicates experimental and requires a waiver;
an S indicates the part is fully qualified and released to production.
■ The remaining characters contain internal tracking numbers.
