Selecting the product temperature range
When ordering the microcontroller, the temperature range is specified in the order code
Table 49: Order codes on page
The following example shows how to calculate the temperature range needed for a given
application.
Assuming the following application conditions:

For LQFP100, 46°C/W
This is within the range of the suffix 6 version parts (-40 < T
In this case, parts must be ordered at least with the temperature range suffix 6
(see
For BGA64, 58°C/W
This is within the range of the suffix 7 version parts (-40 < T
In this case, parts must be ordered at least with the temperature range suffix 7
