Selecting the product temperature range
When ordering the microcontroller, the temperature range is specified in the order codes
(see
The following example shows how to calculate the temperature range needed for a given
application.
Assuming the following application conditions:
Using the values obtained in
calculated as follows:
Maximum ambient temperature T
I
level with I
This gives: P
Thus: P

For LQFP64 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 B
