Selecting the product temperature range
When ordering the microcontroller, the temperature range is specified in the order code (see
Section 12: Ordering information
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:
This is within the range of the suffix B version parts (-40 < T
Parts must be ordered at least with the temperature range suffix B.
