Selecting the product temperature range
When ordering the microcontroller, the temperature range is specified in the order code (see
Figure 48: Ordering information scheme on page
The following example shows how to calculate the temperature range needed for a given
application.
Assuming the following application conditions:
Equation 5
Equation 6
This gives:
Equation 7
Thus:
Using the values obtained in
calculated as follows:
Equation 8
This is within the range of the suffix B version parts (-40 °C < T
Parts must be ordered at least with the temperature range suffix B.
