Selecting the product temperature range
When ordering the microcontroller, the temperature range is specified in the order code (see
Figure 47: STM8A order codes on page 95
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 B version parts (-40 < T
Parts must be ordered at least with the temperature range suffix B.
