Selecting the product temperature range
When ordering the microcontroller, the temperature range is specified in the order code (see
Figure 49: STM8S207xx/208xx performance line ordering information scheme
page
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 for LQFP64 10 x 10 mm = 46 °C/W:
T
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.

Maximum ambient temperature T
I
Maximum eight standard I/Os used at the same time in output at low level with I
mA, V
Maximum four high sink I/Os used at the same time in output at low level with I
