Selecting the product temperature range
When ordering the microcontroller, the temperature range is specified in the order code.
The following example shows how to calculate the temperature range needed for a given
application.
Assuming the following application conditions:
•
•
•
•
T
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.

for LQFP32 can be calculated as follows, using the thermal resistance Θ
= 75 °C + (60 °C/W x 464 mW) = 75 °C + 27.8 °C = 102.8 °C
= 8 mA, V
