Evaluating the maximum junction temperature for an application
When ordering the microcontroller, the temperature range is specified in the ordering
information scheme shown in
Each temperature range suffix corresponds to a specific guaranteed ambient temperature at
maximum dissipation and, to a specific maximum junction temperature. Here, only
temperature range 6 is available (–40 to 85 °C).
The following example shows how to calculate the temperature range needed for a given
application, making it possible to check whether the required temperature range is
compatible with the STM32F101xx junction temperature range.
Example: high-performance application
Assuming the following application conditions:
Thus: P
Using the values obtained in
This is within the junction temperature range of the STM32F101xx (–40 < T

= 20 × 8 mA × 0.4 V + 8 × 20 mA × 1.3 V = 272 mW
= 447 mW
