Selecting the product temperature range
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.
As applications do not commonly use the STM32F10xxx at maximum dissipation, it is useful
to calculate the exact power consumption and junction temperature to determine which
temperature range will be best suited to the application.
The following examples show how to calculate the temperature range needed for a given
application.
Example: high-performance application
Assuming the following application conditions:
Thus: P
Using the values obtained in
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 (see
Table 53: Ordering information
Example 2: High-temperature application
Using the same rules, it is possible to address applications that run at high ambient
temperatures with a low dissipation, as long as junction temperature T
specified range.
Assuming the following application conditions:
Thus: P
