Evaluating the maximum junction temperature for an application
When ordering the microcontroller, the temperature range is specified in the ordering
information scheme shown in Table 51: Ordering information scheme.
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:
Maximum ambient temperature TAmax = 82 °C (measured according to JESD51-2),
IDDmax = 50 mA, VDD = 3.5 V, maximum 20 I/Os used at the same time in output at low
level with IOL = 8 mA, VOL= 0.4 V and maximum 8 I/Os used at the same time in output
mode at low level with IOL = 20 mA, VOL= 1.3 V
PINTmax = 50 mA × 3.5 V= 175 mW
PIOmax = 20 × 8 mA × 0.4 V + 8 × 20 mA × 1.3 V = 272 mW
This gives: PINTmax = 175 mW and PIOmax = 272 mW
PDmax = 175 + 272 = 447 mW
Thus: PDmax = 447 mW
–
For LQFP64, 45 °C/W
TJmax = 82 °C + (45 °C/W × 447 mW) = 82 °C + 20.1 °C = 102.1 °C
This is within the junction temperature range of the STM32F101xx (–40 < TJ < 105 °C).
