Selecting the product temperature range
When ordering the microcontroller, the temperature range is specified in the order code (see
The following example shows how to calculate the temperature range needed for a given
application.
Assuming the following application conditions:
Maximum ambient temperature TAmax = 82 °C (measured according to JESD51-2)
–IDDmax = 8 mA
–VDD = 5 V
maximum 20 I/Os used at the same time in output at low-level with IOL = 8 mA
–VOL = 0.4 V
Equation 5
PINTmax = 8 mA x 5 V = 400 mW
Equation 6
PIOmax = 20 x 8 mA x 0.4 V = 64 mW
This gives:
PINTmax = 400 mW and PIOmax 64 mW:
Equation 7
PDmax = 400 mW + 64 mW
Thus:
PDmax = 464 mW.
Using the values obtained in Table 62: Thermal characteristics on page 95 TJmax is
calculated as follows:
For LQFP64 46 °C/W
Equation 8
Tjmax = 82 °C + (46 °C/W x 464 mW) = 82 °C + 21 °C = 103 ° C
This is within the range of the suffix B version parts (-40 °C < Tj < 105 ° C).
Parts must be ordered at least with the temperature range suffix B.
