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:
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
PINTmax = 8 mA x 5 V= 400 mW
PIOmax = 20 x 8 mA x 0.4V = 64 mW
This gives: PINTmax= 400 mW and PIOmax 64 mW:
PDmax = 400 mW + 64 mW
Thus: PDmax = 464 mW
–
For LQFP100, 46°C/W
TJmax = 82° C + (46° C/W x 464 mW) = 82°C + 21°C = 103° C
This is within the range of the suffix 6 version parts (-40 < TJ < 105° C).
In this case, parts must be ordered at least with the temperature range suffix 6
–
For BGA64, 58°C/W
TJmax = 82° C + (58° C/W x 464 mW) = 82°C + 27°C = 109° C
This is within the range of the suffix 7 version parts (-40 < TJ < 125° C).
In this case, parts must be ordered at least with the temperature range suffix 7
