Selecting the product temperature range
When ordering the microcontroller, the temperature range is specified in the order code (see
Figure 48: Ordering information scheme on page
The following example shows how to calculate the temperature range needed for a given
application.
Assuming the following application conditions:
Maximum ambient temperature T
I
= 8 mA
DDmax
V
= 5 V
DD
maximum 20 I/Os used at the same time in output at low-level with I
V
= 0.4 V
OL
Equation 5
Equation 6
This gives:
P
= 400 mW and P
INTmax
Equation 7
Thus:
P
= 464 mW.
Dmax
Using the values obtained in
calculated as follows:
For LQFP64 46 °C/W
Equation 8
T
This is within the range of the suffix B version parts (-40 °C < T
Parts must be ordered at least with the temperature range suffix B.
Amax
P
= 8 mA x 5 V = 400 mW
INTmax
P
= 20 x 8 mA x 0.4 V = 64 mW
IOmax
64 mW:
IOmax
P
= 400 mW + 64 mW
Dmax
