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:

T
T
This is within the range of the suffix 6 version parts (-40 < T
must be ordered at least with the temperature range suffix 6.

I
Maximum 8 standard I/Os used at the same time in output at low level with I
V
Maximum 4 high sink I/Os used at the same time in output at low level with I
V
Maximum 2 true open drain I/Os used at the same time in output at low level with I

for LQFP32 can be calculated as follows, using the thermal resistance Θ
= 75° C + (59° C/W x 464 mW) = 75°C + 27°C = 102° C
= 2 V
= 1.5 V
= 82.5 mW + 360 mW
= 15 mA, V
= (10 mA x 2 V x 8 )+(20 mA x 2 V x 2)+(20 mA x 1.5 V x 4) = 360 mW
Dmax
= 15 mA x 5.5 V = 82.5 mW
