12.1
JESD51-2 integrated circuits thermal test method environment conditions - natural convection
(still air). Available from www.jedec.org.
Selecting the product temperature range
12.2
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= 75 °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
Amax
• PDmax = 400 mW + 64 mW
Thus: PDmax = 464 mW
TJmax for LQFP32 can be calculated as follows, using the thermal resistance ΘJA:
TJmax = 75 °C + (60 °C/W x 464 mW) = 75 °C + 27.8 °C = 102.8 °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.
