Thermal characteristics

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.
