Selecting the product temperature range

When ordering the microcontroller, the temperature range is specified in the order code (see

Figure 53: STM8S003F3/K3 value line ordering information scheme(1)).

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 = 5.0 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 5.0 V = 400 mW

PDmax = 400 mW + 64 mW

Thus: PDmax = 464 mW

Using the values obtained in Section Table 55.: Thermal characteristics TJmax is calculated

as follows for LQFP32 7 x 7 mm = 60 °C/W:

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.
