Selecting the product temperature range

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

Figure 50: STM8S005C6/K6 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= 82 °C (measured according to JESD51-2)



IDDmax = 15 mA, VDD = 5.5 V



Maximum eight standard I/Os used at the same time in output at low level with IOL = 10

mA, VOL= 2 V



Maximum four high sink I/Os used at the same time in output at low level with IOL = 20

mA, VOL= 1.5 V



Maximum two true open drain I/Os used at the same time in output at low level with



IOL = 20 mA, VOL= 2 V

PINTmax = 15 mA x 5.5 V = 82.5 mW

PIOmax = (10 mA x 2 V x 8 ) + (20 mA x 2 V x 2) + (20 mA x 1.5 V x 4) = 360 mW

This gives: PINTmax = 82.5 mW and PIOmax 360 mW:

PDmax = 82.5 mW + 360 mW

Thus: PDmax = 443 mW

Using the values obtained in Table 52: Thermal characteristics on page 91 TJmax is

calculated as follows for LQFP64 10 x 10 mm = 46 °C/W:

TJmax = 82 °C + (46 °C/W x 443 mW) = 82 °C + 20 °C = 102 °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.
