Example 2: High-temperature application

Using the same rules, it is possible to address applications that run at high ambient

temperatures with a low dissipation, as long as junction temperature TJ remains within the

specified range.

Assuming the following application conditions:

Maximum ambient temperature TAmax = 115 °C (measured according to JESD51-2),

IDDmax = 20 mA, VDD = 3.5 V, maximum 9 I/Os used at the same time in output at low

level with IOL = 8 mA, VOL= 0.4 V

PINTmax = 20 mA × 3.5 V= 70 mW

PIOmax = 9 × 8 mA × 0.4 V = 28.8 mW

This gives: PINTmax = 70 mW and PIOmax = 28.8 mW:

PDmax = 70 + 28.8 = 98.8 mW

Thus: PDmax = 98.8 mW

Using the values obtained in Table 86 TJmax is calculated as follows:

– For LQFP100, 41°C/W

TJmax = 115 °C + (41°C/W × 98.8 mW) = 115 °C + 4.05 °C = 119.05 °C

This is within the range of the suffix 7 version parts (–40 < TJ < 125 °C).

In this case, parts must be ordered at least with the temperature range suffix 7 (see

Section 8: Ordering information).
