STM32F37xxx Package characteristics
126
Using the values obtained in Table 80 T
Jmax
is calculated as follows:
– For LQFP100, 46°C/W
T
Jmax
= 115 °C + (46°C/W × 98.8 mW) = 115 °C + 4.54 °C = 119.5 °C
This is within the range of the suffix 7 version parts (–40 < T
J
< 125 °C).
In this case, parts must be ordered at least with the temperature range suffix 7 (see
Section 8: Part numbering).
