Package characteristics
Using the values obtained in Table 70 T
STM32F103xC, STM32F103xD, STM32F103xE
is calculated as follows:
Jmax
–
T
For LQFP100, 46 °C/W
= 115 °C + (46 °C/W × 134 mW) = 115 °C + 6.2 °C = 121.2 °C
Jmax
This is within the range of the suffix 7 version parts (–40 < T < 125 °C).
J
In this case, parts must be ordered at least with the temperature range suffix 7 (see
Table 71: Ordering information scheme).
