Thermal characteristics

The maximum chip junction temperature (TJ max) must never exceed the values given in

Table 18: General operating conditions.

The maximum chip-junction temperature, TJ max, in degrees Celsius, may be calculated

using the following equation:

TJ max = TA max + (PD max x JA)

Where:

 TA max is the maximum ambient temperature in °C,

 JA is the package junction-to-ambient thermal resistance, in C/W,

 PD max is the sum of PINT max and PI/O max (PD max = PINT max + PI/Omax),

 PINT max is the product of IDD and VDD, expressed in Watts. This is the maximum chip

internal power.

PI/O max represents the maximum power dissipation on output pins where:

PI/O max = (VOL × IOL) + ((VDD – VOH) × IOH),

taking into account the actual VOL / IOL and VOH / IOH of the I/Os at low and high level in the

application.

Selecting the product temperature range

When ordering the microcontroller, the temperature range is specified in the ordering

information scheme shown in Section 8: Part numbering.

Each temperature range suffix corresponds to a specific guaranteed ambient temperature at

maximum dissipation and, to a specific maximum junction temperature.

As applications do not commonly use the STM32F0xx at maximum dissipation, it is useful to

calculate the exact power consumption and junction temperature to determine which

temperature range will be best suited to the application.

The following examples show how to calculate the temperature range needed for a given

application.
