1. The SPI1, SPI2 and SPI3 interfaces give the flexibility to work in an exclusive way in either the SPI mode or the I2S audio

mode.

2. The product junction temperature must be kept within the –40 to +105 °C range.

3. The product junction temperature must be kept within the –40 to +125 °C range.

4. Up to 300 MHz for STM32H755xxx3 sales types (extended industrial temperature range).

5. VDD/VDDA can drop down to 1.62 V by using an external power supervisor (see Section 3.5.2: Power supply supervisor) and

connecting PDR_ON pin to VSS. Otherwise the supply voltage must stay above 1.71 V with the embedded power voltage

detector enabled.

6. Using appropriate cooling methods to guarantee that the maximum junction temperature (125 °C) is not exceeded, the

maximum ambient temperature (85°C) can be exceeded.

7. The product junction temperature must be kept within the –40 to +140 °C range.

8. It is mandatory to use the SMPS step-down converter when the maximum junction temperature is higher than 125 °C.
