17 / 251 page ![]() DS12931 Rev 1 17/251 STM32H757xI Description 55 DFSDM Yes Maximum CPU frequency 480 MHz Operating voltage 1.62 to 3.6 V(2) Operating temperatures Ambient temperatures: –40 up to +85 °C(3) Junction temperature: –40 to + 125 °C Package WLCSP156 UFBGA169 LQFP176 LQFP208 TFBGA240+ 25 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. 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. 3. The product junction temperature must be kept within the –40 to +125 °C range. Table 2.
