18 / 337 page  Description STM32H750VB STM32H750ZB STM32H750IB STM32H750XB 18/336 DS12556 Rev 6 STM32H750xB devices operate in the –40 to +85 °C temperature range from a 1.62 to 3.6 V power supply. The supply voltage can drop down to 1.62 V by using an external power supervisor (see Section 3.5.2: Power supply supervisor) and connecting the PDR_ON pin to VSS. Otherwise the supply voltage must stay above 1.71 V with the embedded power voltage detector enabled. Dedicated supply inputs for USB (OTG_FS and OTG_HS) are available on all packages except LQFP100 to allow a greater power supply choice. A comprehensive set of power-saving modes allows the design of low-power applications. STM32H750xB devices are offered in 3 packages ranging from 100 pins to 240 pins/balls. The set of included peripherals changes with the device chosen. These features make STM32H750xB microcontrollers suitable for a wide range of applications: • Motor drive and application control • Medical equipment • Industrial applications: PLC, inverters, circuit breakers • Printers, and scanners • Alarm systems, video intercom, and HVAC • Home audio appliances • Mobile applications, Internet of Things • Wearable devices: smart watches.
