Description STM32H750VB STM32H750IB STM32H750XB
14/201 DS12556 Rev 2
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
V
SS
. 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.
Figure 1 shows the general block diagram of the device family.
