STM32H742xI/G and STM32H743xI/G 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.

STM32H742xI/G and STM32H743xI/G devices are offered in 8 packages ranging from 100

pins to 240 pins/balls. The set of included peripherals changes with the device chosen.

These features make STM32H742xI/G and STM32H743xI/G 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.
