Product details

     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 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.

      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
