Description

STM32H742xI/G and STM32H743xI/G devices are based on the high-performance Arm® Cortex®-M7 32-bit RISC core operating at up to 480 MHz. The Cortex® -M7 core features a floating point unit (FPU) which supports Arm® double-precision (IEEE 754 compliant) and single-precision data-processing instructions and data types. STM32H742xI/G and STM32H743xI/G devices support a full set of DSP instructions and a memory protection unit (MPU) to enhance application security.

STM32H742xI/G and STM32H743xI/G devices incorporate high-speed embedded memories with a dual-bank flash memory of up to 2 Mbytes, up to 1 Mbyte of RAM (including 192 Kbytes of TCM RAM, up to 864 Kbytes of user SRAM and 4 Kbytes of backup SRAM), as well as an extensive range of enhanced I/Os and peripherals connected to APB buses, AHB buses, 2x32-bit multi-AHB bus matrix and a multi layer AXI interconnect supporting internal and external memory access.

All the devices offer three ADCs, two DACs, two ultra-low power comparators, a low-power RTC, a high-resolution timer, 12 general-purpose 16-bit timers, two PWM timers for motor control, five low-power timers, a true random number generator (RNG). The devices support four digital filters for external sigma-delta modulators (DFSDM). They also feature standard and advanced communication interfaces.

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
