The STM32H743VIT6 supports multiple low-power modes and has a fast wake-up feature. In low-power mode, the chip can go to sleep but still keep important functions running so that it can wake up quickly when necessary. This feature allows it to have a long lifetime in battery-powered devices.



Ⅳ. How to use STM32H743VIT6?


1. Power management: STM32H743VIT6 is a high-performance microcontroller based on the ARM Cortex-M7 core produced by STMicroelectronics. Its power supply voltage range is 1.8V to 3.6V. During use, in order to ensure that STM32H743VIT6 can operate stably and reliably, we need to provide it with a suitable and stable power supply.


2. Peripheral configuration: STM32H743VIT6 provides a variety of peripheral interfaces, we need to select the appropriate interface for configuration and use according to specific application scenarios. If the application involves communication between distributed control systems, then CAN bus will be an ideal choice; if the system needs to exchange data with personal computers or other USB devices, then we can choose the built-in USB interface; and if the system needs to realize high-speed data transfer with other devices, then we can choose high-speed UART or SPI interface.


3. Select development environment: STM32H743VIT6 can use Keil MDK, IAR Embedded Workbench and other integrated development environments (IDEs), or we can use the STM32CubeMX tools provided by ST official for rapid configuration and development.

Ⅵ. Low-power strategy of STM32H743VIT6


There are several ways to reduce power consumption on STM32H743VIT6.

1. Save power consumption when the CPU is idle, by selecting among the available low-power mode according to the user application needs. This allows achieving the best compromise between short startup time, low-power consumption, as well as available wakeup sources.

2. Decrease the dynamic power consumption by slowing down the system clocks even in Run mode and by individually clock gating the peripherals that are not used.


The devices feature several low-power modes:

• Standby (System powered down)

• Stop (System clock stopped)

• CSleep (CPU clock stopped)

• CStop (CPU sub-system clock stopped)

• DStandby (Domain powered down)

• DStop (Domain bus matrix clock stopped)


CSleep and CStop low-power modes are entered by the MCU when executing the WFI (Wait for Interrupt) or WFE (Wait for Event) instructions, or when the SLEEPONEXIT bit of the Cortex®-Mx core is set after returning from an interrupt service A domain can enter low-power mode (DStop or DStandby) when the processor, its subsystem and the peripherals allocated in the domain enter low-power mode. If part of the domain is not in low-power mode, the domain remains in the current mode. Finally the system can enter Stop or Standby when all EXTI wakeup sources are cleared and the power domains are in DStop or DStandby mode.



Ⅶ. Market situation of STM32H743VIT6

The above figure shows the price, market popularity and inventory trends of STM32H743VIT6. Through analysis, we can draw the following conclusions:

1. Price changes and search volume converge, with a rebound during the period.

2. Search volume has dropped significantly from its July high.

3. Inventory volume in March and July corresponds to the high point of search volume, and has increased significantly in October. Inventory volume and search volume are inversely related to price movement.


From the chart, we can clearly observe that the price peaks of STM32H743VIT6 were all concentrated in July, which indicates that the market demand for this material reached its highest peak during the year at that time. Obviously, when the third quarter begins, the market has high expectations for the recovery of traditional electronic products in the peak season. However, it is worth noting that the price of STM32H743VIT6 once climbed to a high of more than 700 yuan in 2022. In comparison, the price high point shown in 2023 is actually the level after a sharp price reduction. This recovery is more like a short-term "return to light." In addition, the popularity of the "Double Eleven" shopping festival in 2023 is mediocre, which further proves that the peak season recovery effect is quite limited, and naturally cannot provide strong support for the rise in material prices.
