STM32G473VCT3 - STMicroelectronics

STM32G473VCT3 Frequently Asked Questions (FAQs)

• What is the maximum frequency of the internal oscillator?
  The internal oscillator (HSI) can operate up to 64 MHz, but the maximum frequency depends on the specific application and the tolerance of the oscillator. Typically, it is recommended to use a frequency of 16 MHz or 32 MHz for most applications.
• How do I configure the clock tree?
  The clock tree configuration involves setting the clock sources, prescalers, and clock dividers. The STM32CubeMX tool can be used to generate the clock configuration code. Alternatively, the STM32G473VCT3 datasheet and the AN4760 application note provide detailed information on clock tree configuration.
• What is the maximum current consumption of the microcontroller?
  The maximum current consumption of the STM32G473VCT3 depends on the operating frequency, voltage, and peripherals used. According to the datasheet, the typical current consumption is around 350 mA at 180 MHz with all peripherals enabled. However, this value can vary depending on the specific application.
• How do I use the DMA controller?
  The DMA (Direct Memory Access) controller is used to transfer data between peripherals and memory without CPU intervention. The STM32G473VCT3 has two DMA controllers, DMA1 and DMA2. The DMA controller can be configured using the STM32CubeMX tool or by writing custom code using the STM32G473VCT3 datasheet and the RM0444 reference manual.
• What is the purpose of the BOOT0 and BOOT1 pins?
  The BOOT0 and BOOT1 pins are used to select the boot mode of the microcontroller. BOOT0 selects the boot mode (main flash, system memory, or serial boot), while BOOT1 selects the boot device (flash, SRAM, or external memory). The boot mode is configured by setting the BOOT0 and BOOT1 pins high or low during reset.
