STM32G473MCT6 - STMicroelectronics

STM32G473MCT6 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be achieved with the internal oscillator?
  The internal oscillator (HSI) can be clocked up to 64 MHz, but the maximum frequency depends on the voltage range and temperature. Refer to the datasheet for specific values.
• How do I configure the clock tree to achieve the highest performance?
  Use the STM32CubeMX tool to generate the clock configuration code. It will help you to optimize the clock tree for your specific application.
• What is the maximum amount of RAM that can be used for DMA transfers?
  The STM32G473MCT6 has a total of 128 KB of SRAM, but only 64 KB is accessible by the DMA controller. The remaining 64 KB is reserved for the CPU.
• Can I use the USB OTG FS interface in device mode and host mode simultaneously?
  No, the USB OTG FS interface can only operate in one mode at a time. You need to switch between device mode and host mode using the OTG_FS_GNPTXSTS register.
• How do I implement a secure boot mechanism using the STM32G473MCT6?
  Use the STM32Trust security framework, which provides a secure boot mechanism using the ROM bootloader and the option bytes. Refer to the STM32Trust documentation for more information.
