STM32L476QGI3 Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the STM32L476QGI3 is 80 MHz, but it can be overclocked to 100 MHz with a reduced voltage supply.
  • To achieve the lowest power consumption, configure the clock tree to use the HSE (High-Speed External) clock source, and enable the PLL (Phase-Locked Loop) to generate the system clock. Additionally, disable any unused peripherals and clocks to reduce power consumption.
  • The VBAT pin is used to supply power to the real-time clock (RTC) and backup registers when the main power supply (VDD) is turned off. Connect a battery or a supercapacitor to the VBAT pin to maintain the RTC and backup registers during power-down modes.
  • The internal flash memory can be used to store data using the Flash Interface (FI) module. Use the HAL_FLASH_Write() function to write data to the flash memory, and the HAL_FLASH_Read() function to read data from the flash memory.
  • The maximum current that can be sourced or sunk by the GPIO pins is 20 mA. However, it's recommended to limit the current to 10 mA to ensure reliable operation and to prevent overheating.
