STM32L476QEI6TR Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the STM32L476QEI6TR 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 STM32L476QEI6TR has 128 KB of RAM and 1 MB of Flash memory.
  • To use the DMA controller, configure the DMA channel to transfer data between peripherals and memory. Use the DMA request signals to trigger the transfer, and configure the DMA channel to use the correct data size and transfer mode.
  • The VBAT pin is used to supply power to the real-time clock (RTC) and backup registers when the main power supply is turned off. Connect a battery or a supercapacitor to the VBAT pin to maintain the RTC and backup registers during power-down mode.
