STM32L476RGT3 Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the STM32L476RGT3 is 80 MHz, but it can be overclocked to 100 MHz with some limitations.
  • The clock tree in the STM32L476RGT3 can be configured using the Clock Control Register (RCC) and the Power Control Register (PWR). You need to enable the High-Speed Internal Clock (HSI) or the External Clock (HSE) and then configure the clock prescalers to achieve the desired clock frequency.
  • The VBAT pin on the STM32L476RGT3 is used to connect a battery or a supercapacitor to store the backup registers and the real-time clock (RTC) when the device is powered off. This allows the device to retain its configuration and RTC information even when the main power is off.
  • The STM32L476RGT3 has several low-power modes, including Sleep, Stop, and Standby. These modes can be entered using the Power Down Mode (PDM) and the Wake-Up Interrupt (WKUP) registers. You need to configure the peripherals and the clock tree to achieve the desired power consumption.
  • The maximum amount of current that the STM32L476RGT3 can supply to an external device depends on the specific pin and the operating conditions. However, the maximum current that can be sourced or sunk by a GPIO pin is typically around 20-25 mA.
