STM32L412RBT3 Frequently Asked Questions (FAQ)

  • The maximum clock frequency of the STM32L412RBT3 is 32 MHz, but it can be overclocked to 48 MHz using the internal PLL.

  • The internal voltage regulator (VREG) on the STM32L412RBT3 can be configured using the PWR_VREGx registers. The VREG can be set to 1.2V, 1.5V, or 1.8V, and can also be dynamically adjusted using the PWR_VREGxDYN register.

  • The maximum current consumption of the STM32L412RBT3 depends on the operating mode and clock frequency. In Run mode, the maximum current consumption is around 12 mA at 32 MHz, and in Low-power run mode, it is around 4 mA at 32 MHz.

  • The internal flash memory on the STM32L412RBT3 can be accessed using the FLASH registers. The flash memory is divided into sectors, and each sector can be erased and programmed using the FLASH_ERSECT and FLASH_PROG registers.

  • The BOOT0 and BOOT1 pins on the STM32L412RBT3 are used to select the boot mode of the device. BOOT0 selects between the internal flash memory and an external memory, while BOOT1 selects between the internal flash memory and the system memory.
