STM32L452REI6 Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the STM32L452REI6 is 32 MHz, but it can be overclocked to 48 MHz with a reduced voltage range.
  • The internal oscillator (HSI) on the STM32L452REI6 can be configured using the RCC_HSICFGR register. Set the HSITRIM bits to adjust the oscillator frequency, and the HSICAL bits to adjust the oscillator calibration.
  • The maximum current consumption of the STM32L452REI6 depends on the operating mode and frequency. In Run mode, the maximum current consumption is around 350 mA at 32 MHz, and in Low Power Run mode, it is around 150 mA at 32 MHz.
  • The DMA controller on the STM32L452REI6 can be used to transfer data between peripherals and memory. Configure the DMA channel, set the transfer mode, and enable the DMA interrupt to use the DMA controller.
  • The VBAT pin on the STM32L452REI6 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.
