STM32L451CCU3 Frequently Asked Questions (FAQ)

  • The maximum clock frequency of the STM32L451CCU3 is 32 MHz, but it can be overclocked to 64 MHz using the internal PLL.

  • The clock settings can be configured using the Clock Control Register (RCC_CR) and the Clock Configuration Register (RCC_CFGR). The RCC_CR register is used to enable and disable the clock sources, while the RCC_CFGR register is used to select the clock source and configure the clock prescalers.

  • The VBAT pin is used to connect a battery or a supercapacitor to the microcontroller. It is used to power the real-time clock (RTC) and the backup registers when the main power supply is turned off.

  • The STM32L451CCU3 has several low-power modes, including Sleep, Stop, and Standby modes. These modes can be entered using the Power Management Unit (PMU) and the Cortex-M4 processor's sleep modes. The PMU is used to control the power modes, while the Cortex-M4 processor's sleep modes are used to reduce power consumption.

  • The maximum amount of current that the STM32L451CCU3 can supply to an external device is 20 mA per GPIO pin, with a total current limit of 100 mA for all GPIO pins combined.
