STM32L451CCU3TR Frequently Asked Questions (FAQ)
-
The maximum operating temperature range for the STM32L451CCU3TR is -40°C to 125°C, but it can be extended to 150°C with some limitations on the clock frequency and supply voltage.
-
The internal clock source for the STM32L451CCU3TR can be configured using the Clock Control Register (RCC_CR) and the Clock Configuration Register (RCC_CFGR). The internal clock source can be set to HSI (High-Speed Internal), MSI (Multi-Speed Internal), or HSE (High-Speed External) clock sources.
-
The maximum current consumption of the STM32L451CCU3TR depends on the operating mode and clock frequency. In Run mode, the maximum current consumption is around 350 μA/MHz at 3.3 V and 25°C. In Low Power Run mode, the maximum current consumption is around 150 μA/MHz at 3.3 V and 25°C.
-
The DMA controller on the STM32L451CCU3TR can be used to transfer data between peripherals and memory without CPU intervention. The DMA controller is configured using the DMA_SxCR (DMA stream x configuration register) and DMA_SxNDTR (DMA stream x number of data register). The DMA controller can be triggered by peripheral requests or by software.
-
The BOOT0 and BOOT1 pins on the STM32L451CCU3TR are used to select the boot mode of the device. BOOT0 and BOOT1 pins can be used to select between the internal flash memory, system memory, or external memory as the boot source.
