STM32L073CBT6 - STMicroelectronics

STM32L073CBT6 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency of the STM32L073CBT6?
  The maximum clock frequency of the STM32L073CBT6 is 32 MHz, but it can be overclocked to 48 MHz with a reduced voltage range.
• How do I configure the internal oscillator (HSI) on the STM32L073CBT6?
  The internal oscillator (HSI) on the STM32L073CBT6 can be configured using the RCC_ICSCR register. The HSI is enabled by setting the HSION bit in the RCC_ICSCR register, and the frequency can be trimmed using the HSITRIM bits.
• What is the power consumption of the STM32L073CBT6 in low-power modes?
  The power consumption of the STM32L073CBT6 in low-power modes depends on the specific mode and configuration. In Stop mode, the current consumption is typically around 2.5 μA/MHz, while in Standby mode, it is around 1.5 μA. In Shutdown mode, the current consumption is typically around 1 μA.
• How do I use the DMA controller on the STM32L073CBT6?
  The DMA controller on the STM32L073CBT6 can be used to transfer data between peripherals and memory. The DMA controller is configured using the DMA_CCRx registers, and the transfer is triggered by setting the DMA_EN bit in the DMA_CCRx register.
• What is the maximum amount of flash memory that can be used for user data on the STM32L073CBT6?
  The STM32L073CBT6 has 192 KB of flash memory, but some of this memory is reserved for the bootloader and other system functions. The maximum amount of flash memory available for user data is around 128 KB.
