STM32F072CBY7TR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency of the STM32F072CBY7TR?
  The maximum clock frequency of the STM32F072CBY7TR is 48 MHz, which can be achieved using an external crystal oscillator or an internal high-speed internal oscillator (HSI).
• How do I configure the clock settings for the STM32F072CBY7TR?
  The clock settings for the STM32F072CBY7TR can be configured using the Clock Control Register (RCC) and the Power Control Register (PWR). The RCC register is used to select the clock source, while the PWR register is used to configure the voltage regulator and power modes.
• What is the purpose of the BOOT0 and BOOT1 pins on the STM32F072CBY7TR?
  The BOOT0 and BOOT1 pins on the STM32F072CBY7TR are used to select the boot mode of the device. BOOT0 is used to select between the internal flash memory and an external memory, while BOOT1 is used to select between the boot loader and the user application.
• How do I program the STM32F072CBY7TR using a serial wire debug (SWD) interface?
  The STM32F072CBY7TR can be programmed using a serial wire debug (SWD) interface using a debugger such as the ST-Link or a third-party debugger. The SWD interface is connected to the SWCLK and SWDIO pins on the device.
• What is the power consumption of the STM32F072CBY7TR in different power modes?
  The power consumption of the STM32F072CBY7TR varies depending on the power mode. In sleep mode, the power consumption is around 2.5 μA, while in stop mode, it is around 1.5 μA. In run mode, the power consumption is around 20 mA at 48 MHz.
