STM32F100CBT7B Frequently Asked Questions (FAQ)

  • The maximum clock frequency of the STM32F100CBT7B is 24 MHz, but it can be overclocked to 36 MHz with a reduced voltage supply.

  • The clock settings for the STM32F100CBT7B can be configured using the Clock Control Register (RCC_CR) and the Flash Control Register (FLASH_ACR). You can also use the STM32CubeMX tool to generate the clock configuration code.

  • The BOOT0 and BOOT1 pins are used to select the boot mode of the microcontroller. BOOT0 is used to select between the internal flash and the system memory, while BOOT1 is used to select between the internal flash and an external memory.

  • The USART peripheral on the STM32F100CBT7B can be used for asynchronous communication. You need to configure the USART clock, enable the USART peripheral, and set the baud rate, data bits, stop bits, and parity. You can use the HAL library or write your own driver to use the USART peripheral.

  • The power consumption of the STM32F100CBT7B depends on the operating frequency, voltage supply, and peripherals used. In sleep mode, the power consumption is around 2.5 mA, while in run mode, it can be up to 350 mA.
