All STM32F10xxx in production include the bootloader detailed in this application note. The bootloader is used to program the application into the internal Flash memory. For more information about the Flash module organization, refer to the STM32F101xx and STM32F103xx Flash programming manual (PM0042). The specifications cover the architectural model of the bootloader for the STM32F10xxx family, but the low-level communication software supports all the microcontroller families that implement the bootloader.
