3 CRC calculation unit Medium-density devices are STM32F101xx and STM32F103xx microcontrollers wherethe Flash memory density ranges between 32 and 128 Kbytes.
High-density devices are STM32F101xx and STM32F103xx microcontrollers where theFlash memory density ranges between 256 and 512 Kbytes.
This Section applies to the whole STM32F10xxx family, unless otherwise specified.
