Posted on May 18, 2017 at 07:51Here ST's explanation from their
stm32f10x.h
file (guess it causes the post to go into moderation, too):
/* ♯ define STM32F10X_LD */ /*!< STM32F10X_LD: STM32 Low density devices */

/* Tip: To avoid modifying this file each time you need to switch between these
devices, you can define the device in your toolchain compiler preprocessor.
- Low-density devices are STM32F101xx, STM32F102xx and STM32F103xx microcontrollers
where the Flash memory density ranges between 16 and 32 Kbytes.
- Low-density value line devices are STM32F100xx microcontrollers where the Flash
memory density ranges between 16 and 32 Kbytes.
- Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx microcontrollers
where the Flash memory density ranges between 64 and 128 Kbytes.
- Medium-density value line devices are STM32F100xx microcontrollers where the
Flash memory density ranges between 64 and 128 Kbytes.
- High-density devices are STM32F101xx and STM32F103xx microcontrollers where
the Flash memory density ranges between 256 and 512 Kbytes.
- High-density value line devices are STM32F100xx microcontrollers where the
Flash memory density ranges between 256 and 512 Kbytes.
- XL-density devices are STM32F101xx and STM32F103xx microcontrollers where
the Flash memory density ranges between 512 and 1024 Kbytes.
- Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers.
