STM32F103. The peripherals that are missing in the microcontroller are specified

[AndreySmirnov81]

Peripherals that are not in the microcontroller and therefore should not be specified:

• Ethernet_MMC, Ethernet_MAC, Ethernet_PTP, Ethernet_DMA,
• OTG_FS_DEVICE, OTG_FS_GLOBAL, OTG_FS_HOST, OTG_FS_PWRCLK.

Low-density devices are STM32F101xx, STM32F102xx and STM32F103xx
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.
High-density devices are STM32F101xx and STM32F103xx 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 768 Kbytes and 1 Mbyte.
Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers.

Brief excerpt:

Ethernet (ETH): media access control (MAC) with DMA controller
applies only to STM32F107xx connectivity line devices.

USB on-the-go full-speed (OTG_FS)
applies only to STM32F105xx and STM32F107xx connectivity line devices.

And there is no mention of STM32f103 here.
