STM32 USB FS Core and USB OTG Core are two different USB cores available in STM32 microcontrollers.
The USB FS (Full-Speed) core is a simpler version of the USB OTG (On-The-Go) core and is designed for devices that only need to operate as a USB device, such as a USB flash drive or a USB keyboard. The USB FS core supports USB 1.1 and USB 2.0 Full-Speed (12 Mbps) communication.
On the other hand, the USB OTG core is a more advanced USB core and is designed for devices that need to operate in both USB host and device modes, such as a smartphone or a tablet. The USB OTG core supports USB 1.1, USB 2.0 Full-Speed (12 Mbps), and USB 2.0 High-Speed (480 Mbps) communication.
Both cores are available in STM32 microcontrollers and can be used depending on the requirements of the USB device application.
