Hello.

As it is in description the main diffrences in STM32F familly are on-board flash and ram. So if you are using STM32F107VC you can use F103VC variant. 

Between STM32F107VC and STM32103VD the main diffrences are in their periphelias:
3xSPI;2xI2S;2xI2C;3xUSART;2xUART;SDIO;USB;CAN                                                           STM32103
3xSPI;2xI2S;2xI2C;3xUSART;2xUART;USB OTG FS;2xCAN;Ethernet MAC10/100;one add timer     STM32107

As you can see here the drivers only you will have to support are for periphelias which are missing in 103. 

Best regards
Qber
