Hello @ssunlove 

The link you're mentioning: Concurrent use of USB and CAN with STM32F103

Unfortunately no, the USB and CAN can be used in the same application but not at the same time on all the STM32F1 series, including the STM32F105R8T6.

Yes, you can check this information by looking at the memory mapping in your product datasheet 

For STM32F1 series: There is a shared 512-byte SRAM between USB and CAN

For STM32F2 series: it has separate USB and CAN peripherals
