USB to STM32L451RET6 with FT231XS-R is there a schematic for this ?

SMilo.3 · ‎2022-10-11

I have the STM32L451RET6 and i would like to integrate it to my PCB. This PCB is directly connected to a PC over USB. So to communicate with the STM32 i need a FT231XS-R. So i am not sure how the schematic looks like.

I'd imagine the FS231XR-R has data sheets and perhaps reference manuals or designs.

At the STM32 level you'd likely be interfacing the USART RX / TX pins, at CMOS levels, and whatever flow control you deem necessary.

so you mean this schematic works ?

You don't need any FT2xx chip. You need to change L451 to L452 and use the built-in USB interface.

I can't this is the requirement
