Hi

Pullup resistors required for device mode (actually for this mcu not required)

Pullups and pulldowns are internal in this MCU and handled automatically depending from the mode USB periph configured.

EMI and ESD protection recommended.

Thank you very much

Hello @nguen nguyen​ ,

For USB FS downstream application, it's required to use a switch with over-current protection (indication to the user in case of a VBUS overload ) and esd protection (to be placed as close as possible to the USB connector).

For more details, you may refer to the application note AN4879 "USB hardware and PCB guidelines using STM32 MCUs". It provides hardware guidelines for PCB design.

@nguen nguyen​ ,

Just for your information, I have renamed your request with a more precise title and have added the description you have provided in the "Details" area.

This will make the post clearer.
