Universal serial bus device (USB)

The devices embed a USB controller with full-speed USB device compliant with the USB specification version 2.0.

The internal USB PHY supports USB FS signaling, embedded DP pull-up, and also battery charging detection

according to Battery Charging Specification Revision 1.2. The USB interface implements a full-speed (12 Mbit/s)

function interface with added support for USB 2.0 Link Power Management. It has software-configurable endpoint

setting with packet memory up to 1 Kbyte and suspend/resume support. It requires a precise 48 MHz clock that is

generated from the internal main PLL (the clock source must use an HSE crystal oscillator) or by the internal

48 MHz oscillator in automatic trimming mode. The synchronization for this oscillator can be taken from the USB

data stream itself (SOF signalization) which enables crystal less operation.

Debug support

3.31.1

Serial wire debug port (SW-DP)

An Arm® SW-DP interface is provided to allow a serial wire debugging tool to be connected to the MCU.
