STM32F070CB/RB/C6/F6

Functional overview

3.16

Universal serial bus (USB)

The STM32F070CB/RB/C6/F6 embeds a full-speed USB device peripheral 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 KB and suspend/resume support.

It requires a precise 48 MHz clock which can be generated from the internal main PLL (the

clock source must use an HSE crystal oscillator).

3.17

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.
