P-NUCLEO-USB001

P-NUCLEO-USB001 STM32 Nucleo pack for USB Type-C™ and Power Delivery Data brief Features • Two DRP USB Type-C™ receptacles • USB 2.0 FS data communication interface as peripheral • VBUS load and discharge switches • VCONN switches • Voltage and current sensing for VBUS monitoring • EMI filters • A power connector to interface with external power supply (not supplied) Description The STM32 Nucleo pack for USB Type-C™ and Power Delivery (P-NUCLEO-USB001) is a development tool for learning and developing solutions based on USB Type-C™ and USB Power Delivery technologies. This tool, in association with the certified embedded software solution (X-CUBE-USB-PD), provides the means to control two USB Type-C™ ports using a single STM32F072 32-bit microcontroller, based on ARM® Cortex®-M0. The X-CUBE-USB-PD is compliant with the USB Type-C 1.2 and USB Power Delivery 2.0 specifications. A simple analog front-end PHY is used to interface the STM32F072 MCU with the Configuration Channels (CC lines) of the Type-C receptacles and to allow the communication over these lines using the Power Delivery communication protocol. 1. Picture is not contractual. The P-NUCLEO-USB001 is fully configurable and ready to support different configurations such as Provider, Consumer or DRP. X-CUBE-USB-PD is compliant with the USB Type-C™ 1.2 and the Power Delivery 2.0 specifications.
