STM32 Nucleo pack for USB Type-C™ and Power Delivery with the Nucleo-F072RB board and the STUSB1602

Introduction The USB Type-C™ and Power Delivery Nucleo pack P-NUCLEO-USB002 includes:

the NUCLEO-F072RB board

the P-NUCLEO-USB002 expansion board based on the certified STUSB1602 USB Type-C portcontroller with PD PHY and BMC driver

a full-featured Type-C cable

These components, together with the X-CUBE-USB-PD certified STM32F0 USB Type-C PD middleware stack, form a platform for demonstrating USB Type-C and USB Power Delivery (USB PD) capabilities and facilitating solution development.

The new USB PD protocol expands USB functionality by providing up to 100 W power over the same cable used for data communication. Devices supporting the protocol are able to negotiate voltage and current over the USB power pins and define their roles as Provider or Consumer accordingly.

Once the platform is configured, the embedded demonstration firmware can signal cable status (attached or detached) and orientation information, as well as the role of each of the two ports.

1 USB Type-C and Power Delivery

1.1 Overview

The USB Type-C™ and Power Delivery technologies simplify development and enhance user experience; the new reversible USB Type-C connector insertion is more intelligent and user friendly.

These technologies offer a smart connector able to carry all the necessary data (including video) as well as negotiate up to 100 W supply or charge connected equipment according to the Power Delivery protocol.

Less cables, less connectors and universal chargers are among the final objectives.

The USB Type-C connector supports up to 15 W (5 V at 3 A), which rises to 100 W (up to 20 V at 5 A) adopting the USB Power Delivery feature.

1.2 Main characteristics

The USB Implementer Forum (USB-IF) introduces these complementary specifications:

1. the USB Type-C™ receptacle, plug and cable specification rev. 1.2 2. the USB Power Delivery (PD) specification rev. 2.0 that allows two PD compliant

entities to exchange up to 100 W during their negotiations.

Any system embedding a USB Type-C receptacle or plug which is designed to implement a USB Power Delivery application such as a single port device, a multi-port hub or a simple cable is based on these specifications.

The connector is intended for a wide range of charging applications like computers, displays and mobile phones, with all the advanced features of PD:

power role negotiation

power sourcing and consumption level negotiation

electronically marked cable identification

vendor-specific message exchange

alternate-mode negotiation, allowing different communication protocols to be routed onto the reconfigurable pins of the USB Type-C connectors.

The cables use the same male connector on both ends.

UM2191 USB Type-C and Power Delivery

DocID030479 Rev 2 7/55

Figure 2: USB plug form factors

The new USB Type-C covers all the features provided by the previous generation USB plugs in a single connector, rendering USB usage easier and more flexible. It supports all protocols from USB2.0 onward, including power capability.

The USB Type-C connection allows ports to operate in host-mode only, device-mode only or dual-role. Both data and power roles can be independently and dynamically swapped using the USB PD protocol.

1.3 USB Type-C™ pin map

USB Type-C™ plugs and receptacles are 24-pin connectors with two groups of pin connections arranged so as to ensure pinout reversibility for any connection.

The symmetrical connections: are

eight power pins: VBUS/GND

USB2.0 differential pairs (D+/D-)

The asymmetrical connections are:

two sets of Tx/Rx signal paths supporting USB3.1 data rates

two configuration channels (CC lines) for the discovery, configuration and management of USB Type-C power delivery features

two sideband use (SBU lines) signals for analog audio modes; may be used by alternate mode.

1.4 Port configurations

As stated in the USB Type-C™ and USB Power Delivery specifications, a data role (host or device) and a power role (source, sink or DRP) can be assigned to each port. Both data and power roles can be independently and dynamically swapped according to rules and procedures established by the specifications.

1.4.1 Downstream Facing Port (DFP)

The downstream facing port is associated with the flow of data in a USB connection. It is usually the port on a host or hub which devices connect to.

In its initial state, the DFP must be able to supply VBUS and VCONN and support data.

1.4.2 Upstream Facing Port (UFP)

The upstream facing port is associated with the data flow in a USB connection. It represents the port on a device or a hub that connects to a host or the DFP of a hub. In its initial state, UFP sinks VBUS and supports data (e.g., display).

1.4.3 Source or provider

This port must source power over VBUS (5 V to 20 V and up to 5 A), and most commonly belongs to a host or hub DFP. A provider must assert an Rp resistor (pull-up resistor, See Figure 5: "USB power delivery architecture") on CC pins (configuration channel pins, see Section 1.6: "CC pins: port termination characteristics").

1.4.4 Sink or consumer

This port is able to sink power over VBUS, making use of power (from 5 V to 20 V and up to 5 A), most commonly embedded on a device or UFP. A Consumer must assert an Rd resistor (pull-down resistor: see Figure 5: "USB power delivery architecture") on CC pins.

1.4.5 Dual Role Power (DRP)

A dual role power USB port can operate as a source or a sink. The initial role of the port may be fixed or may alternate between the two port states.

Initially, when operating as a source, the port also assumes the role of DFP; when operating as a sink, the port takes the role of UFP.

The port role may be changed dynamically to reverse power.

1.5 USB-C PD architecture

The USB Power Delivery specification defines the stack architecture with all its layers managing a PD device.


10/55 DocID030479 Rev 2

Figure 5: USB power delivery architecture

As per the USB Power Delivery protocol, a USB DFP is initially a Source and a USB UFP is initially a Sink. When these two entities are connected between them, they start to communicate by means of the configuration channel (CC), while the Source supplies the Sink through the VBUS path. Although USB-PD enables the Source/Sink and the DFP/UFP, the roles may be swapped every time the application requests it.

1.5.1 Device Policy Manager (DPM)

The device policy manager deals with the USB Power Delivery resources used by one or more ports on the basis of the local device policy. It interacts with the policy engines and cable detection entities of the device to implement the local policies for each port.

1.5.2 Policy Engine (PE)

The policy engine interacts directly with the DPM to determine which local policy to apply. Its role is to drive the message sequences according to the sent message and its expected response.

It allows power negotiation by establishing an explicit contract for power exchange. The acceptance or the refusal of a request depends on the response of the DPM with respect to a specific power profile.

The PE also handles the flow of vendor defined messages, allowing the discovery, entry and exit of modes supported by the provider and consumer sides.

1.5.3 Protocol Layer (PRL)

The protocol layer drives message construction, transmission, reception and acknowledgment. It allows the monitoring of message flows and the detection of communication errors.

1.5.4 Physical layer (PHY)

The physical layer is responsible for sending and receiving messages across the CC wire. It consists of a transceiver that superimposes a BMC signal on the wire. It is responsible for managing data over the wire, avoiding collisions and detecting errors in the messages using a Cyclic Redundancy Check (CRC).


DocID030479 Rev 2 11/55

1.6 CC pins: port termination characteristics

The configuration channel (CC) pins are used in the discovery, configuration and management of connection across a USB Type-C™ cable, as well as a communication channel for the PHY layer of the USB Power Delivery.

There are two CC pins in each receptacle, but only one is connected through the cable to establish communication. The other pin can be re-assigned as the VCONN pin for powering electronics in the USB Type-C™ plug of electronically-marked cables.

Specific Rd and Rp resistor values connected to CC pins allow single role or dual role system configuration. The attachment and orientation detection operations are carried out through CC lines through these resistors:

a source must assert Rp pull-up resistors on both CC1 and CC2

a sink must assert Rd pull-down resistors on both CC pins

a dual role power (DRP) is equipped with both Rp pull-up resistors and Rd pull-down resistors on its CC pins and is able to dynamically assert the appropriate resistors when the role is fixed by the application according to the operated power role.

A full-featured USB Type-C cable must assert Ra pull-down resistors on the VCONN pin.

The following table provides the values to be used for Rp or current source.

Table 2: Source CC termination (Rp) requirements

Source

Current Capability

Current Source

to 1.7 V - 5.5 V

Rp pull-up

to 3.3 V ±5%

Rp pull-up

to 4.75 V - 5.5 V

Default USB power 80 µA ±20% 36 kΩ ±20% 56 kΩ ±20%

1.5 A at 5 V 180 µA ±8% 12 kΩ ±5% 22 kΩ ±5%

3.0 A at 5 V 330 µA ±8% 4.7 kΩ ±5% 10 kΩ ±5%

Rp resistors connected to both CC pins may be pulled-up to 3.3 V or 5 V. The resistor value is chosen on the basis the device port supplying capability. Moreover, if the source role is operated, the Rp resistors can be replaced by current sources.

The following table provides the values to be used for Rd or Sink CC termination.

Table 3: Sink CC termination (Rd) requirements

Rd setting Nominal Value Max Voltage on pin Power Capability detection

±20% voltage clamp 1.1 V 1.32 V No

±20% resistor to GND 5.1 kΩ 2.18 V No

±10% resistor to GND 5.1 kΩ 2.04 V Yes

Rd resistors may be implemented in multiple ways.

1.7 Power options

Regarding power exchange, every platform equipped with a Type-C™ connector but without power delivery must be able to support 5 V with one of the specific current capabilities. When power delivery is supported and the design is specifically optimized for managing high power loads, the same platform may support up to 20 V at 5 A (100 W).

1.8 Cable attachment and detachment detection and orientation

As stated in the USB Power Delivery specification, it is mandatory to determine the orientation of an attachment; i.e., when one of the two CC pins detects a valid Rp/Rd connection.

To detect an attachment, the source monitors both CC pins.

The pins are floating when nothing is attached, but when the sink is attached via the cable, one CC line of the source is directly pulled-down (through the sink Rd), signalling that a connection has been made (see Figure 6: "Pull up/down CC detection").

Hence, once connection is established, a voltage divider is set between source pull-up resistor Rp and sink pull-down resistor Rd, fixing the voltage level on the CC line for the communication signals.

Figure 6: Pull up/down CC detection

At the same time, the orientation of the plug, and consequently of the cable, is defined according to which CC line (CC1 or CC2) detects a valid resistance after the attach event.

The figure above shows an unflipped cable orientation.

Moreover, the full-featured cable, exposing an Ra resistor, connects the VCONN pins to ground.


DocID030479 Rev 2 13/55

1.9 Power negotiation

When a connection is made and the respective roles have been assigned, the source and the sink negotiate a contract for the power objects: the selected configuration channel (CC) allows them to establish communication and negotiate the power according to the protocol described in USB Power Delivery specification.

Originally, all the devices equipped with USB Type-C™ are able to provide up to 15 W (5 V and up to 3 A) power via the VBUS path, but every subsequent request for delivering or receiving power from 15 W to 100 W (5 V at 3 A to 20 V at 5 A) must be negotiated according to the USB Power Delivery protocol.

The messages exchanged between a source (provider) and sink (consumer) are illustrated in Figure 7: "Message flow during power negotiation".

1. Initially, the source dispatches a Source_Capabilities message to inform the port

partner (sink) of its power capabilities.

2. The sink then sends a Request for one of the advertised power profiles.

3. The source accepts or rejects this request according to its power balance.

4. If confirmed, the source sends an Accept to the sink

5. The source then switches to the requested power profile and sends a PS_Ready

confirmation message.

Each received message is acknowledged with a GoodCRC to confirm correct reception.

Incorrect reception should be ignored and persistent communication errors should trigger a soft reset to reset protocol parameters and re-establish communication. If the error persists, a hard reset is performed.


14/55 DocID030479 Rev 2

Figure 7: Message flow during power negotiation

1.10 Full-featured Type-C™ cable and VCONN supply

Full-featured Type-C™ cables are Type-C™ to Type-C™ cables that support USB2.0 and USB3.1 data operation, and include sideband use (SBU) wires.

All USB full-featured Type-C cables must be electronically marked and must provide 800 Ω to 1.2 kΩ impedance (Ra) that connects the assigned VCONN pin to ground.

When a full-featured cable is attached to a source, the source must provide a VCONN (5 V default) to supply it (valid voltage range is 3 V to 5.5 V).

Up to 1 W may be drawn from VCONN to power the ICs in the plug, necessary to implement electronically-marked cables and VCONN-powered accessories.


DocID030479 Rev 2 15/55

The VCONN is systematically assigned to the free CC pin of the receptacle after a connection is established: the CC pins can be monitored to verify a valid Rp/Ra connection and then the VCONN supply is routed by the source to the checked pin.

Since all the full-featured Type-C™ cables are reversible, both CC pins in the receptacle must be able to assume the role of CC and VCONN on cable insertion.

1.11 Alternate modes and billboard device class

The USB Power Delivery specification supports alternate mode (Alt Mode) to transfer high-speed data over Type-C™ cables using protocols like:

High-Definition Multimedia Interface (HDMI)

DisplayPort (DP)

Peripheral Component Interconnect Express (PCI Express)

Ethernet over twisted pair (Base-T Ethernet)

Mobile High-Definition Link (MHL)

The adoption of alternate mode lets Type-C hosts and devices incorporate additional functionality, exploiting USB PD structured vendor defined messages (Structured VDMs) to manage typical display controller selection mechanisms: discover, enter and exit.

As alternate modes do not traverse the USB hub topology, they may only be used between a directly connected host and device.

Structured VDMs may also be used for re-assignment of the pins that the USB Type-C connector exposes.

Figure 8: Pins available for reconfiguration on the plug of the full-featured cable

The following figure shows the pins available for reconfiguration with direct connect applications. There are three more pins because this configuration is not limited by the cable wiring.

Figure 9: Pins available for reconfiguration on the receptacle for direct connect applications

Where no equivalent USB functionality is implemented, the device must provide a USB interface exposing a USB billboard device class to identify the device. This is not required for non-user facing modes (e.g., diagnostic modes).


16/55 DocID030479 Rev 2

The USB billboard device class definition describes how to communicate the alternate modes supported by a device container to a host system, including string descriptors that provide supporting information in a human-readable format.

Figure 21: P-NUCLEO-USB002 expansion board Port 1 Current sensing stage schematic view

Although the STUSB1602 monitors the VBUS voltage, a resistive voltage divider for voltage sensing managed by the STM32F072RBT6 ADC peripherals, has been added. This option, matched with the current sensing stage, provides the alternative of measuring power with the microcontroller.

2.3.2 P-NUCLEO-USB002 expansion board: STUSB1602 USB Type-C controller

The STUSB1602 device is a 20 V technology USB Type-C™ controller IC, designed to establish and manage the connection between two USB Type-C ports, according to the configured power role (source, sink or dual role power).

It is fully compatible with:

USB Power delivery specification (rev2.0)

USB type-C™ cable and connector spec (rev1.2)

Each STUSB1602 device interfaces with a Type-C port and interacts with the VBUS management block and the microcontroller.

The Type-C port interface allows implementation of the lower level functions of the PD firmware stack, including:

detecting the connection between two USB Type-C ports (attach detection)

managing BMC coding and decoding

establishing a valid source-to-sink connection

determining the attached mode: source, sink or accessory

resolving cable orientation and twist connections to establish USB data routing (mux control)

configuring and monitoring the VBUS power path

managing the VBUS power mode: USB Default, Type-C Medium or Type-C High current mode

configuring VCONN when required

It also supports dead battery and low power standby modes as well as providing high voltage protection and debug accessory support.

Figure 22: STUSB1602 front end for Port 0

This circuit description uses port 0 for reference (see Figure 22: "STUSB1602 front end for Port 0"), but the same applies to port 1.

The STUSB1602 device interacts with the STM32F072RBT6 microcontroller embedded in the NUCLEO board via the following communication buses:

1. I²C bus: is used by the MCU to configure and control status of the device. This bus is shared by both STUSB1602 devices, according to their I²C addresses (ADDR0). Additionally, the STUSB1602 start-up profile can be fully customized by accessing its integrated non-volatile memory via I²C.

2. SPI peripheral: is reserved for USB-PD messages. The BMC transceiver on the STUSB1602 means that messages exchanged between the MCU and STUSB1602 are 5B coded (except the Preamble, as per the USB-PD specification).

The following MCU GPIOs are used for specific functions for each STUSB1602 device:

1. TX_EN is a control signal from the MCU to STUSB1602. It enables the BMC control logic that will transfer data from the MCU serial interface, encode in BMC format and drive the connected CC line.

2. ALERT signals specific events regarding CC detection, monitoring and fault condition groups to the microcontroller. Each of these groups of events can be masked configuring specific I²C registers.

3. A_B_SIDE pin provides cable orientation; this is also provided by an internal I²C register.

4. RESET allows resetting of the device; this can be also accomplished via a specific I²C register.

CC1 and CC2 configuration channel pins are for connection and attachment detection, plug orientation and system configuration management across the USB Type-C cable.

CC1DB and CC2DB are for dead battery mode when the STUSB1602 is configured in the sink power role or dual power role. This mode allows systems powered by a battery to be supplied by VBUS when the battery is fully discharged.

This mode is enabled by connecting CC1DB and CC2DB respectively to CC1 and CC2. Thanks to this connection, the pull-down terminations on the CC pins are present by default even if the device is not supplied.

When an STUSB1602 device configured in dead battery mode is connected to source, it is supplied via its VDD pin connected to VBUS on the USB Type-C receptacle side. The STUSB1602 may establish the source-to-sink connection by enabling the power path on VBUS.

When the STUSB1602 assumes the sink power role, the VBUS_EN_SNK pin allows the enabling of the incoming VBUS power when the connection to a source is established and VBUS is in the valid operating range. Similarly, in the source power role, the VBUS_EN_SRC pin allows the enabling of the outgoing VBUS power when the connection to a sink is established and VBUS is in the valid operating range.

In both cases, the open drain output of the VBUS_EN_SNK and VBUS_EN_SRC pins allow the direct driving of a PMOS transistor. The logic value of these pins is also advertised in a dedicated I²C register bit.

2.3.3 P-NUCLEO-USB002 expansion board: VCONN switch

The VCONN input power pin of STUSB1602 is connected to pins CC1 and CC2 across independent subscript for CONN power switches. The VCONN voltage provided to the STUSB1602 device can be supplied via the power connector or the local voltage regulator according to the JP000 and JP001 jumper settings below.

Table 6: P-NUCLEO-USB002 expansion board VCONN settings

VCONN is provided by the local voltage regulator

VCONN is provided by the power connector


DocID030479 Rev 2 29/55

Figure 23: P-NUCLEO-USB002 expansion board: JP000 and JP001 jumper settings to provide VCONN through the local voltage regulator

The VCONN voltage is only applied to the CC pin that is not connected to the CC wire after:

the device is configured in source power role or dual role power (DRP)

VCONN power switches are enabled

a valid connection to a sink is achieved

Ra is detected on the unwired CC pin

a valid power source is applied on the VCONN pin with respect to a pre-defined UVLO threshold.

VCONN discharge is automatically managed by STUSB1602.

VCONN protections can be configured via a dedicated control register (see STUSB1602 datasheet on www.st.com).

2.3.4 P-NUCLEO-USB002 expansion board: VBUS management

Figure 24: P-NUCLEO-USB002 expansion board Port 0 schematic view of the VBUS management mechanism

Figure 25: P-NUCLEO-USB002 expansion board Port 1 schematic view of the VBUS management mechanism

This circuit description uses port 0 for reference, but the same applies to port 1.

The VBUS management block can manage different VBUS, as described by USB PD specification. It provides energy if the STUSB1602 is set as a provider and supplies energy when it is a consumer.

Transistors Q401 and Q402 are set in back-to-back configuration to protect and isolate the VBUS supplying path in both directions.

When the port acts as a provider, the VBUS power can be supplied via power connector CN4 (jumper JP400 must be left open). VBUS is put on the supply path via the discrete load switch (Q401-Q402), driven by the STUSB1602 VBUS_EN_SRC pin.

If no external power supply is available, closing jumper JP400 allows using the 5 V from the NUCLEO-F072RB board as VBUS in the provider role only. This is mainly used for demonstration purposes.

When the port is a consumer, the same VBUS path is managed by the VBUS_EN_SNK pin of the STUSB1602 device that enables the discrete load switch Q416.


DocID030479 Rev 2 31/55

The STUSB1602 monitoring block handles the internal VBUS discharge path connected to the VBUS_SENSE input pin. The discharge path is activated on a detach event or when the device enters the error recovery state, regardless of the power role.

The VBUS discharge to 0 V path is enabled by default over a time interval that can be modified via dedicated I²C registers.

The exposed Rp value that advertises the current capability may be set on the STUSB1602 by registers (i.e., SINK_POWER_STATE).

2.3.5 P-NUCLEO-USB002 expansion board: local power management stage

This stage does not contain any power blocks to derive multiple voltage profiles from a single input voltage source. To implement such a solution, the user must connect appropriate external circuitry, under their own responsibility, to the P-NUCLEO-USB002 expansion board CN4 power connector.

The P-NUCLEO-USB002 expansion board is designed to provide power to the connected platforms via:

1. An external power supply: this may supply high power levels. If the external power supply is connected to connector CN4, JP400 and JP401 must be open; VBUS will be a voltage level offered by the external power supply board

2. The standard USB port through connector CN1 on the NUCLEO-F072RB board. The maximum available power is the 5 V 500 mA currently offered by the standard PC USB; jumper JP400 or JP401 or both must be closed

The local power management stage consists of the following sets of load switches implemented by the MOSFETs transistor:

1. Q500-Q501 enabled by Q505 2. Q502-Q503 enabled by Q506

Similarly, the STM32F072RBT6 MCU can act on DRP and /DRP lines enabling the DC-DC converter L6984 (U500).

Figure 26: P-NUCLEO-USB002 expansion board: schematic view of the load switches of the local power management


32/55 DocID030479 Rev 2

Figure 27: P-NUCLEO-USB002 expansion board: schematic view of the local DC-DC converter

This stage is able to supply different voltage levels to the system according to the USB PD specification. Q500-Q501 and Q502-Q503 are set in back-to-back configuration and permit isolation in both directions of the supplying path.

It is indeed possible to supply the platform from VBUS via a provider connected to one of the ports or from VIN via power connector CN4: the two independent power paths are directly controlled by the STM32F072RBT6 MCU through the DRP and /DRP functions.

When the platform is the consumer and receives VBUS on one of the two ports, diodes D501 and D502 deliver VBUS to the Q500-Q501 load switch and then supply the DC-DC converter, and hence the system.

2.3.6 P-NUCLEO-USB002 expansion board: STSAFE secure device

The STSAFE™-A100 device on the P-NUCLEO-USB002 expansion board provides authentication and secure data management services.

It is mounted on a device that authenticates a remote host or on a peripheral that authenticates the local host itself, legitimating communication between the two entities.

As the STSAFE-A100 is provided with a host library that can be ported to a wide range of microcontrollers, there is an exclusive I²C link between the device in P-NUCLEO-USB002 expansion board and the MCU in the NUCLEO-F072.

The STSAFE capabilities can therefore authenticate single port communication or ensure the integrity of the whole platform (dual port solution).

2.3.8 P-NUCLEO-USB002 expansion board: ESD protections

The P-NUCLEO-USB002 expansion board features USB protections on:

1. VBUS: each port is protected by an SMM4F24A Transil, designed to protect sensitive equipment against electro-static discharges

2. CCx lines: each CC line is connected to an ESDALC5-1BF4 providing low clamping, low capacitance, bidirectional, single line ESD protection

3. USB2.0 pins: the USB pins of both ports are connected to a USBLC6-2 ESD protection for high speed interfaces (USB 2.0, Ethernet links and video lines) with high integrity while still protecting sensitive chips against the worst ESD strikes

2.3.9 P-NUCLEO-USB002 expansion board: connectors

2.3.9.1 VBUS load connectors

Connectors CN11 and CN12 for port 0 and port 1 are able to supply VBUS externally to power any load connected to them.

2.3.9.2 Extension Connectors

Both ports support the USB PD and the USB Type-C™ specification, including the alternate-mode capability. For this reason, connectors CN13 and CN14 for port 0 and port 1 are available to expose all the main pins and facilitate the design of applications using this mode.

Figure 30: P-NUCLEO-USB002: CN13 and C14 connector pinout

2.3.9.3 Power connector

The P-NUCLEO-USB002 power connector CN4 on the rear of the board connects the expansion board to a selectable power supply with appropriate voltage and current couples for the USB PD specification.

The pairs 1 and 3 as well as 2 and 4 can externally supply the VBUS management circuits from a power board to the two Type-C™ receptacles CN0 and CN1.

Pairs 9 and 11 as well as 10 and 12 can select the external power requested by the application. In particular, the default GPIO functionality assigned to pins 9 and 11 can be changed to I²C SDA and I²C SCL respectively if the external power board acts as smart power supply.

Enable and discharge pairs 13 and 15 as well as 14 and 16 can control any external power supply board load switches available. A pair of POWER GOOD pins check whether the power supply is ready to provide the requested power range.

Power connector CN4 is also able to provide the VCONN voltage if the external power supply board supports that functionality.

Finally, the VSYS system supply voltage be the voltage input for the embedded DC-DC converter.


36/55 DocID030479 Rev 2

Figure 31: P-NUCLEO-USB002: CN4 connector

2.3.9.4 Serial communication connector

The P-NUCLEO-USB002 expansion board embeds the CN2 connector that exposes the USART1 peripheral of the STM32F072RBT6 MCU when the expansion board is plugged to the NUCLEO-F072RB board.

This allows exploiting the serial communication to send commands to the NUCLEO-F072 MCU or access to the application data.

Since the ST-LINK contained in the NUCLEO-F072 board may be used as a Virtual COM port, accessible by the CN3 connector, the expansion board CN2 connector can be connected to the NUCLEO-F072 CN3 connector via two female wires (included in the blister). It is also possible to retrieve the application data through a serial/TCP terminal.

The following table and the figure below provide more information on how to set up the serial communication connection.a

UM2191 System setup

DocID030479 Rev 2 39/55

3 System setup

For each configuration, the P-NUCLEO-USB002 expansion board must be stacked on the NUCLEO-F072RB board through the ST morpho connector, paying attention to the mounting direction and alignment of the two boards, as per the following figure.

Figure 33: P-NUCLEO-USB002 mounting orientation

3.1 Source power role configuration

3.1.1 Using the NUCLEO-F072 on-board voltage regulator

When the P-NUCLEO-USB002 kit is connected to a PC or a standard USB power supply via a USB Type-A to Mini-B cable plugged to CN1 connector, the on-board NUCLEO-F072RB voltage regulator supplies the entire system and provides (5 V) VBUS.

To deliver the VBUS on the selected port from the NUCLEO-F072RB USB PWR voltage (CN1 connector):

on NUCLEO-F072RB board:

JP1 open

JP5 (PWR) closed on U5V (fitting pins 1-2)

JP6 (IDD) closed

on P-NUCLEO-USB002 expansion board:

JP400 and JP401 (relative to PORT_0 or PORT_1) closed

3.1.2 Using an external power supply

If an external power board is connected to the P-NUCLEO-USB002 expansion board power connector CN4, the provider can offer different VBUS voltage profiles. The Provider configuration is:

System setup UM2191

40/55 DocID030479 Rev 2


JP1 closed

JP5 (PWR) closed on E5V (fitting pins 2-3)

JP6 (IDD) closed


JP400 and JP401 (relative to PORT_0 or PORT_1) open

Once configured, if a full-featured cable is used, verify that on the selected port the VCONN jumpers (JP000 and JP001) on the P-NUCLEO-USB002 expansion board are configured according to the preferred voltage delivery mode:

fit pins 1-2 of JP000 and JP001 to select VCONN provided by the +5 V generated by NUCLEO-F072RB board

fit pins 2-3 of JP000 and JP001 to select the VCONN provided by the external power supply through the CN4 power connector

3.2 Sink power role configuration

In the Consumer configuration, the system may manage two supply options.

The first one is supplied by the NUCLEO-F072RB board, while the second configuration is more interesting from the application point of view, since it implements a specific feature of the USB PD solutions, i.e. the Dead Battery mode (when a Consumer is supplied by the Provider by mean of its VBUS). Both configurations correspond to two diverse settings, too:

3.2.1 Using the NUCLEO-F072RB on-board voltage regulator

When the P-NUCLEO-USB002 kit is connected to a PC or a USB power supply by NUCLEO-F072RB CN1 connector, the on-board voltage regulator supplies the system.

In this case, the system setting:


JP1 open


JP6 (IDD) closed


VBUS jumpers JP400 and JP401 open

VCONN jumpers JP000 JP001 open

3.2.2 Using an external provider

This configuration allows applications to implement a specific feature of the USB PD solutions: the Dead Battery mode.

If the Consumer is supplied by the VBUS delivered by the connected Provider through the USB Type-C™ cable, the system setting is:


JP1 closed


JP6 (IDD) closed


VBUS jumpers JP400 and JP401 open

VCONN jumpers JP000 JP001 open

UM2191 System setup

DocID030479 Rev 2 41/55

3.3 Dual Role Power configuration

The DRP configuration setting ensures operation as both provider and consumer.

As the provider configuration setting ensures the correct VBUS and VCONN management, the DRP configuration setting is the same as described for the Provider.

3.3.1 Using the NUCLEO-F072RB on-board voltage regulator

When the P-NUCLEO-USB002 kit is supplied by the on-board NUCLEO-F072RB voltage regulator, via a USB Type-A to Mini-B cable plugged to the NUCLEO board CN1 connector and then to a PC or a standard USB power supply.

The system setting is:


JP1 open


JP6 (IDD) closed


JP400 and JP401 (relative to PORT_0 or PORT_1) closed

3.3.2 Using an external power supply

Connect an external power board to the P-NUCLEO-USB002 power connector CN4 so the system can offer different VBUS voltage profiles.

In this case, the system configuration is:


JP1 closed


JP6 (IDD) closed


JP400 and JP401 (relative to PORT_0 or PORT_1) open

Once configured, if a full-featured cable is used, verify that on the selected port the VCONN jumpers (JP000 and JP001) on the P-NUCLEO-USB002 expansion board are fit according to the preferred voltage delivery mode:

fit pins 1-2 of JP000 and JP001 to select VCONN provided by the +5 V generated by NUCLEO-F072RB board

fit pins 2-3 of JP000 and JP001 to select the VCONN provided by the external power supply through the CN4 power connector
