STEVAL-2STPD01 HW Overview

Dual Port solution architecture may be divided in two sub-systems:
• the “digital” stage, identified as the STM32 Nucleo-64 development board NUCLEO-G071RB that embeds the STM32G071RB;
• the “power” stage, identified as the expansion board, that physically manages, redirects, and converts the input supply to the main
functional blocks of the solution, contributing also to output the expected voltages.

Main SW functional layers are:
1. Hardware abstraction
−STM32CubeG0 HAL HardwareAbstraction Layer for the
STM32G0 microcontroller.
−Board Support Package (BSP) library layer containing the
drivers of the STPD01 and TCPP02-M18 devices.
2. Middleware
−USB PD Library containing the ST USB-PD middleware stack
main blocks (Policy Engine,Protocol Layer,Physical Layer,
USB-C port Control)
3. Application
−Device Policy Manager to manage USB power delivery resources
in the platform
−Power Monitor to monitor, at higher level, the bus status acquiring
the voltage-current pair and reaching events
−Power Sharing, a specific IP to distribute the power between the
two ports, starting from the Power input budget and considering the
operative status of each port

Setup & programming
the STEVAL-2STPD01

•Available Input Power:
‒The board has been designed to offer 60W for
each port, with the largest list of available PDOs:
20V, 15V, 9V and 5V @ 3A.
‒To permit the board to provide the max rated
power (120W), the minimum available input power
must be >144W, with a minimum voltage of 21V.
‒The board can be supplied through two different
connectors:
‒The DC Power Jack J800 that can absorb
5A maximum.
‒The DC Power Connector J801 able to sustain more
than 10A.

(*): any DC power supply that allows the board to provide up to 120W output power (60W on each port), must be connected to the DC
Power Connector J801.

Instructions:
•Unpack and turn-on the STEVAL-2STPD01: the board has been
already programmed for you!
•Connect the board to a DC source through the DC Power Jack
(J800) or the DC Power Connector (J801)(*).
•First the red LED D201 tuns ON and, the LED LD4 on the
NUCLEO-G071RB board starts to blink fast.
•After few milliseconds, the application runs turning ON all the
LEDs (D400, D401, D600 and D601) on the expansion board, and
the LED LD4 on the NUCLEO-G071RB board starts to blink
slowly.
• If the power supply isn’t rated as 24V, 6A (i.e. Default value saved
in the STM32G071RB Flash), the Input Power Setting (Voltage
and Current) must be fixed in the application setting values (see
next slide).
•Finally, the board is ready to be connected to one or two Sink
platforms.
How to Setup the STEVAL-2STPD01

(*): a 24V,6A DC power supply, universal inputAC 110-240V (brandedArotelicht, model CJ-2460) has been used to generate up to 60W per port

Instructions
This procedure permits to set the Input Power data different from
the Default value (24V, 6A), to be compliant with the user power
supply specification:
•Download and install the STM32CubeMonitor-UCPD from the ST
site.
•Connect the power supply to one of the two STEVAL-2STPD01
power connectors (J800 or J801)
•Connect the NUCLEO-G071RB USB_STLINK CN2 connector (of
the STEVAL-2STPD01), to the PC through a micro-B USB cable.
•Open the STM32CubeMonitor-UCPD program
•Select the board STEVAL-2STPD01
•Select one Port (1 or 2)
