Implement new USB Type-C and Power Delivery technology with ST certified embedded software solution based on STM32.

The free STM32 USB-C and PD stack is compliant with USB Type-C 1.2 and USB Power Delivery 2.0 specifications enabling the rapid development in end-products, benefiting of the rich feature set of STM32 Cortex-M based MCU.

The new firmware stack, X-CUBE-USB-PD, initially based on STM32F0 entry level Cortex-M0,  allows designers to upgrade their USB legacy devices to provide significant benefits to their end users. USB-C together with Power Delivery technology provides a reversible connector, the ability to carry all necessary data (including video or proprietary protocols), and up to 100W of power to supply or charge equipment connected to the USB port.en_STM32_USB_CPD_P3825S_big.jpg

The successful STM32 family sets the standard for embedded processing, from the smartest phones and tablets to the smallest Internet-of-Things applications. “It offers the world’s widest range of price/power/performance options for the de facto industry-standard embedded-processor architecture, backed up by a comprehensive design ecosystem that includes no-cost software and low-cost development boards that minimize time to market and maximize ROI.”

Important benefit in terms of cost and PCB footprint is that solutions using STM32 with the stack require only a very simple Analog Front End comprising a few passive components, because it fully exploits STM32 embedded features such as comparators, ADCs, timers, and Direct Memory Access.

Other key technical features and benefits of ST’s solution include:

  • Support for up to two USB-C ports (provider, consumer, or dual role);
  • Cable-insertion detection, plug orientation;
  • Identification of the role of the port partner attached and its current capability;
  • Vbus Power negotiation via Power Delivery communication protocol;
  • Vendor-Defined Messages are handled to identify device or cable ID or to manage Alternate Mode commands;
  • Maximum flexibility and adaptability versus evolving specification changes, as firmware upgrades are possible during the application lifetime;
  • The processing bandwidth and available resources allow the MCU to perform other application-specific tasks, such as power-management control, USB2.0 communication, and/or voltage and current monitoring, on top of its USB-C functionality;
  • Software library provided in the X-CUBE-USB-PD software expansion is fully in line with STM32Cube APIs (HAL - Hardware Abstraction Layer), ensuring easy switch across different STM32 series;
  • Best time-to-market with market-proven solutions already deployed by industry leaders.

ST supports the new USB-C technology with an STM32 Nucleo Pack as a discovery and development tool to minimize design effort The pack includes a  NUCLEO-F072RBNUCLEO-F072RB board a USB-C and PD expansion board and a full-featured USB Type-C cable The expansion board features two Dual-Role Power USB Type-C ports with a discrete Analog Front End

The STM32F0 USB-C and PD Nucleo Pack (P-NUCLEO-USB001) is available at a unit price of U$49.90.

Engage with ST, join the contest!  in collaboration with ARM Connected Community ST is organizing the STM32 Internet of Things Design
Contest  EMEA Edition
.
We believe in the creativity of engineers and challenge them to invent the next big Thing for IoT, to design around the STM32 family of ARM® Cortex®-M microcontrollers and ST’s other industry-leading components
. ST will assist the finalists in turning their dreams into reality with technical
support during the development phase and can help in bringing the winning solution to market.

You can register for this exciting contest and send us a project description and a video of your innovative application (all information into Terms&Conditions). You could be one of the three lucky winners to be invited at an award ceremony at Electronica in Munich to collect your prize: a Hyetis Crossbow - the first and only Swiss Made Luxury SmartWatch.
Contest Rules
Candidates are challenged to develop an Internet of Things application based on at least one STM32 microcontroller and as many other ST components as possible (at least one other required). Registration and submission of projects are open on ST Facebook.
An ST panel will select ten project finalists based on the following criteria: level of innovation, ST product content, feasibility, functionality, technical merit, usefulness.
The videos describing the finalists applications will be posted mid September on the web site and three winners will be elected by the “embedded community”with a voting system open until end of October.

The winners will be invited to attend an award Ceremony during Electronica in Munich - November 11th-14th.
