In view of the world more and more electronic products company plans in the new product the USB Type - C ™ and Power transmission (PD, the Power Delivery) technology, across multiple electronic application field, the world's leading supplier of semiconductor STMicroelectronics (STMicroelectronics) released a through industry certification of STM32 micro controller based on its market leading software solutions, let the USB Type - C ™ and Power transmission (PD) integration work easier. This free STM32 USB - C and PD middleware stack compatible USB Type - 1.2 C and USB Power Delivery 2.0 specification, is advantageous for the customer on the final product rapid deployment of the new technology, and make full use of STM32 ARM ® architecture ® -m rich function of microcontroller.

The new firmware stack X - CUBE - USB - PD was originally based on STM32F0 entry-level processor architecture (M0, let the designers to upgrade traditional USB devices, for the use of end users bring great convenience. USB - C and power transmission technology to define a positive and negative can plug connector, can all the required data transmission application function (including video or proprietary protocol), ACTS as a maximum 100 w power or to a USB port and charging equipment.

Stmicroelectronics microcontroller products division, marketing director, Daniel Colonna, said: "our USB - C and power transmission software stack is proved STM32 series products can get such a example of success, in everything from smartphones to iot embedded processing application market set a reference standard. STM32 family of products for the market accepted industry standards for the development of embedded processor architecture community, the world's most, choice of power, performance, price, and behind a full-featured powerful support to the ecosystem, including free software and low-cost development board, helping our clients achieve development cycle to minimize, maximize investment returns."

Cost and printed circuit board space is a new software stack STM32 and solution of important advantage, because the STM32 is rich in function can be used, like voltage comparator, AD converter, timer, and direct to fetch technology, practical design just a made up of a number of passive components simple analog front end.

Stmicroelectronics solution of other important technical features and benefits include:

Supports up to two USB port - C · (power supply, electricity or dual role);

Line inserted into the detection, plug direction detection;

Even devices, to identify the port role and its current capacity;

Build Vbus by PD communication protocol, power dialogue;

Definition of information, processing manufacturers, to identify the device or thread ID, or manage Alternate Mode command;

Flexibility and adaptability of the highest and continuously improve technical specification, in the product life cycle can upgrade the firmware;

Bandwidth and available resources, rich in processing, let the micro controller can perform the function of USB - C other special tasks, such as power management control, USB2.0 communication and/or voltage current monitoring;

, X - CUBE - USB - PD package within the software library and STM32Cube API (HAL - hardware abstraction layer) is completely consistent, to ensure easy transplant between different STM32 series software;

Mature market tested solution, there have been several market leading enterprise deployment, helps speed up the product on the market.

Stmicroelectronics launching a support new USB - C technology STM32 Nucleo Pack function to explore development kit, to minimize development design work. This set of development tools include a NUCLEO - F072RB development board, a USB - C and PD extension board and a fully functional USB cable Type - C. Expansion board, there are two power supply by electricity dual role USB Type - port C and form a complete set of discrete analog front end.

STM32F0 USB - C and PD Nucleo Pack (P - Nucleo - USB001) are listed.
