X-CUBE-UCSI is an STMicroelectronics original initiative. It uses for USB Type-C and Power Delivery software expansion for STM32Cube (UM2285).
X-CUBE-UCSI package consists of libraries, drivers, sources, APIs, and application example running on STM32G0 32-bit microcontroller acting as an UCSI (USB Type-CTM Connector System Software Interface) Platform Policy Manager (PPM) on the STM32MP135F-DK board. The PPM is a combination of hardware and firmware that manages the USB Type-C connectors on the platform. The STM32MP13 has a role of UCSI OS Policy Manager (OPM) to interface with the PPM, via I2C with the UCSI interface.
This application also features the TCPP02-M18/TCPP03-M20 USB Type-C port protection device. To discover all the MCU-based solutions for USB Type-C™ and Power Delivery technology, go to the landing page https://www.st.com/content/st_com/en/stm32-usb-c.html.
The figure below shows the overall architecture:
- STM32MP135F-DK
| Applications | Board | MCU | Short Description |
|---|---|---|---|
| UCSI_DRP | STM32MP135F-DK | STM32G071G8 | Use of USB Power Delivery (USB-PD) Dual role application running on STM32G0XX devices. |
This Expansion Package is demonstrated on one hardware implementation, but can easily be ported to any STM32 including the UCPD peripheral.
