Based on STMicroelectronics STM32G0 MCU, SL-PRIPM09404V1This USB Type-C™ and Power Analyzer is designed to reduce the cost and complexity of USB Type-C™ communication and power application development and debugging. The solution provides all the necessary interfaces for instant connectivity and communication with other USB Type-C™ devices, as well as access to port characteristics such as: data role, power role, VBUS and IBUS monitoring.

The solution is based on the STM32G0 certified USB-C Power Delivery 3.0 microcontroller running the STM32CubeMonUCPD software analyzer to monitor and configure USB Type-C and Power Delivery applications. Supports USB Type-C Interface™ 1.2 and USB PD 2.0/3.0 specifications, and can perform in standalone sink mode or spy mode.

In spy mode, all CC1 and CC2 communication signals between two Type-C products can be serially and passively captured. It does not interfere with any USB 3.1 Gen 2 or USB 2.0 signals and allows monitoring of PD power negotiation, USB data roles, and Type-C alternative modes, e.g., DisplayPort. standalone sink mode allows certain protocol operations to be performed.

The STM32G071B-DISCO kit is housed in a plastic enclosure and comes with all the necessary interfaces to easily connect and interact with other USB Type-C™ devices.

The build is based on the STMicroelectronics Arm® Cortex® -M0+ core STM32G071RB USB Type-C™ and Power Delivery microcontroller, running the STM32CubeMonUCPD software GUI to discover and display USB Type-C™ port functions such as: data Role, Power Role, VBUS and IBUS monitoring.

Menus can be scrolled via the 4-way user handle and information can be displayed via the 128 x 64 pixel OLED embedded display.The 8-pin user connector collects all communication signals and allows for additional GPIO expansion.

The solution is available with a comprehensive free software library and examples that can be implemented in STM32Cube™ MCU packages.
