STM32G0B1CBT6 UCPD Development Board

What is STM32 UCPD?
STM32 UCPD (USB Type-C / USB Power Delivery) is a controller integrated into an STM32 microcontroller that supports the USB Type-C interface and the USB Power Delivery protocol. Its main functions include:


USB Type-C connectivity: Supports USB Type-C interface identification and connection management, ensuring devices can correctly identify the type and orientation of the connected cable.


Power Delivery: Supports the USB PD protocol, allowing devices to negotiate voltage and current with the power adapter for more efficient charging and power transfer.


Multiple power profiles: Multiple power profiles can be configured to suit the needs of different devices.


Hardware protection: Improves system safety through built-in overcurrent, overvoltage, and short-circuit protection.


Low-power mode: UCPD can operate in standby mode, reducing power consumption.


By using the STM32's UCPD functionality, developers can easily implement USB Type-C and PD functions, improving device compatibility and charging efficiency.
