STMicro added UCSI library to its STM32Cube to support USB-C
To support development of USB-C Power Delivery (PD) applications on STM32 MCU chips, STMicroelectronics added a USB Type-C connector system interface (UCSI) library in the STM32Cube software ecosystem.
The X-CUBE-UCSI is a turnkey UCSI-certified solution with ready-to-use hardware and firmware examples to implement standardized communication using an STM32 MCU as a UCSI PD controller. These are designs that a customer can simply copy and paste, which have been optimized for its bill-of-materials (BoM). The software lets the MCU connect to the main system processor and exchange information with the operating system using the UCSI protocol, while controlling the USB-C attachment and PD protocol. The main processor, which can be a System-on-Chip (SoC), application processor, or STM32MP microprocessor, acts as the UCSI operating system policy manager (OPM). The PD controller on-board the STM32 MCU performs as UCSI platform policy manager (PPM). The necessary USB type-C and Power delivery (UCPD) peripheral is available in various STM32 MCUs. The lowest-cost variant is the STM32G0 line, making an ideal low-pin-count companion chip for the MPU dedicated to handling the PD functionality. The software also allows STM32 MCU firmware programming via the main processor, in the production line as well as...
