STMicroelectronics‘ latestX-CUBE-TCPP software packenhances the company’s portfolio of USB Type-C port-protection ICs and STM32 interface IP (intellectual property) to simplify product designs leveraging the USB Power Delivery specification.
USB Power Delivery supports operating modes from legacy 5V/0.5A up to 48V/5A (240-Watt) in the latest Revision 3.1 specification. The expanded power capacity inspires innovative product design and assists new sustainability legislation.
One example is the recent EU agreement for USB Type-C to become the common charging port in all mobile phones, tablets, and cameras to reduce electronic waste. New product designs that leverage USB Power Delivery include power banks, smart speakers, PC peripherals, communication equipment, medical devices, POS terminals, industrial displays, and battery-powered embedded applications.
ST’s X-CUBE-TCPP software pack eases development in the STM32Cube ecosystem and provides libraries for the threeUSB Type-C port-protection ICs. These are the TCPP01-M12 for sink applications, the TCPP02-M18 for source applications, and the TCPP03-M20 for dual-role power (DRP) applications.
TheTCPP01-M12,TCPP02-M18, andTCPP03-M20work with ST’s UCPD (USB Type-C and Power Delivery) interface IP featured in selected STM32G0, STM32G4, STM32L5, and STM32U5 microcontrollers (MCUs). They address USB Power Delivery in the standard power range, up to 20V-5A (100 Watt). This partitioning of the USB Type-C implementation between the MCU and port-protection IC enables a two-chip solution that saves cost, reduces complexity, and minimizes PCB space. The STM32 device also performs as the host MCU.
Additionally, X-CUBE-TCPP assists development on STM32 MCUs that do not contain the Power Delivery PHY, to streamline compliance with the USB Type-C specification.
Users can accelerate development of sink applications by using the X-CUBE-TCPP libraries with theX-NUCLEO-SNK1M1expansion board and any STM32 Nucleo-64,NUCLEO-G071RB,NUCLEO-G474RE, orNUCLEO-L412RB-P development boardcontaining an STM32 MCU that executes the code.
对于源应用程序,X-CUBE-TCPP库can be used with the X-NUCLEO-SRC1M1 expansion boardand any STM32 Nucleo-64 development board for USB Type-C source without Power Delivery, or the NUCLEO-G071RB or NUCLEO-G474RE for USB Type-C source with Power Delivery. The libraries for DRP applications with Power Delivery are used with the X-NUCLEO-DRP1M1 expansion boardconnected to a NUCLEO-G071RB or NUCLEO-G474RE.
The three boards are certified by theUSB Implementers Forumand have a Test ID (TID) number that confirms compliance with the USB-C Power Delivery specification. This assures developers of interoperability with other certified products in the field. The TIDs for the boards areX-NUCLEO-SNK1M1(TID 5205),X-NUCLEO-SRC1M1(TID 7884), andX-NUCLEO-DRP1M1(TID 6408).
The X-CUBE-TCPP software packis ready to download free of charge fromst.comor GitHub.
