STMicroelectronics X-NUCLEO-USBPDM1

Overview

X-NUCLEO-USBPDM1 from STMicroelectronics is a USB Type-C™ Power Delivery sink expansion board based on the TCPP01-M12 port protection IC, designed for STM32 Nucleo-64 development boards (NUCLEO-G071RB and NUCLEO-G474RE). It supports 100 W programmable power supply (PPS), complies with USB Type-C™ Rev 1.2 and USB Power Delivery 3.0, and provides 6 V overvoltage protection on CC lines and up to 22 V adjustable OVP on VBUS.

For engineers reviewing the X-NUCLEO-USBPDM1 datasheet, X-NUCLEO-USBPDM1 pinout, X-NUCLEO-USBPDM1 application, or X-NUCLEO-USBPDM1 equivalent, this board enables rapid evaluation of USB-C PD sink functionality-including dead-battery management, system-level ESD protection per IEC61000-4-2 Level 4 (±8 kV contact), low-power mode with zero current draw when unplugged, and integrated 3.3 V LDO for board power.

Technical Context

The X-NUCLEO-USBPDM1 implements a complete USB-C PD sink interface using the TCPP01-M12 as its core controller, handling UCPD communication, CC line monitoring, VBUS fault detection, and power path control. It interfaces directly with STM32 GPIOs (e.g., PA4_G0/PA5_G0 for CC1/CC2) and ADC channels (ADC_VBUS) for real-time voltage sensing.

Its hardware design includes discrete surge suppression on VBUS, common-mode filtering and ESD protection on USB 2.0 data lines (DP/DM), and dedicated FLT_IN/FLT signals tied to the TCPP01-M12's fault reporting logic-enabling robust overtemperature, overvoltage, and short-circuit response in embedded PD evaluation.

FAQ

Is X-NUCLEO-USBPDM1 still in production?

No - STMicroelectronics has discontinued the X-NUCLEO-USBPDM1 for new purchases. Its functional successor is the X-NUCLEO-SNK1M1, which adds enhanced features while maintaining compatibility with STM32 Nucleo-64 boards and full USB PD 3.0 compliance.

Which STM32 Nucleo boards are compatible with X-NUCLEO-USBPDM1?

The board is validated for use with NUCLEO-G071RB and NUCLEO-G474RE. It supports any STM32 Nucleo-64 board equipped with a USB Type-C™ peripheral and accessible GPIOs for CC line monitoring (e.g., PA4/PA5) and ADC_VBUS sensing.

Does X-NUCLEO-USBPDM1 provide VBUS power to the host Nucleo board?

Yes - it integrates a 3.3 V LDO (ST715PU33R) powered from VBUS, enabling the expansion board to supply regulated 3.3 V to the Nucleo board via the Arduino Uno R3 connector, eliminating need for external power during PD sink testing.

What software support is available for X-NUCLEO-USBPDM1?

ST provides the X-CUBE-TCPP software expansion package for STM32Cube, including USB-C PD stack, TCPP01-M12 driver APIs, and example projects for sink mode operation, dead-battery recovery, and PPS negotiation on supported Nucleo platforms.
