STMICROELECTRONICS REVEALS STM32 PROGRAMMING/DEBUG PROBE

STMicroelectronics’ STLINK-V3PWR is a new in-circuit debugging and programming probe that provides accurate power measurement suitable for applications running on any STM32 microcontroller (MCU).

Having a wide dynamic range to handle power-conscious projects including IoT and wireless applications, the probe measures current values from nanoamps to 500mA and remains accurate up to ±0.5%. Also, it can supply up to 2A to the target system through a single USB cable, enabling developers to power the board without a separate supply.

STLINK-V3PWR is supported directly within the STM32CubeMonitor-Power graphical tool, which helps visualize the power demands of the application in real-time and analyze the effects of design changes to improve energy efficiency. It is also supported within the Arm^® Keil^® development tool and IAR integrated development environment (IDE), which enable users to synchronize code execution with energy-consumption measurements to optimize the application energy profile.

STLINK-V3PWR adds further strength to the energy-conscious embedded developer’s toolkit alongside the STM32 Power shield (X-NUCLEO-LPM01A), a programmable power supply source that provides dynamic current measurement from 100nA to 50mA. It’s typically used to analyze applications running on ultra-low-power STM32 MCUs. In addition, the energy meter of the STM32L562E-DK Discovery kit intermediate board measures dynamic current from 300nA to 150mA. STM32CubeMonitor-Power acquires power measurements through any of these devices and allows data rendering in real-time as well as updating of acquisition parameters.

As a programming and debug probe, STLINK-V3PWR also features single-wire debug (JTAG/SWD) interfaces to communicate with the STM32 MCU on the application board. There is also a Virtual COM port interface and a multi-path bridge allowing the host PC to communicate with the target microcontroller through a SPI/UART/I2C/CAN/GPIO communication to facilitate firmware update as well as power measurement tests in the field.
