STM launches the STLINK-V3PRW debug probe for STM32 MCUs including power measurement. STMicroelectronics (STM) has announced a programming and debug probe for its STM32 line of Microcontrollers (MCUs).
The new probe is the STLINK-V3PWR which includes high-accuracy power measurement ability for ultra-low power measurements.
In a statement Arm’s Reinhard Keil is in support of STMicro’s latest debugging tool. “Ultra-low-power microcontroller applications use energy harvesting or run for years on batteries, however, small design errors can create unexpected power issues. The new STLINK-V3PWR probe enables power profiling with [Arm’s] Keil MDK. The µVision debugger can correlate program events with power consumption, providing analysis to help developers identify potential design errors and enabling multi-fold improvements to battery life.”
The functionality of the STLINK-V3PWR is what one would expect from a debug probe of this class, offering JTAG and Serial Wire Debug (SWD) connectivity to a specific MCU. There is a multi-path bridge to I2C, CAN, SPI, and UART. Additionally, there are the usual general-purpose I/O (GPIO) communication and the capability to flash firmware to a target device, when updates are ready.
The power profiling ability of the probe make is a unique debug and programming probe in the industry. STM is reporting that the probe can measure current values from microamps up to 500mA. The claim includes a high accuracy level of ∓0.5 percent. All the while providing up to 2A of power to a target system through a cable attachment.
“Full support for the STLINK-V3PWR probe within IAR Embedded Workbench for Arm allows developers faster and easier access to power analysis that is both accurate and repeatable, and with high resolution,” adds IAR’s Anders Holmberg of his company’s software, along with Arm Keil MDK, backing the launch of the probe.

“It is sure to help realize greater energy savings and efficiency gains in next-generation ultra-low-power and ultra-efficient smart, connected devices while also drastically accelerating their time to market.”
The pricing has been set at $93.10 which includes support for the STLINK-V3PWR and an in-house graphical power monitoring tool the STM32CubeMonPWR.
