STMicroelectronics launches STM32 programming debugger with extended power range, enabling next-generation ultra-low power applications
【Lansheng Technology Information】April 25, 2023, STLINK-V3PWR is a new in-circuit debug programmer from STMicroelectronics, which can accurately measure the application running on any STM32 microcontroller (MCU) power consumption.
The product's wide dynamic range can handle power-sensitive developments such as IoT and wireless applications, and can measure current values from nanoamps to 500mA with a measurement accuracy of ±0.5%. In addition, the product can provide up to 2A of current to the target system with a single USB cable, and developers do not need to connect a separate power supply to power the board.
STMicroelectronics' STM32CubeMonitor-Power graphics tool directly supports STLINK-V3PWR, which can display the power demand of the application in real time and analyze the impact of design changes on power consumption in order to improve energy efficiency. Additionally, the product is supported by Arm® Keil® development tools and the IAR integrated development environment (IDE), enabling simultaneous code execution and energy measurement to optimize the application energy map.
The STLINK-V3PWR further enhances STMicroelectronics' power-conscious embedded development kit offering. The STM32 Power shield (X-NUCLEO-LPM01A), is a programmable power supply with a dynamic current measurement range of 100nA to 50mA, typically used to analyze the power consumption of applications running on ultra-low-power STM32 MCUs. Additionally, the meter on the mid-board of the STM32L562E-DK Discovery Kit can measure dynamic currents from 300nA to 150mA. STM32CubeMonitor-Power obtains power measurement values through any of these three tools, presents data in real time, and updates the collected power parameters.
As a debug programmer for microcontrollers, STLINK-V3PWR communicates with the STM32 MCU on the application board through a single-wire debug (JTAG/SWD) interface, as well as a virtual COM port interface and a multipath The /UART/I2C/CAN/GPIO interface communicates with the target microcontroller to facilitate firmware updates and on-site power measurement tests.
