STMicroelectronics Introduces STM32 Programmable Debugger with Extended Power Range
STLINK-V3PWR is a new in-circuit debug programmer from STMicroelectronics that can accurately measure the power consumption of applications running on any STM32 microcontroller (MCU).
The product's wide dynamic range handles power-sensitive developments such as IoT and wireless applications, and can measure current values from nanoamps to 500mA with ±0.5% accuracy. 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.
The 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, Arm® Keil® development tools and the IAR integrated development environment (IDE) support the product, enabling simultaneous code execution and energy measurement to optimize the application energy map.
"Ultra-low-power microcontroller applications rely on energy harvesting or battery operation for years, and small design mistakes can cause unexpected power consumption problems," said Reinhard Keil, senior director of embedded technology at Arm. The new STLINK-V3PWR The debug programmer enables developers to analyze power consumption with the Keil MDK. The µVision debugger correlates program events with power consumption and provides analysis results that help developers identify potential design errors and double the battery life."
Anders Holmberg, CTO of IAR Corporation, added: "IAR Embedded Workbench for Arm fully supports the STLINK-V3PWR debug programmer, enabling developers to access accurate, repeatable and high-resolution power analysis results faster and easier .It will certainly help the next generation of ultra-low power and ultra-efficient smart IoT devices to achieve greater energy saving and energy efficiency, while greatly speeding up the time-to-market of new products."
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 from 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 measurements through any of these three tools, presents the 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 bridge, allowing the host controller to use SPI The /UART/I2C/CAN/GPIO interface communicates with the target microcontroller to facilitate firmware updates and on-site power measurement tests.
