Source measurement unit (SMU) and debugger/programmer for
STM32 microcontrollers
Introduction
STLINK-V3PWR
is a two-in-one standalone debugger probe and a source measurement unit (SMU) designed to synchronize
code execution with a power consumption of STM32 applications in real time. This tool is specifically adapted for power
consumption optimization (patent pending).
STLINK-V3PWR can be used as a standalone source measurement unit to supply power and measure the current consumption
of the target application. The product keeps the output voltage constant during fast current transient from very low current to
high current.
STLINK-V3PWR is also a standalone debugging and programming probe for STM32 microcontrollers. The product embeds a
multi-path bridge interface with an integrated level shifter to adapt to the target application I/Os voltage.
®
STLINK-V3PWR USB Type-C
connector allows data communication with the host PC and sinks up to 5 V/3 A to supply both
the probe and the target application, via the SMU and the auxiliary output.
