NUCLEO-L452RE-P
Overview
The NUCLEO-L452RE-P is a Nucleo-64 development board featuring the STM32L452RET6P microcontroller, an ultra-low-power Arm Cortex-M4 core running up to 80 MHz. This specific variant includes an external SMPS (Switched-Mode Power Supply) to significantly reduce power consumption in Run mode. The board provides 512 KB of Flash and 160 KB of RAM, making it suitable for prototyping high-efficiency battery-operated applications.
Why Choose This Part
The inclusion of an onboard external SMPS allows for drastically lower power consumption in Run mode compared to standard LDO-only variants. It maintains hardware compatibility with Arduino Uno V3 and ST morpho headers for extensive peripheral expansion. The integrated ST-LINK/V2-1 debugger simplifies the development workflow by providing a virtual COM port and drag-and-drop programming.
Applications
Key Specifications
Getting Started
Connect the board to a PC via a USB Micro-B cable to power the device and access the integrated ST-LINK debugger. Use the STM32CubeIDE or Keil MDK for development, and leverage the STM32CubeL4 software package for HAL and low-layer drivers. The board's SMPS functionality can be evaluated by monitoring current draw through the dedicated jumpers provided on the PCB.
Also Consider
STMicroelectronics
- Standard version without the external SMPS, suitable if the specific power optimization of the SMPS is not required for your design.
STMicroelectronics
- Offers a larger 1 MB Flash memory and more peripherals while remaining in the ultra-low-power STM32L4 family.
