Product details

Overview

NUCLEO-L452RE-P from STMicroelectronics is a 64-pin STM32L452RET6P-based Nucleo-64 development board featuring external SMPS support, USB Micro-B–connected ST-LINK/V2-1 debugger/programmer, ARDUINO® Uno V3 and ST morpho expansion headers, and 32.768 kHz crystal oscillator - designed for ultra-low-power IoT sensor node prototyping with real-time power optimization.

For engineers reviewing the NUCLEO-L452RE-P datasheet, NUCLEO-L452RE-P pinout, NUCLEO-L452RE-P application, or NUCLEO-L452RE-P equivalent, key selection considerations include external SMPS integration capability, LQFP64 package compatibility, 512 KB Flash/160 KB RAM microcontroller resources, and ST-LINK/V2-1 debug interface with mass storage and Virtual COM port modes.

Technical Context

The NUCLEO-L452RE-P implements the STM32L452RET6P MCU - an Arm Cortex-M4 core with FPU, operating up to 80 MHz, supporting multiple low-power modes (Stop 2, Standby), and integrating 512 KB Flash, 160 KB SRAM, and hardware crypto accelerators (AES, HASH, PKA). It uses an external SMPS controller to reduce Run-mode current consumption below 80 µA/MHz.

Board-level features include dual USB connectivity (ST-LINK via Micro-B, no user USB), ARDUINO® Uno V3 and ST morpho headers exposing all MCU I/Os, one user LED shared with ARDUINO®, one user push-button and one reset button, and a 32.768 kHz crystal for RTC accuracy - enabling rapid validation of power-sensitive firmware stacks.

Key Specifications

Parameter	Value and Actual Design Meaning
Target MCU	STM32L452RET6P - LQFP64, 512 KB Flash, 160 KB SRAM, Cortex-M4F @ 80 MHz
Power Architecture	External SMPS support - enables sub-80 µA/MHz Run-mode operation for battery-constrained designs
Debug Interface	On-board ST-LINK/V2-1 via USB Micro-B - provides mass storage programming, Virtual COM port, and SWD debugging

FAQ

Does NUCLEO-L452RE-P support USB device functionality for the target MCU?

No. Unlike NUCLEO-L452RE (non-P variant), the NUCLEO-L452RE-P lacks a user-facing USB connector - only the ST-LINK/V2-1 debugger is exposed via USB Micro-B. The STM32L452RET6P MCU itself supports USB Device FS, but no physical USB interface circuitry is implemented on this board for end-user application use.

What distinguishes NUCLEO-L452RE-P from NUCLEO-L452RE?

The "-P" suffix indicates external SMPS support - the NUCLEO-L452RE-P includes dedicated test points and routing for connecting an external DC-DC step-down converter to supply Vcore, reducing active-mode power vs. the standard NUCLEO-L452RE which uses linear regulation only. Both share identical MCU, pinout, and debug interface.

Can I use STM32CubeIDE to program and debug NUCLEO-L452RE-P out of the box?

Yes. STM32CubeIDE natively recognizes the on-board ST-LINK/V2-1 interface. No additional drivers are required on Windows 10/11, macOS, or Linux. The board appears as a mass storage device for drag-and-drop firmware updates and as a debug probe for full SWD-based breakpointing, register inspection, and real-time variable monitoring.

Is the 32.768 kHz crystal populated and functional on NUCLEO-L452RE-P?

Yes. The 32.768 kHz crystal oscillator is fully populated and soldered on the board, directly connected to the STM32L452RET6P's LSE pins. It enables precise RTC timekeeping, calendar functions, and low-power wake-up timers - verified in the board's UM2206 user manual and schematic.
