Product details

Overview

NUCLEO-L4R5ZI-P from STMicroelectronics is a 144-pin Nucleo-144 development board built around the STM32L4R5ZIT6PU Arm® Cortex®-M4 microcontroller featuring 2 MB Flash, 640 KB SRAM, and integrated external SMPS for ultra-low-power operation. It integrates ST-LINK/V2-1 debugger/programmer, USB OTG FS, three user LEDs, two push-buttons, and dual expansion headers (ST Zio + ST morpho) for rapid prototyping of IoT sensor nodes, portable medical devices, and battery-powered industrial controllers.

For engineers reviewing the NUCLEO-L4R5ZI-P datasheet, NUCLEO-L4R5ZI-P pinout, NUCLEO-L4R5ZI-P application, or NUCLEO-L4R5ZI-P equivalent, key selection criteria include on-board SMPS support, LQFP144 MCU package compatibility, ST-LINK/V2-1 virtual COM port functionality, and Arduino Uno V3–compatible ST Zio connector layout for shield interoperability.

Technical Context

The board implements a split architecture: one side hosts the ST-LINK/V2-1 debugger (STM32F103CBT6), the other hosts the target STM32L4R5ZIT6PU MCU in LQFP144. Power routing supports three sources - USB VBUS, external VIN (7–12 V), or ST-LINK's 5 V - with JP6 selecting the active source and SB100/SB102 configuring SMPS enablement.

Hardware block integration includes dedicated SWD debug interface (CN5), USB Micro-AB (CN1) supporting composite device enumeration (mass storage + VCP + debug), and dual high-density expansion headers exposing all MCU GPIOs, ADC channels, timers, and communication peripherals including LPUART1, USB FS OTG, and I²C/SPI/I²S.

Key Specifications

FAQ

Does NUCLEO-L4R5ZI-P support programming external STM32 targets?

Yes. The onboard ST-LINK/V2-1 can program and debug external STM32 devices via the SWD interface using CN5 (SWD connector) or routed SWD signals (SWCLK, SWDIO, NRST) on the ST morpho header (CN11 pins 15, 13, 14). Voltage level matching (3.3 V I/O) must be ensured between the Nucleo board and the target.

What is the purpose of the SMPS on the '-P' variant?

The external SMPS (switched-mode power supply) replaces the internal LDO to generate the MCU's Vcore supply from an external 7–12 V input, reducing typical Run-mode current consumption by up to 40% compared to non-SMPS variants - critical for battery-operated applications requiring multi-week runtime.

Can the ST-LINK/V2-1 on NUCLEO-L4R5ZI-P be updated?

Yes. ST-LINK/V2-1 firmware is upgradable via STM32CubeProgrammer or ST's dedicated ST-LINK Upgrade tool. Updates add support for newer STM32 families, improve debug stability, and enable enhanced power measurement features when JP5 (IDD) is configured for current sensing.

Is the NUCLEO-L4R5ZI-P compatible with Arduino shields?

Yes. The ST Zio connector is mechanically and electrically compatible with Arduino Uno R3 pinout, providing 5 V-tolerant digital I/O, analog inputs, PWM, I²C, SPI, and UART. Shield compatibility requires software-level peripheral mapping alignment - no hardware modification needed for standard shields.
