Product details

Overview

NUCLEO-L476RG from STMicroelectronics is an STM32 Nucleo-64 development board built around the STM32L476RGT6 ultra-low-power Arm® Cortex®-M4 microcontroller (100 MHz, 1 MB Flash, 128 KB RAM, LQFP64 package), featuring integrated ST-LINK/V2-1 debugger/programmer via USB Mini-B, Arduino Uno V3 and ST morpho expansion headers, and a 32.768 kHz crystal for real-time clock applications in battery-powered IoT sensor nodes.

For engineers reviewing the NUCLEO-L476RG datasheet, NUCLEO-L476RG pinout, NUCLEO-L476RG application, or NUCLEO-L476RG equivalent, this board supports rapid prototyping of energy-constrained embedded systems requiring USB device connectivity, analog signal acquisition (12-bit ADC, DAC), low-power timer peripherals, and secure firmware updates via its on-chip cryptographic accelerators and trusted boot features.

Technical Context

The NUCLEO-L476RG implements the STM32L4+ series architecture with dual-bank Flash for seamless firmware updates, flexible power management (Run, Stop, Standby modes down to 200 nA), and hardware-accelerated AES-128/256 and SHA-256 for secure boot and data encryption. It integrates a high-precision 16-bit timer with quadrature encoder interface and three ultra-low-power comparators.

Its ST-LINK/V2-1 subsystem provides mass storage programming, Virtual COM port, and SWD debugging over a single USB Mini-B connection - no external probe required. The board's ARDUINO® Uno V3 and ST morpho headers expose all 50 GPIOs, including 16 analog inputs, 21 PWM-capable pins, and dedicated USB, CAN, and SPI signals.

FAQ

Does NUCLEO-L476RG support USB host functionality?

No. The board implements only USB Full-Speed device mode via the STM32L476RGT6's integrated USB peripheral. It lacks external USB PHY or VBUS sensing circuitry required for host or OTG operation. Developers requiring host capability must use external USB host shields or select boards like NUCLEO-F446RE with dual-role support.

Can the onboard ST-LINK/V2-1 program external STM32 targets?

Yes. The ST-LINK/V2-1 can be used as an external debugger by disconnecting the SB12/SB13 solder bridges (CN2 header), enabling SWD connection to external STM32 MCUs. Voltage translation is limited to 1.65–3.3 V logic levels, and no 5 V tolerance is provided.

Is the 32.768 kHz crystal mandatory for RTC operation?

Yes. The LSE crystal is soldered and required for accurate RTC timekeeping and calendar functions. While the MCU supports LSE bypass mode or internal LSI, only the external crystal delivers ±20 ppm accuracy needed for timestamping and wake-up scheduling in low-power modes.

What IDEs are officially supported for NUCLEO-L476RG firmware development?

STMicroelectronics officially supports STM32CubeIDE (free, cross-platform), Keil MDK-ARM (Windows-only, free license for Cortex-M0/M0+/M3/M4), and IAR Embedded Workbench for Arm (commercial). All integrate STM32CubeMX for pin configuration, clock tree setup, and middleware stack generation.
