Overview

The STM32L476RGT6 is a high-performance ultra-low-power microcontroller based on the Arm Cortex-M4 core with a Floating Point Unit (FPU). It operates at up to 80MHz and features 1024KB of Flash memory and 128KB of RAM, balancing computational power with advanced power management. This device includes a built-in LCD controller and a wide array of digital and analog peripherals for demanding embedded applications.

Why Choose This Part

This MCU provides a significant performance boost over standard low-power chips by including an FPU and DSP instructions while maintaining a low sleep current of approximately 1.88uA. The ART Accelerator enhances execution speed from Flash, and the FlexPowerControl system allows fine-grained optimization of power consumption across various operating modes.

Applications

Battery-Powered Medical Devices
The ultra-low power consumption and integrated 12-bit ADCs make it suitable for portable glucose meters and heart rate monitors.
Smart Industrial Sensors
Utilizes the DSP instructions and FPU for local data processing and filtering in vibration or pressure monitoring systems.
Utility Metering
Integrated LCD driver (8x40 or 4x44) and low-power RTC are ideal for water and gas meters requiring long battery life.
Wearable Technology
Small 64-LQFP footprint combined with low-power run modes supports compact fitness trackers with complex UI requirements.

Getting Started

Development is best supported by the NUCLEO-L476RG board, which provides an integrated ST-LINK debugger and Arduino Uno V3 headers. Engineers should use the STM32CubeIDE for software development and STM32CubeMX for graphical clock and peripheral configuration. The part supports standard ARM JTAG/SWD interfaces for debugging and programming.
