Overview

The STM32L476VET6 is an ultra-low-power microcontroller based on the ARM Cortex-M4 core with a Floating Point Unit (FPU), running at speeds up to 80MHz. This device balances high performance with exceptional energy efficiency, featuring 512KB of Flash memory, 128KB of RAM, and an integrated LCD controller for driving segmented displays.

Why Choose This Part

The inclusion of the ART Accelerator allows zero-wait-state execution from Flash, while the FlexPowerControl architecture provides granular control over power consumption, reaching shutdown currents as low as 64.1nA. It offers high analog integration with three 12-bit ADCs and two 12-bit DACs, reducing the need for external components in precision sensing applications.

Applications

Battery-Powered Medical Devices
Ideal for portable glucose monitors and pulse oximeters that require high-precision 12-bit ADC sampling and long battery life.
Smart Utility Meters
Used in water and gas meters where the integrated LCD driver and low-power Stop modes enable decade-long operation on a single cell.
Industrial Sensor Nodes
Perfect for remote monitoring sites using the QSPI interface for external memory and multiple serial interfaces for sensor fusion.
Wearable Fitness Trackers
Leverages the 21-channel capacitive sensing and FPU for processing motion algorithms while maintaining a small power footprint.
