Overview

The STM32L476ZET6 is an ultra-low-power microcontroller based on the ARM Cortex-M4 core running at 80MHz with a floating-point unit (FPU). It is designed to bridge the gap between high-performance processing and extreme power efficiency, featuring 512KB of Flash memory and a dedicated segment LCD controller.

Why Choose This Part

The inclusion of the Adaptive Real-Time (ART) Accelerator allows zero-wait-state execution from Flash, maintaining high performance while consuming only 10.2mA at 80MHz. Its flexible power control architecture includes a shutdown mode that draws as little as 30nA, making it suitable for applications that spend most of their time in a deep sleep state.

Applications

Battery-Powered Medical Devices
Ideal for portable glucose meters or pulse oximeters that require high-precision analog-to-digital conversion and long battery life.
Industrial Sensor Nodes
Utilizes low-power run and sleep modes to monitor environmental data over long periods using the integrated 24-channel ADC.
Smart Utility Meters
Leverages the internal RTC, hardware calendar, and LCD driver for standalone gas or water metering applications.
Human-Machine Interface (HMI)
Supports capacitive touch sensing and rotary sensors for modern appliance control panels.
