Overview

The STM32L051R8T6 is an ultra-low-power microcontroller based on the high-performance Arm Cortex-M0+ 32-bit RISC core operating at 32 MHz. It features 64 Kbytes of Flash memory, 8 Kbytes of RAM, and a wide range of enhanced I/Os and peripherals designed for energy-sensitive applications.

Why Choose This Part

The part excels with a highly efficient power-to-performance ratio and multiple low-power modes that allow designers to optimize current consumption. It includes a hardware RTC and an internal 12-bit ADC capable of operating at very low voltages, which simplifies power supply design for mobile electronics.

Applications

Battery-Operated Sensors
Ideal for remote environmental sensors where long battery life is critical due to its low power consumption in standby and stop modes.
Smart Utility Meters
Utilizes the built-in RTC and low-power peripherals to maintain timekeeping and monitoring with minimal energy draw.
Wearable Devices
The small footprint and efficient processing make it suitable for fitness trackers and basic health monitoring equipment.
Industrial Alarms
Used in smoke and gas detectors that require years of operation from a single primary cell battery.

Getting Started

Begin development using the STM32CubeL0 software package which includes HAL and LL drivers. The NUCLEO-L053R8 development board provides a compatible hardware environment for prototyping, and code can be compiled using Keil MDK, IAR EWARM, or STM32CubeIDE via an ST-LINK debugger.
