Overview

The STM32L071CZT6TR is an ultra-low-power microcontroller based on the high-performance Arm Cortex-M0+ 32-bit RISC core operating at 32 MHz. It features 192 Kbytes of Flash memory, 20 Kbytes of RAM, and is designed specifically for battery-operated applications requiring high efficiency and low current consumption.

Why Choose This Part

This MCU offers multiple power-saving modes, including a 0.29 microamp Standby mode and a 0.23 microamp Shutdown mode. It includes a hardware parity check for RAM to enhance system reliability and provides a wide range of peripherals such as ADC, DAC, and numerous serial interfaces.

Applications

Battery-Powered Sensors
Ideal for remote environmental sensors or industrial monitoring nodes where long battery life is critical.
Utility Meters
Suited for gas and water meters that require high memory density for data logging and low standby power.
Wearable Devices
The small footprint and power efficiency make it a fit for health trackers and smart watches.
Smart Home Nodes
Controls connected lighting or HVAC sensors with minimal thermal output and power draw.

Getting Started

Developers can utilize the STM32CubeL0 software package and the STM32CubeMX tool for clock configuration and peripheral initialization. The part is fully compatible with the Keil MDK, IAR Embedded Workbench, and GCC-based IDEs like STM32CubeIDE. For hardware evaluation, the NUCLEO-L073RZ provides a compatible development path for the L0 series.
