Overview

The STM32L072VZT6 is an ultra-low-power 32-bit microcontroller based on the ARM Cortex-M0+ core, operating at frequencies up to 32MHz. It features 192KB of Flash memory and 6KB of integrated EEPROM, specifically designed to minimize power consumption in battery-operated applications. With a wide operating voltage range of 1.65V to 3.6V and a shutdown current of approximately 0.29uA, it provides an efficient balance of performance and power conservation.

Why Choose This Part

The device excels in power management, offering a high-efficiency Cortex-M0+ core and dedicated hardware for CRC calculation and firewall protection. Its inclusion of 6KB true EEPROM reduces the need for external storage components, while the 84 I/O pins in the 100-LQFP package provide extensive connectivity for complex peripherals. Engineers benefit from 5V-tolerant I/Os and a True Random Number Generator for secure communication tasks.

Applications

Battery-Powered IoT Sensors
Utilizing the low-power sleep and standby modes to extend the life of remote environmental or industrial monitoring nodes.
Smart Utility Meters
Leveraging the integrated RTC and LCD driver support for gas, water, or electricity metering systems requiring long-term reliability.
Wearable Medical Devices
Managing biometric data acquisition with the 12-bit ADC and hardware ECC while maintaining a small power footprint.
USB Peripherals
Implementing crystal-less USB 2.0 full-speed connectivity for low-power PC accessories or data loggers.

Getting Started

Start development using the STM32CubeL0 software package and the STM32CubeIDE for code generation and debugging. For hardware evaluation, the NUCLEO-L073RZ or a custom board featuring the 100-LQFP footprint can be used with an ST-LINK/V2 debugger. Utilize the STM32CubeMX tool to configure the low-power modes and clock tree specifically for the 32MHz maximum frequency.
