Overview

The STM32L072VBT6 is an ultra-low-power 32-bit microcontroller based on the Arm Cortex-M0+ core, designed for power-constrained applications requiring a balance of processing and peripheral integration. Operating at up to 32MHz, it features 128KB of Flash memory and a specialized 6KB EEPROM for non-volatile data storage. The device is characterized by its wide supply voltage range from 1.65V to 3.6V and a variety of low-power modes to extend battery life.

Why Choose This Part

This MCU provides a highly efficient performance-to-power ratio with a Cortex-M0+ core and dedicated hardware oversampling to improve ADC resolution. The inclusion of 6KB of true EEPROM simplifies firmware by eliminating the need for complex Flash emulation for data storage.

Applications

Battery-Powered IoT Nodes
Utilizes the 0.85uA standby current and integrated USB 2.0 interface for efficient, compact remote sensors.
Industrial Pulse Counters
Leverages hardware oversampling and multiple timers to monitor sensor inputs while maintaining a low power profile.
Portable Medical Devices
The integrated 12-bit ADC, DAC, and true RNG support secure, high-precision biometric data acquisition.
Smart Utility Meters
Takes advantage of the 6KB EEPROM for frequent data logging and the 100-pin LQFP package for high I/O requirements.
