Overview

The STM32L072RZT6 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, 20KB of RAM, and 6KB of integrated EEPROM, specifically designed to minimize power consumption in battery-operated devices.

Why Choose This Part

The device offers a wide supply voltage range from 1.65V to 3.6V and consumes as little as 93 uA/MHz in run mode. It includes hardware-based ECC for Flash memory and a True Random Number Generator (RNG) for secure communication protocols.

Applications

Battery-Powered IoT Sensors
Utilizes ultra-low-power modes and 0.29uA standby current for long-term remote monitoring.
Portable Medical Devices
Leverages the 12-bit ADC and integrated EEPROM for logging patient data in handheld diagnostic tools.
Smart Utility Meters
Ideal for gas and water meters requiring a decade of battery life and secure firmware updates via 192KB Flash.
USB Peripherals
Integrates a USB 2.0 crystal-less interface for low-cost, low-power PC connectivity.
