Overview

The STM32L412K8U6 is an ultra-low-power microcontroller based on the high-performance Arm Cortex-M4 32-bit RISC core operating at up to 80 MHz. It features 64KB of Flash memory and 40KB of SRAM, incorporating an FPU and DSP instructions for efficient signal processing. This MCU is designed for power-sensitive applications, utilizing FlexPowerControl to optimize power consumption across multiple low-power modes.

Why Choose This Part

It offers an exceptional balance between performance and power consumption, drawing as little as 28 microAmps per MHz in run mode. The inclusion of the ART Accelerator allows for 0-wait-state execution from Flash, while the variety of low-power modes down to 16nA in shutdown provides extreme flexibility for energy management.

Applications

Battery-Powered IoT Sensors
Ideal for remote monitoring devices that require long battery life and periodic data processing using the Batch Acquisition Mode (BAM).
Wearable Technology
The small 5x5mm UFQFPN32 package and integrated capacitive sensing channels make it suitable for compact user interfaces and health trackers.
Industrial Field Instruments
Provides reliable performance in harsh environments with 5V-tolerant I/Os and integrated safety features like the Brown-out Reset (BOR).
USB Peripherals
The integrated USB support and low-power run modes enable the development of energy-efficient PC accessories and mobile dongles.
