STM32L412 in STM32 Family
The STM32L412 sub-family from STMicroelectronics is an entry-level ultra-low-power microcontroller series based on the high-performance ARM Cortex-M4 32-bit RISC core. Operating at frequencies up to 80 MHz, these MCUs balance computational power with extreme energy efficiency. They are designed for developers who require the digital signal processing capabilities and floating-point unit of the Cortex-M4 core while maintaining a minimal power footprint in cost-sensitive, battery-operated embedded systems.
