The STM32L412CBU6P from STMicroelectronics is an ultra-low-power 32-bit MCU built around the ARM Cortex-M4 core. It delivers 80MHz performance with 128KB flash and 40KB SRAM, operating from 1.71V to 3.6V. The 48-UFQFN package is ideal for space-constrained designs. It includes DMA, PWM, and brown-out detection, with an external SMPS option for enhanced efficiency in active modes.
- Ultra-low power consumption: Multiple low-power modes and 1.71V operation extend battery life in portable devices.
- High performance per watt: The 80MHz Cortex-M4 with FPU handles DSP tasks efficiently without excessive energy draw.
- Compact footprint: The 48-UFQFN package reduces board area for miniaturized products.
- Rich analog and digital peripherals: DMA, PWM, and brown-out reset simplify system design and improve reliability.
Battery-Powered IoT Sensors
The 1.71V minimum supply and multiple low-power modes make it ideal for long-life environmental or asset-tracking sensors.
Portable Medical Devices
The 80MHz Cortex-M4 with DSP instructions handles signal processing for glucose meters or pulse oximeters while maintaining low power draw.
Industrial Control Panels
With PWM and DMA, it can drive HMI interfaces and motor control loops in 24V industrial systems with an external regulator.
Smart Home Hubs
128KB flash supports complex protocol stacks (Zigbee, Thread) while the UFQFN package saves PCB space in compact wall modules.
Wearable Fitness Trackers
The 40KB SRAM buffers sensor data, and the brown-out detector ensures reliable operation during battery voltage drops.
Energy Harvesting Nodes
Its ultra-low-power standby modes and wide voltage range allow direct operation from solar cells or TEG harvesters with minimal power conditioning.
