STM32L471 in STM32 Family
The STM32L471 sub-family from STMicroelectronics is a high-performance, ultra-low-power microcontroller line based on the Arm Cortex-M4 core with a Floating Point Unit (FPU). Operating at frequencies up to 80 MHz, these devices bridge the gap between low energy consumption and computational power. They are engineered for power-constrained applications requiring digital signal processing and high-precision analog integration, featuring a dedicated Digital Filter for Sigma-Delta Modulators (DFSDM) and extensive power management modes.
Variants in This Sub-Family
Variants within the STM32L471 sub-family are primarily distinguished by their Flash memory density, ranging from 256 KB to 1 MB, and package pin counts from LQFP64 to UFBGA144. While all members feature the core Cortex-M4 architecture and DFSDM, certain packages provide additional GPIO accessibility and peripheral multiplexing options to suit different PCB footprint requirements and system complexities.
