What are the key features of STM32L471VE?
- Ultra-low-power Cortex-M4 core at 80 MHz with FPU achieving down to 36 µA/MHz in Run mode
- DFSDM digital filter supporting up to 8 channels for direct sigma-delta ADC or PDM microphone interfaces
- 512 KB dual-bank Flash with read-while-write capability for OTA firmware update without halting execution
- Flexible SmartRun domain enabling autonomous peripheral operation while the CPU stays in Stop mode
What is STM32L471VE used for?
The STM32L471VE is ideal for industrial handheld devices, medical portable monitors, and smart metering applications where long battery life must coexist with real-time DSP processing. Its DFSDM block enables direct connection to external sigma-delta ADCs or digital microphones, making it suitable for audio acquisition and vibration analysis in condition-monitoring systems. Energy harvesting IoT nodes also benefit from the chip's sub-microampere Standby mode and the flexible autonomous operating domain.

Frequently Asked Questions
What is the Flash and SRAM size of STM32L471VE, and does it support dual-bank operation?
STM32L471VE offers 512 KB of Flash organized in 2 banks of 256 KB each, plus 128 KB of SRAM. Dual-bank operation enables read-while-write so firmware updates via OTA can proceed while the application continues running without interruption.
Which control applications can run STM32L471VE at 80 MHz from a 1.8V to 3.6V supply rail?
Industrial sensor hubs, motor position encoders, and smart grid metering units commonly use STM32L471VE at 80 MHz with a 3.3V rail. The Cortex-M4 FPU handles floating-point PID loops, while the 80 MHz clock sustains real-time control cycles under 1 µs.
How many DFSDM channels does STM32L471VE provide, and what sigma-delta or audio sources can it handle?
STM32L471VE integrates DFSDM with up to 8 channels and 4 filter blocks, supporting external sigma-delta ADCs and PDM digital microphones. Oversampling ratios up to 256 provide effective resolutions exceeding 16-bit for precision audio or vibration measurements.
When is STM32L471VE a better choice than STM32L476VG for power-critical portable designs?
STM32L471VE suits designs where 512 KB Flash suffices and cost or power savings outweigh the need for STM32L476VG's DAC channels and LCD driver. Both share the same 100-pin LQFP-100 footprint, so migrating between them requires only firmware changes, not PCB redesign.
