What are the key features of STM32L431VCI3?
- Arm Cortex-M4 with FPU at 80 MHz delivering 100 DMIPS while consuming as low as 28 µA/MHz in run mode
- 256 KB Flash and 64 KB SRAM with ART Accelerator enabling code execution at full CPU speed from Flash
- Integrated 12-bit ADC, DAC, op-amp, and comparator supporting on-chip analog signal conditioning without external ICs
What is STM32L431VCI3 used for?
The STM32L431VCI3 is designed for ultra-low-power IoT edge nodes, wearable health monitors, and smart home sensors requiring floating-point computation with minimal battery drain. Its 28 µA/MHz active current and sub-microamp stop modes allow years of operation from a CR2032 coin cell in intermittent-wake applications such as temperature loggers and occupancy detectors. The integrated FPU and rich analog peripherals also suit audio processing and motor control in compact industrial portable instruments.

Frequently Asked Questions
What is the run-mode current consumption of the STM32L431VCI3 at 80 MHz, and how does that compare to sleep mode?
In run mode the STM32L431VCI3 consumes approximately 28 µA/MHz, equating to roughly 2.24 mA at its maximum 80 MHz clock. In stop mode 2 the current drops to about 0.4 µA, meaning a 250 mAh battery can sustain over 25 years of deep sleep with periodic 80 MHz wake cycles at 1 Hz duty.
How does the hardware FPU benefit DSP-intensive firmware on the STM32L431VCI3 compared to a Cortex-M0+ device?
The Cortex-M4 FPU executes single-precision floating-point multiply-accumulate in a single cycle, achieving 100 DMIPS at 80 MHz. A Cortex-M0+ at the same clock speed processes floating-point operations via software emulation, taking 20 to 200 cycles per operation. This difference matters in audio filters, PID loops, and sensor fusion algorithms that rely on heavy floating-point arithmetic.
Which package does the STM32L431VCI3 come in, and what pin count does it provide for peripheral connectivity?
The STM32L431VCI3 is housed in a UFBGA-100 package with 100 balls on a fine-pitch 0.5 mm grid. The 100-pin count provides access to multiple SPI, I2C, USART, SAI audio, USB, and CAN interfaces simultaneously, supporting multi-protocol designs in compact wearable and IoT gateway modules that require rich connectivity in a small PCB footprint.
