The STM32L471VET6 is an ARM Cortex-M4 microcontroller with an FPU from STMicroelectronics. This device operates at 80 MHz and has 512 KBytes of embedded Flash memory, along with DFSDM. One of the main features that makes it so suitable for ultra-low power applications is its low power consumption — it can run on as little as 0.9 mA/MHz in active mode and 0.8 µA/MHz in standby mode. It has a variety of features, such as 1.62 Volt internal voltage regulator, temperature range of -40 °C to +105 °C, several I/O lines, 2 ADCs, USB Full-speed device, and one window watchdog for safety. The STM32L471VET6 is suitable for a wide range of applications – from industrial to medical and portable, providing a secure and efficient implementation.
