STM32L471RET3 Frequently Asked Questions (FAQs)

  • The STM32L471RET3 can operate from -40°C to 85°C (industrial grade) or -40°C to 125°C (extended grade), depending on the specific part number and grade.
  • The internal clock source can be configured using the Clock Security System (CSS) and the Power Management Unit (PMU). The HSE (High-Speed External) clock, LSE (Low-Speed External) clock, HSI (High-Speed Internal) clock, and LSI (Low-Speed Internal) clock can be used as clock sources. The clock configuration is done using the RCC (Reset and Clock Control) registers.
  • The maximum current consumption of the STM32L471RET3 depends on the operating frequency, voltage, and peripherals used. According to the datasheet, the typical current consumption is around 350 μA/MHz in Run mode and 2.5 μA in Sleep mode, but this can vary depending on the specific application and usage.
  • The STM32L471RET3 has several low-power modes, including Sleep mode, Stop mode, and Standby mode. These modes can be entered using the PWR (Power) registers and the Cortex-M4 processor's sleep modes. The low-power modes can be used to reduce power consumption and extend battery life in battery-powered applications.
  • The maximum frequency of the STM32L471RET3 is 80 MHz, but it can be overclocked to 100 MHz using the internal PLL (Phase-Locked Loop) multiplier.
