STM32L071CZU6TR - STMicroelectronics

STM32L071CZU6TR Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the STM32L071CZU6TR?
  The maximum operating temperature range for the STM32L071CZU6TR is -40°C to 85°C (industrial grade) and -40°C to 125°C (extended grade).
• How do I configure the internal clock source for the STM32L071CZU6TR?
  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.
• What is the maximum current consumption of the STM32L071CZU6TR?
  The maximum current consumption of the STM32L071CZU6TR depends on the operating mode and frequency. In Run mode, the maximum current consumption is around 350 μA/MHz at 32 MHz with all peripherals enabled. In Low Power Run mode, the maximum current consumption is around 150 μA/MHz at 32 MHz with all peripherals enabled.
• How do I use the low power modes of the STM32L071CZU6TR?
  The STM32L071CZU6TR has several low power modes, including Sleep mode, Stop mode, and Standby mode. These modes can be entered using the PWR (Power) registers. In Sleep mode, the CPU is stopped, but the peripherals remain active. In Stop mode, the CPU and peripherals are stopped, but the voltage regulator remains active. In Standby mode, the CPU, peripherals, and voltage regulator are stopped, and the device is in a very low power state.
• What is the purpose of the BOOT0 and BOOT1 pins on the STM32L071CZU6TR?
  The BOOT0 and BOOT1 pins are used to select the boot mode of the device. BOOT0 is used to select between the internal flash and the system memory as the boot source. BOOT1 is used to select between the internal flash and an external memory as the boot source.
