STM32L4Q5CGU6P - STMicroelectronics

STM32L4Q5CGU6P Frequently Asked Questions (FAQs)

• What is the maximum clock frequency of the STM32L4Q5CGU6P?
  The maximum clock frequency of the STM32L4Q5CGU6P is 120 MHz, but it can be overclocked to 140 MHz with a reduced voltage range.
• How do I configure the internal voltage regulator (VDDA) for optimal performance?
  To configure the internal voltage regulator (VDDA) for optimal performance, set the VOS (Voltage Output Scale) bits in the POWER_CSR1 register to select the desired voltage output (e.g., 1.8V, 2.5V, or 3.3V).
• What is the purpose of the BOOT0 and BOOT1 pins?
  The BOOT0 and BOOT1 pins are used to select the boot mode of the microcontroller. BOOT0 selects between the internal flash memory and an external memory, while BOOT1 selects between the internal flash memory and the system memory.
• How do I use the internal temperature sensor?
  To use the internal temperature sensor, enable the VBAT (Battery Voltage Monitoring) interface, and then read the temperature data from the VBAT register. The temperature data is represented as a 12-bit value, with a resolution of 0.06°C per LSB.
• What is the maximum current consumption of the STM32L4Q5CGU6P?
  The maximum current consumption of the STM32L4Q5CGU6P depends on the operating mode and frequency. In Run mode at 120 MHz, the maximum current consumption is approximately 350 mA. In Low-power run mode at 32 kHz, the maximum current consumption is approximately 20 μA.
