STM32U031K4U6 Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the STM32U031K4U6 is 32 MHz, which can be achieved using an external crystal oscillator or an internal high-speed internal oscillator (HSI).
  • The STM32U031K4U6 has 16 KB of flash memory, which is divided into two banks: a 12 KB main flash memory and a 4 KB system flash memory.
  • No, the STM32U031K4U6 is a 3.6V device and should not be operated at 5V. Operating the device at 5V can cause damage or permanent failure.
  • The power consumption of the STM32U031K4U6 in low-power mode (Stop mode) is typically around 2.5 μA/MHz, depending on the clock frequency and peripheral usage.
  • No, the STM32U031K4U6 does not have a built-in USB interface. However, it has a USB FS Device peripheral that can be used to implement a USB device interface with an external USB transceiver.
