ST72F321R6T6 Frequently Asked Questions (FAQs)

  • The maximum clock frequency that can be used with the internal oscillator is 16 MHz.
  • The watchdog timer can be configured using the WWDG_CR register. You need to set the WWDG_CR[WDGA] bit to enable the watchdog timer and set the timeout period using the WWDG_CR[0:6] bits.
  • The maximum current that can be sourced or sunk by the GPIO pins is 20 mA.
  • To use the ADC in scan mode, you need to configure the ADC_CSR register to select the channels to be converted, and then start the conversion by setting the ADC_CSR[ADON] bit. The ADC will then convert the selected channels sequentially.
  • The minimum voltage required for the device to operate is 2.4 V.
