ST72F521R9T3 Frequently Asked Questions (FAQs)

  • The maximum clock frequency that can be used with the internal oscillator is 16 MHz. However, it's recommended to use a clock frequency of 12 MHz or lower to ensure reliable operation.
  • The watchdog timer can be configured using the WWDG_CR register. Set the WWDG_CR[WDGA] bit to enable the watchdog timer, and then set the WWDG_CR[7:0] bits to set the timeout period.
  • The maximum current that can be sourced or sunk by the GPIO pins is 20 mA. However, it's recommended to limit the current to 10 mA or less to ensure reliable operation.
  • To use the ADC with an external reference voltage, connect the external reference voltage to the VREF+ pin, and set the ADC_CSR[REFSEL] bit to 1. Then, configure the ADC_CSR register to select the external reference voltage as the ADC reference voltage.
  • The minimum voltage range for the VDD power supply is 2.4 V, and the maximum voltage range is 5.5 V.
