STR910FAM32X6 datasheet by STMicroelectronics

STR910FAM32X6 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the internal oscillator?
  The maximum clock frequency that can be used with the internal oscillator is 32 MHz. However, it's recommended to use a clock frequency of 24 MHz or lower to ensure reliable operation.
• How do I configure the ADC to achieve the highest accuracy?
  To achieve the highest accuracy with the ADC, it's recommended to use the internal voltage reference, enable the ADC calibration, and use the 12-bit conversion mode. Additionally, ensure that the analog input pins are not loaded and that the ADC clock frequency is set to 1.2 MHz or lower.
• What is the maximum current that can be sourced or sunk by the GPIO pins?
  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 and to prevent overheating.
• How do I implement a watchdog timer with the STR910FAM32X6?
  The STR910FAM32X6 has a built-in watchdog timer that can be enabled and configured using the WWDG registers. The watchdog timer can be set to trigger a system reset if the timer expires, and it can be fed by the system clock or an external clock source.
• What is the minimum and maximum voltage range for the VDD power supply?
  The minimum voltage range for the VDD power supply is 2.4 V, and the maximum voltage range is 3.6 V. It's recommended to use a voltage regulator or a power supply with a tight voltage tolerance to ensure reliable operation.
