ST10F273Z4Q3 datasheet by STMicroelectronics

ST10F273Z4Q3 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 72 MHz. However, it's recommended to use a clock frequency of 64 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 mode with a sampling time of at least 1.5 cycles.
• 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.
• How do I implement a watchdog timer with this microcontroller?
  The ST10F273Z4Q3 has a built-in watchdog timer that can be enabled and configured using the WWDG registers. The watchdog timer can be set to reset the microcontroller if it doesn't receive a refresh signal within a specified time period.
• Can I use the USB interface to communicate with a PC?
  Yes, the ST10F273Z4Q3 has a built-in USB 2.0 full-speed interface that can be used to communicate with a PC. The microcontroller can operate as a USB device, and the USB interface can be configured using the USB registers.
