ST72F561R9TA datasheet by STMicroelectronics

ST72F561R9TA Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the ST72F561R9TA?
  The ST72F561R9TA can operate from -40°C to +85°C, but it's recommended to operate within -20°C to +70°C for optimal performance.
• How do I configure the clock source for the ST72F561R9TA?
  The clock source can be configured using the Clock Control Register (CKCU). You can choose between the internal RC oscillator, external crystal oscillator, or external clock source. Refer to the ST72F561R9TA user manual for detailed configuration steps.
• What is the maximum current consumption of the ST72F561R9TA?
  The maximum current consumption of the ST72F561R9TA depends on the operating frequency and voltage. At 16 MHz and 3.3V, the typical current consumption is around 10 mA. However, this can increase to around 20 mA at 32 MHz and 3.3V. Refer to the datasheet for more detailed information.
• How do I implement a watchdog timer on the ST72F561R9TA?
  The ST72F561R9TA has a built-in watchdog timer that can be enabled and configured using the Watchdog Timer Control Register (WDTC). You can set the watchdog timer period and enable it to reset the microcontroller in case of a software fault.
• Can I use the ST72F561R9TA with a 5V power supply?
  No, the ST72F561R9TA is designed to operate at a maximum voltage of 3.6V. Operating the device at 5V can cause damage or malfunction. Ensure you use a suitable voltage regulator or power supply to provide a stable 3.3V or lower voltage to the microcontroller.
