ST72C216G1B6 datasheet by STMicroelectronics

ST72C216G1B6 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for ST72C216G1B6?
  The recommended operating voltage range for ST72C216G1B6 is 4.5V to 5.5V, with a typical voltage of 5V.
• How do I handle the reset pin (RST) during power-up and power-down?
  The reset pin (RST) should be tied to VCC through a pull-up resistor (e.g., 10kΩ) and a capacitor (e.g., 100nF) to ground to ensure proper reset during power-up and power-down.
• What is the maximum clock frequency that can be used with ST72C216G1B6?
  The maximum clock frequency that can be used with ST72C216G1B6 is 16 MHz, but it can be operated at lower frequencies depending on the application requirements.
• How do I configure the oscillator circuit for ST72C216G1B6?
  The oscillator circuit can be configured by connecting a crystal oscillator between the OSC1 and OSC2 pins, with a load capacitor (e.g., 22pF) connected between each pin and ground.
• What is the purpose of the watchdog timer (WDT) in ST72C216G1B6?
  The watchdog timer (WDT) is used to reset the microcontroller in case of a software or hardware failure, ensuring that the system remains operational and preventing it from getting stuck in an infinite loop.
