ATMEGA16A-MU Frequently Asked Questions (FAQs)

  • The maximum clock frequency for the ATMEGA16A-MU is 16 MHz.
  • To configure the USART for asynchronous communication, set the USART Control and Status Register A (UCSRnA) to enable the transmitter and receiver, and set the baud rate using the USART Baud Rate Register (UBRRn).
  • Yes, the ATMEGA16A-MU can operate with a 3.3V power supply, but the maximum clock frequency will be limited to 12 MHz.
  • To use the internal oscillator as the clock source, set the Clock Source Select (CKSEL) fuses to select the internal oscillator, and set the Clock Prescaler (CLKPR) to divide the clock frequency as needed.
  • The maximum current that can be sourced or sunk by the I/O pins is 40 mA.
