ATMEGA808-MU Frequently Asked Questions (FAQs)

  • The ATMEGA808-MU can operate at a maximum clock frequency of 20 MHz, but it is recommended to use a clock frequency of 16 MHz or lower for optimal performance and to ensure that the device operates within its specifications.
  • To configure the ATMEGA808-MU to use an external crystal oscillator, you need to connect the crystal to the XTAL1 and XTAL2 pins, and then configure the CKSEL fuses to select the external crystal oscillator as the clock source. You can do this using the AVRDUDE software or by writing a program to configure the fuses.
  • The maximum amount of current that can be drawn from the ATMEGA808-MU's I/O pins is 40 mA per pin, but it is recommended to limit the current to 20 mA per pin to ensure that the device operates within its specifications.
  • To use the ATMEGA808-MU's built-in UART, you need to configure the UART registers to set the baud rate, data bits, parity, and stop bits. You can then use the UART to transmit and receive data using the USART0_TX and USART0_RX pins.
  • Yes, the ATMEGA808-MU can be used in a 3.3V system, but it is recommended to use a voltage regulator to ensure that the device operates within its specifications. The device can operate at a voltage range of 1.8V to 5.5V, but it is recommended to use a voltage of 3.3V or higher for optimal performance.
