ATXMEGA64A3U-AU Frequently Asked Questions (FAQs)

  • The maximum clock frequency for the ATXMEGA64A3U-AU is 32 MHz, but it can be overclocked to 40 MHz with some limitations.
  • The clock source can be configured using the CLKSEL fuse bits in the FUSEBYTE register. The clock source can be set to internal RC oscillator, external crystal oscillator, or external clock source.
  • The maximum current that can be sourced or sunk by the I/O pins is 20 mA per pin, with a total current limit of 200 mA for all I/O pins combined.
  • The UART can be configured using the USARTn.CTRLA and USARTn.CTRLB registers. The UART can operate in asynchronous mode, synchronous mode, or IrDA mode.
  • The JTAG interface is used for debugging and programming the device. It allows for boundary scan, debugging, and flash programming.
