    Easiest to obtain a dongle to interface the PC to the micro. Try looking for an AVRISP.

    You can´t use I2C to program the chip unless you have a bootloader already inside. You need to use the ISP or JTAG pins to get any program into the flash memory.

    What kubeek said, except that the AVR XMEGA parts use JTAG or PDI, not ISP, which limits your selection of programming hardware considerably. The AVR Dragon is the cheapest option, I think, that will support the Xmega256D3. Other options are STK600, JTAGICE, or AVR ONE!. I believe that some of the USB parts actually do come with a USB bootloader, but this isn't one of them (since it doesn't have USB).
