This tool is used for field upgrades of Atmel 8-bit AVR microcontrollers with ISP or PDI interfaces. Using the included AVR Studio® software, designers can program tinyAVR and megaAVR devices using the ISP Interface, tinyAVR devices using the TPI interface, and AVR XMEGA devices using the PDI Interface. The AVR Studio online-help contains the most current information and a complete list of supported devices.
