In summary, the USB enabled AVR XMEGA delivers a high data rate with minimal CPU load. Unique multi-packet buffering reduces the power consumption, takes less firmware overhead and frees up more time for other tasks. Including an internal RC oscillator for Full Speed communication reduces the BOM cost, gives fewer layout constraints and reduces the power consumption. To speed up development, a large number of fully compliant USB examples are made available. This reduces time to market for new products and makes it possible for those who are not USB experts to build a USB application. Using AVR Studio 5, developers can add any module to their application by navigating in the GUI. All dependencies are managed by AVR Studio 5.
