The AVR32 is a 32-bit RISC microprocessor architecture designed by Atmel. The microprocessor architecture was designed by a handful of people educated at the Norwegian University of Science and Technology, including lead designer Øyvind Strøm, PhD and CPU architect Erik Renno, M.Sc in Atmel's Norwegian design center.

Most instructions are executed single-cycle. The multiply–accumulate unit is capable of performing a 32-bit * 16-bit + 48-bit arithmetic operation in two cycles (result latency), with an issue rate of one per cycle.

Any resemblance to the 8-bit AVR is only with respect to the design center (both architectures originated out of Atmel Norway, Trondheim) and some of the debug-tools.
