The AT32AP CPU core is a high-performance implementation featuring a 7-stage pipeline, separate instruction- and data caches, and a MMU. For more information, please see the "AVR32 AP Technical Reference": http://www.atmel.com/dyn/resources/prod_documents/doc32001.pdf In addition to this, the AT32AP7000 chip comes with a large set of integrated peripherals, many of which are shared with the AT91 series of ARM-based microcontrollers from Atmel.
