Atmel's AT91SAM Smart ARM-based [[microcontroller]]s are based on the [[32-bit]] [[RISC]] [[processor]] architecture from [[ARM]]. They include embedded [[Flash]] and [[SRAM]] [[memories]] together with a number of [[peripherals]] and standard communications/networking [[interface]]s. This qualifies them as [[system on chip]] devices.

External interfaces include [[USB]], [[CAN]], [[Ethernet]], [[SPI]], [[USART]] and [[ADC]]. A [[DMA]] controller provides direct communication channels between external interfaces and memories, increasing [[data]] throughput with minimal [[processor]] intervention.

Peripherals include counter/timers, [[power-on reset]] generators, [[voltage regulatorsregulator]]s and and advanced [[interrupt controller]]. This enhances the [[real time]] performance of the processor. A [[power management]] controller keeps power consumption to a minimum by powering down unused peripherals and interfaces, and enabling the processor to be put in standby mode.
