The AT91FR40161 is a member of the Atmel AT91 16/32-bit Microcontroller family, which is based on the ARM7TDMI processor core. The processor has a high-performance 32-bit RISC architecture with a high-density 16-bit instruction set and very low power consumption. A large number of internally banked registers result in very fast exception handling, making the device ideal for real- ime control applications. The eight-level priority-vectored interrupt controller, together with the Peripheral Data Controller, significantly enhance real-time device performance.
