arduino atmega2560 datasheet pdf - The ATmega2560 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture.
By executing powerful instructions in a single clock cycle, theATmega2560 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
The Atmel AVR core combines a rich instruction set with 32 general purpose working registers.
All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle.
The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.
The Idle mode stops the CPU whileallowing the SRAM, Timer/Counters, SPI port, and interrupt system to continue functioning.
The Power-down mode saves the register contents but freezes the Oscillator, disabling all other chip functions until the next interruptor Hardware Reset.
In Power-save mode, the asynchronous timer continues to run, allowing the user to maintain atimer base while the rest of the device is sleeping.
The ADC Noise Reduction mode stops the CPU and all I/O mod-ules except Asynchronous Timer and ADC, to minimize switching noise during ADC conversions.
In Standby mode, the Crystal/Resonator Oscillator is running while the rest of the device is sleeping. This allows very faststart-up combined with low power consumption. In Extended Standby mode, both the main Oscillator and the Asynchronous Timer continue to run.
The ATmega2560 AVR is supported with a full suite of program and system development tools including: C compilers, macro assemblers, program debugger/simulators, in-circuit emulators, and evaluation kits.
