ATMEGA 1280V8 AU – 8-Bit-ATMega AVR® Mikrocontroller, 128 kB, 8 MHz, TQFP-100

The ATmega640/1280/1281/2560/2561 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing pow erful instructions in a single clock cycle, the ATmega640/1280/1281/2560/2561 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 regis- ters. 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 wh ile achieving throughputs up to ten times faster than conventional CISC microcontrollers.
