ATMEL 8-Bit AVR Microcontroller, 32KB Flash, 32-TQFP

The ATMEL 8-Bit AVR Microcontroller is a high-performance, low-power CMOS microcontroller unit based on the advanced AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, this microcontroller achieves throughputs approaching 1MIPS per MHz, enabling system designers to effectively optimise power consumption versus processing speed.

The AVR core combines a rich instruction set with 32 general purpose working registers. All 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in a single clock cycle. The resulting architecture is significantly more code efficient whilst achieving throughputs up to ten times faster than conventional CISC microcontrollers.
