Black Atmega128a Low-power Cmos 8-bit Microcontroller Based On The Avrar Enhanced Risc Architecture

The ATMEGA128A is a low-power CMOS 8-bit microcontroller based on the AVRAR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATMEGA128A achieves through puts close to 1MIPS per MHz. This empowers system designer to optimize the device for power consumption versus processing speed.
