Introduction
The Atmel® ATmega128A is a low-power CMOS 8-bit microcontroller based on the AVR® enhanced RISC architecture. By executing powerful instructions in a single clock cycle,
the ATmega128A achieves throughputs close to 1MIPS per MHz.
This empowers system designer to optimize the device for power consumption versus processing speed.
