8-bit AVR Microcontroller ATmega128A
DATASHEET COMPLETE Introduction
В® The Atmel ATmega128A is a low-power CMOS 8-bit microcontroller based
В®
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. Features High-performance, Low-power Atmel AVR 8-bit Microcontroller
