ATmega128A
DATASHEET SUMMARY
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.
