ATmega64A
DATASHEET COMPLETE
Introduction
The Atmel® ATmega64A 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 ATmega64A achieves throughputs close to
1MIPS per MHz. This empowers system designer to optimize the device for
power consumption versus processing speed.
