8-bit AVR Micrcontroller ATmega64A DATASHEET SUMMARY 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.
