ATMEGA64A-AU

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P18P19-P20
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.
