Datasheet Atmel ATmega644PV-10MUR — Ficha de datos

8-bit AVR Microcontrollers ATmega644P/V
DATASHEET COMPLETE Introduction
® ® The Atmel picoPower ATmega644P 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 ATmega644P
achieves throughputs close to 1MIPS per MHz. This empowers system
designer to optimize the device for power consumption versus processing
speed. Feature
