ATMEGA644PA-AUR Product Details
ATMEGA644PA-AUR Description
The Atmel ATMEGA644PA-AUR 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 ATMEGA644PA-AUR achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
