Summary 64-QFN, 8-bitMicrocontroller, High-performance, Low-power, Two 8-bit PWM Channels

Description as follow:

The ATMEGA644PA-AU 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-AU achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. By combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic chip, the ATMEGA644PA-AU is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications.
