Atmel ATmega128-16AU AVR Microcontroller, 64 QFP, 16 MHz

The ATmega128 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 ATmega128 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. The ATmega128-16AU is the Pb-free version of the ATmega128-16AI. It is functionally identical.
