Atmega128a - Low-power Cmos 8-bit Microcontroller At 2.7-5.5v | 133 Powerful Instructions, 16mhz Operation, Advanced Risc Architecture, Extensive On-chip Debug Support, 128kb Flash Memory, Capacitive Touch Support

The ATMEGA128A is a low-power CMOS 8-bit microcontroller based on the AVRAR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATMEGA128A achieves through puts close to 1MIPS per MHz. This empowers system designer to optimize the device for power consumption versus processing speed.
