The ATMEGA16A is a low-power CMOS 8-bit microcontroller based on the Atmel AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATMEGA16A achieves through puts approaching 1MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.
