Product Summary

The ATMEGA8A-AU is a low power CMOS 8 bit microcontroller based on the AVR RISC architecture. By executing powerful instructions in a single clock cycle, the ATMEGA8A-AU achieves throughputs approaching 1 MIPS per MHz, allowing the system designer to optimize power consumption versus processing speed.
