Overview
Block Diagram
2486ZS–AVR–02/11
The ATmega8 is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture.
By executing powerful instructions in a single clock cycle, the ATmega8 achieves throughputs
approaching 1 MIPS per MHz, allowing the system designer to optimize power consumption ver-
sus processing speed.
