ATmega8(L)
Overview
The AtmelAVR 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 1MIPS per MHz, allowing the system designer to optimize power con-
sumption versus processing speed.
