The Microchip AVR® ATmega8A 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 achieves throughputs approaching 1 MIPS per MHz, allowing the system designer to optimize power consumption versus processing speed.
Features of Atmega8A Microcontroller:-
- Operating Voltage: 4.5V to 5V.
- Advanced RISC Architecture.
- 32 x 8 General Purpose Working Registers.
