Atmega8 also known as ATMEL ATMEGA8L 8PU is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture. By executing powerful instructions in a single clock cycle.

ATmega8 / Atmel Atmega8 Microcontroller achieves throughputs approaching 1 MIPS per MHz, allowing the system designer to optimize power consumption versus processing speed.

ATMega8 AVR Microcontroller is a 28 pin AVR microcontroller. Although we have many similar microcontrollers. ATmega8 AVR Microcontroller is popular because it is one of the cheapest microcontroller and provides many features in lesser pins.

With program memory of 8Kbytes, ATMega8L AVR Microcontroller application is very versatile. Various POWER SAVING modes it can work on MOBILE EMBEDDED SYSTEMS. its compact size it can be put in many small boards. With Watchdog timer to reset under error it can be used on systems with minimal human interference.

These features added together in one controller make the ATMega8L AVR Microcontroller popular. ATMEL ATMEGA8L 8PU has 23 programmable input/output (I/O) pins which can be used for interfacing with external world.

It is possible to configure them as input or output by setting a particular register value through programming.

Atmel Atmega8 AVR Microcontroller core combines a rich instruction set with 32 general purpose working registers.

All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one single instruction executed in one clock cycle.
