ATMEGA8A-PU

ATMEGA8 is a 28 pin AVR microcontroller. Although we have many similar microcontrollers, ATMEGA8 is popular because it is one of the cheapest microcontroller and provides many features in lesser pins. With program memory of 8Kbytes, ATMEGA8 application is very versatile. With various POWER SAVING modes it can work on MOBILE EMBEDDED SYSTEMS. With 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 ATMEGA8 popular.
