![]() With various POWER SAVING modes, it can work on MOBILE EMBEDDED SYSTEMS. With program memory of 8Kbytes, ATMEGA8 application is very versatile. Although we have many similar microcontrollers, ATMEGA8 is popular because it is one of the cheapest microcontroller and provides many features in lesser pins. Note: Complete technical information can be found in the ATMEGA8 Microcontroller Datasheet linked at the bottom of this page.ĪTMEGA8 is a 28 pin AVR microcontroller. 55☌ to +125☌(+125 being absolute maximum, -55 being absolute minimum) Programmable Watchdog Timer with Separate On-chip Oscillator Master/Slave SPI Serial Interface(16,17,18,19 PINS) +4.5 V TO +5.5 V (ATmega8) (+5.5V being absolute maximum) SDA (Two-wire Serial Bus Data Input/Output Line) This is the clock shared between this controller and other system for accurate data transfer. When controller acts as slave, the data is sent to master by this controller through this pin. OC2 (Timer/Counter2 Output Compare Match Output) When controller acts as slave, the data is received by this pin. OC1B (Timer/Counter1 Output Compare Match B Output) This pin is low when controller acts as slave. OC1A (Timer/Counter1 Output Compare Match A Output) XTAL1 (Chip Clock Oscillator pin 1 or External clock input) ![]() ![]() If the RSTDISBL Fuse is programmed, PC6 can be used as an I/O pin.
