AVR Training

The AVR is a modified Harvard architecture 8-bit RISC single chip microcontroller which was developed by Atmel in 1996. The AVR was one of the first microcontroller families to use on-chip flash memory for program storage, as opposed to One-Time Programmable ROM, EPROM, or EEPROM used by other microcontrollers at the time.

“The AVR architecture was conceived by two students at the Norwegian Institute of Technology (NTH) Alf-Egil Bogen and Vegard Wollan“

Basic families

• tinyAVR — the ATtiny series
  • 0.5–8 kB program memory
  • 6–32-pin package
  • Limited peripheral set

• megaAVR — the ATmega series4–256 kB program memory
  • 28–100-pin package
  • Extended instruction set (Multiply instructions and instructions for handling larger program memories)
  • Extensive peripheral set

• XMEGA — the ATxmega series
  • 16–384 kB program memory
  • 44–64–100-pin package (A4, A3, A1)
  • Extended performance features, such as DMA, “Event System”, and cryptography support.
  • Extensive peripheral set with DACs
