"The AVRs are a family of RISC microcontrollers from Atmel (NASDAQ symbol: ATML).

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

The internal architecture was further developed by Alf and Vergard at Atmel Norway, a subsidiary of Atmel founded by the two architects.

The acronym AVR has been reported to stand for Advanced Virtual RISC, but it has also been rumoured to stand for the initials chip's designers: Alf and Vegard [RISC].

Note that the use of "AVR" in this article generally refers to the 8-bit RISC line of Atmel AVR Microcontrollers.

The AVR is a Harvard architecture machine with programs and data stored separately. Typical Harvard type machines store their programs in permanent or semi-permanent memory and data in volatile memory. Hence, they are ideal for embedded systems in the field, since the program memory is protected from voltage spikes and other harsh environmental factors that might corrupt the program.

Flash, EEPROM, and SRAM are all integrated onto a single chip, removing the need for external memory (though still available on some devices).

Three Basic Families

AVRs are generally classified into three broad groups:

TinyAVRs 1-8kB program memory 8-20 pin package Limited peripheral set

MegaAVRs 4-256kB program memory 28-100 pin package Extended instruction set (Multiply instructions and instructions for handling larger program memories) Extensive peripheral set

Application specific AVRs megaAVRs with special features not found on the other members of the AVR family, such as LCD controller, USB controller, advanced PWM etc."
