When the technology was sold to Atmel from Nordic VLSI, the internal architecture was further developed by Bogen and Wollan at Atmel Norway, a subsidiary of Atmel. It was known as a μRISC (Micro RISC) and was available as silicon IP/building block from Nordic VLSI. The original AVR MCU was developed at a local ASIC house in Trondheim, Norway, called Nordic VLSI at the time, now Nordic Semiconductor, where Bogen and Wollan were working as students. Note that the use of "AVR" in this article generally refers to the 8-bit RISC line of Atmel AVR microcontrollers. However, it is commonly accepted that AVR stands for Alf and Vegard's RISC processor. The creators of the AVR give no definitive answer as to what the term "AVR" stands for. Ītmel says that the name AVR is not an acronym and does not stand for anything in particular. The AVR architecture was conceived by two students at the Norwegian Institute of Technology (NTH), Alf-Egil Bogen and Vegard Wollan. They are especially common in hobbyist and educational embedded applications, popularized by their inclusion in many of the Arduino line of open hardware development boards. 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.ĪVR microcontrollers find many applications as embedded systems. These are modified Harvard architecture 8-bit RISC single-chip microcontrollers. It is commonly found on Arduino boards.ĪVR is a family of microcontrollers developed since 1996 by Atmel, acquired by Microchip Technology in 2016. ATmega328P in 28-pin narrow dual in-line package ( DIP-28N). AVR logo Various older AVR microcontrollers: ATmega8 in 28-pin narrow dual in-line package ( DIP-28N), ATxmega128A1 in 100-pin thin quad flat pack ( TQFP-100) package, ATtiny45 in 8-pin small outline ( SO-8) package. For the AVR instruction set, see Atmel AVR instruction set. This article is about the series of AVR microcontrollers.
