Use Arduino as an ISP programmer to program non-Arduino AVR microcontrollers. When I type the program in Arduino IDE, I have to define the pin name as.

P in 28-pin narrow dual in-line package (-28N). It is commonly found on older boards. AVR is a family of developed since 1996 by, acquired by in 2016. These are single-chip microcontrollers.

AVR was one of the first microcontroller families to use on-chip for program storage, as opposed to,, or used by other microcontrollers at the time. AVR microcontrollers find many applications as. They are especially common in hobbyist and educational embedded applications, popularized by their inclusion in many of the line of development boards.

The original AVR MCU was developed at a local house in, called Nordic VLSI at the time, now, where Bogen and Wollan were working as students. [ ] It was known as a μRISC (Micro RISC) and was available as silicon IP/building block from Nordic VLSI. When the technology was sold to Atmel from Nordic, the internal architecture was further developed by Bogen and Wollan at Atmel Norway, a subsidiary of Atmel. The designers worked closely with compiler writers at to ensure that the AVR instruction set provided efficient of. Atmel says that the name AVR is not an acronym and does not stand for anything in particular.

The creators of the AVR give no definitive answer as to what the term 'AVR' stands for. However, it is commonly accepted that AVR stands for Alf and Vegard's RISC processor.

Note that the use of 'AVR' in this article generally refers to the 8-bit RISC line of Atmel AVR Microcontrollers. Among the first of the AVR line was the AT90S8515, which in a 40-pin DIP package has the same pinout as an microcontroller, including the external multiplexed address and data bus. The polarity of the RESET line was opposite (8051's having an active-high RESET, while the AVR has an active-low RESET), but other than that the pinout was identical. The AVR 8-bit microcontroller architecture was introduced in 1997. By 2003, Atmel had shipped 500 million AVR flash microcontrollers.

The platform, developed for simple electronics projects, was released in 2005 and featured ATmega8 AVR microcontrollers. Device overview [ ] The AVR is a machine, where program and data are stored in separate physical memory systems that appear in different address spaces, but having the ability to read data items from program memory using special instructions. Basic families [ ] AVRs are generally classified into following: • tinyAVR – the ATtiny series. Main article: In 2006, Atmel released microcontrollers based on the 32-bit architecture. This was a completely different architecture unrelated to the 8-bit AVR, intended to compete with the -based processors. It had a 32-bit data path, and instructions, along with other audio- and video-processing features.

The instruction set was similar to other RISC cores, but it was not compatible with the original AVR (nor any of the various ARM cores). Since then support for AVR32 has been dropped from Linux as of kernel 4.12; Atmel has switched mostly to M variants of the ARM architecture. Device architecture [ ],, and are all integrated onto a single chip, removing the need for external memory in most applications. Some devices have a parallel external bus option to allow adding additional data memory or memory-mapped devices. Almost all devices (except the smallest TinyAVR chips) have serial interfaces, which can be used to connect larger serial EEPROMs or flash chips. Program memory [ ] Program instructions are stored in. Although the are 8-bit, each instruction takes one or two 16-bit words.
