The Atmel AVR instruction set is the machine language for the Atmel AVR, 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.
Atmel Mega88V with 8 KB Flash memory Variant ATmega168 with 16 KB Flash memory. The ATmega88 is an electronic integrated circuit microcontroller produced by the Atmel corporation. It has the basic Atmel AVR instruction set. One of the packaging configurations is the dual in-line package . It has 23 I/O pins and operates at up to 20 MHz for ...
The AVR Dragon provides in-system serial programming, high-voltage serial programming and parallel programming, as well as JTAG or debugWIRE emulation for parts with 32 KB of program memory or less. ATMEL changed the debugging feature of AVR Dragon with the latest firmware of AVR Studio 4 - AVR Studio 5 and now it supports devices over 32 KB of ...
For example, LPM (Load Program Memory) and SPM (Store Program Memory) instructions in the Atmel AVR implement such a modification. Similar solutions are found in other microcontrollers such as the PIC and Z8Encore!, many families of digital signal processors such as the TI C55x cores, and more. Because instruction execution is still restricted ...
ATmega328 is commonly used in many projects and autonomous systems where a simple, low-powered, low-cost micro-controller is needed. Perhaps the most common implementation of this chip is on the popular Arduino development platform, namely the Arduino Uno, Arduino Pro Mini [4] and Arduino Nano models.

In 2007, Atmel launched the second AVR32: The AVR32 UC3 core. This is designed for microcontrollers, using on-chip flash memory for program storage and running without an MMU (memory management unit). The AVR32 UC3 core uses a three-stage pipelined Harvard architecture specially designed to optimize instruction fetches from on-chip flash memory ...
Atmel AVR, used in a variety of products ranging from Xbox handheld controllers and the Arduino open-source microcontroller platform to BMW cars. RISC-V , the current iteration of Berkeley's open standard RISC ISA, with 32- or 64-bit address spaces , a small core integer instruction set, and an experimental "Compressed" ISA for code density and ...
