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.
The AVR architecture was conceived by two students at the Norwegian Institute of Technology (NTH), [1] Alf-Egil Bogen [2] and Vegard Wollan. [3] 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. [3]
MicroPython is a software implementation of a programming language largely compatible with Python 3, written in C, that is optimized to run on a microcontroller. [2] [3] MicroPython consists of a Python compiler to bytecode and a runtime interpreter of that bytecode.

[5] C Programming for Microcontrollers, a book for learning to program AVRs using C, was written for the Butterfly as development platform. [6] [7] The Butterfly Logger is an open source data logger based on the AVR Butterfly. [8] The Butteruino project is a set of libraries to integrate the AVR Butterfly with the Arduino development ...
The Atmel 8-bit AVR RISC-based microcontroller combines 32 KB ISP flash memory with read-while-write capabilities, 1 KB EEPROM, 2 KB SRAM, 23 general-purpose I/O lines, 32 general-purpose working registers, 3 flexible timer/counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented 2-wire serial ...
They also sell the Zigbit module that comes with FCC certifications. Atmel also makes remote control RF products using the license-free ISM band (industrial scientific medical) frequencies (5.8 GHz, 2.4 GHz, 868 to 928 MHz, 433 MHz, and 315 MHz). [33] The wireless segment also provides RFID chips for tracking, access and identification. Finally ...
Examples include the PIC by Microchip Technology, Inc. and the AVR by Atmel Corp (now part of Microchip Technology). Even in these cases, it is common to employ special instructions in order to access program memory as though it were data for read-only tables, or for reprogramming; those processors are modified Harvard architecture processors.
