AVR Microcontroller

AVR was developed by Bogen and Wollan at Atmel Norway in the year 1996 with on-chip flash memory. The AVR (also known as Advanced Virtual RISC) is a modified Harvard architecture machine where program and data are stored in separate physical memory systems. AVR microcontrollers deliver a unique combination of performance, power efficiency, and design flexibility, they are based on the industry’s most code-efficient architecture for C and assembly programming.
