The AVR Microcontroller The AVR enhanced RISC microcontrollers [1] are based on a new RISC architecture that has been developed to take advantage of semiconductor integration and software capabilities of the 1990's. A block diagram of the AVR architecture is given in figure 1. The memory sizes and peripherals indicated in the figure are for the AT90S8414 microcontroller.Central in the AVR architecture...
