8Kbytes of In-System Self-Programmable Flash program memory.High Endurance Non-volatile Memory segments:.32 × 8 General Purpose Working Registers.130 Powerful Instructions – Most Single-clock Cycle Execution.By executing powerful instructions in a single clock cycle, the ATmega8 achieves throughputs approaching 1 MIPS per MHz, allowing the system designer to optimize power consumption versus processing speed. The ATmega8 is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture.
#Atmega8 pin diagram driver
because it is a very good standard microcontroller for you if you want to learn the microcontroller driver programming. There are so many controllers variants available, but I am considering ATMEGA-8 microcontroller. Here I am going to discuss the AVR microcontroller. There is so much Processor design architecture, and I think most of the important architectures you can get here in my processor page. It consumes very little power and can have different modes to control the power consumption for devices. The AVR microcontrollers are 4 times faster than PIC microcontrollers. The AVR microcontroller is very fast than others which can able to execute most of the instructions in one execution cycle.
Mostly it is used for commercial purposes. X-Mega AVR: This is the most high-end controller used for complex microcontrollers that need more FLASH & RAM memory with high-speed operation.Mega AVR: This is the most popular used microcontroller in the market which is having flash memory up to 256kb, number of peripherals, and it is suitable for moderate to complex applications.Tiny AVR: Small in size and very less memory used for small applications.The first AVR microcontroller was AT90S8515 but it was not able to interrupt the commercial market with the competitor where after the AT90S1200 was started his business in the commercial market in the year 1997.īasically, the AVR architecture is available in 3 categories in the market for their different features as: This architecture was designed by Alf-Egil Bogen and Vegard Wollan and the naming convention was derived from both the developers and it stands for Alf-Egil Bogen Vegard Wollan RISC microcontroller and mostly we called it as Advanced Virtual RISC machine. It was developed in the year 1996 by ATMEL Corporation. The AVR is one of the most powerful architecture in processor design.
