When and How Will the World End AVR Microchip PIC Microcontroller
Programming and Customizing the AVR MicrocontrollerAVR microcontrollers, the 8-bit RISC line of Atmel, were founded by two college students, Alf-Egil Bogan and Vegard Wollan from the Norwegian Institute of Technology. AVR's come from the family of RISC microcontrollers from Atmel. It is thought that AVR stands for Advanced Virtual RISC but it could stand for the students who designed them. Alf and Vegard and the R for RISC. It would seem that the better idea would be that it stood for the inventors. They haven't given an answer for what AVR stands for but The inventors deserve credit for their good work. Why should anyone complain?
The AVR microcontrollers are a Harvard machine where the programs and data are stored separately unlike the typical Harvard types, which store their material in a permanent or semi permanent memory. The need for external memory is unnecessary because Flash, EEPROM, and SRAM are all on the same chip.
The AVR microcontroller comes in three basic families. TinyAVR's, megaAVR's and Application specific AVR's. One of the first AVR microcontrollers was the AT90S8515. This AVR has a 40-pin DIP package, which was the same as the 8051 microcontroller except that the 8051 have an active-high RESET and the AT90S8515 has an active-low RESET.

Dear AVR Microcontroller Enthusiasts,I am writing to you in behalf of your Heavenly Father. He is seeking you like a lost sheep. You remember the Bible story? It is about a shepherd who has 100 sheep. But when he brings the sheep home one night, one is missing. He then leaves the 99 sheep and goes out into the wilderness until he finds that lost sheep.
In this parable the shepherd goes out to search for the one lost sheep-the very least that can be numbered. So if there had been but one lost soul, Christ would have died for that one. To read more click Lost Sheep
